Trump Tariffs Are Essential to American Domestic and Foreign Policy

Tariffs are taxes on goods that come into our country from other countries. When we charge a tariff, it means foreign companies have to pay to sell their products here. That money goes to the United States, not to the other countries.

They’re essential because they protect American workers and factories. For years, other nations — especially China — have been taking advantage of the U.S. by selling cheap goods, stealing our technology, and hurting our industries. Tariffs level the playing field. They make it fair again.

Domestically, tariffs bring back jobs and manufacturing. They encourage companies to build and produce here in America instead of overseas. In foreign policy, tariffs give us leverage. When countries know we’re willing to use tariffs, they respect us more and negotiate better trade deals.

In short: tariffs protect American jobs, strengthen our economy, and make other countries treat us fairly. That’s putting America First.

Historical Background and Foundational Principles

Tariffs have been interwoven with American policy since the nation’s founding. In fact, the very first Congress passed the Tariff Act of 1789, recognizing import duties as a crucial revenue source for the new federal government. Throughout the Republic’s early decades, tariffs provided the lion’s share of national income — roughly 90% of federal revenues from 1790 to 1860 — in an era when no federal income tax existed. Beyond raising funds, these early tariffs reflected Alexander Hamilton’s vision that protective duties could nurture “infant industries” until they matured to compete internationally. For example, Treasury Secretary Hamilton argued young American manufacturers needed temporary shelter from British imports, lest nascent industries wither under foreign competition. This protectionist logic took root in the North’s manufacturing centers and became a bedrock of early U.S. economic strategy. Meanwhile, agricultural exporters, especially in the South, bristled at high import taxes that raised prices on consumer goods and invited foreign retaliation against American cotton and tobacco. Tariff policy thus quickly became a flashpoint of sectional and political conflict in the 19th century, from the “Tariff of Abominations” (1828) controversy to the Nullification Crisis a few years later. These clashes underscored that tariffs were not just technical economic measures but core issues of political economy, pitting free trade ideals against protectionist interests — a tension that would ebb and flow through U.S. history.

By the Civil War and Gilded Age, protectionism largely carried the day. The Republican Party, spearheading industrial growth, championed stiff tariffs to guard burgeoning steel mills, textile factories, and other manufacturers from European competition. Once the Union imposed the Morrill Tariff of 1861 to help finance the war (and encourage domestic industry), high tariffs remained a staple policy for decades. Average import duties often exceeded 30–40% in the late 19th century, and the U.S. experienced rapid industrialization under this protective umbrella. However, these steep tariffs came at a cost: U.S. farmers and consumers paid higher prices, and foreign nations struck back with barriers against American goods. The Smoot-Hawley Tariff Act of 1930, an infamous culmination of protectionist fervor, hiked duties on over 20,000 products in the midst of the Great Depression. The result was a global trade war: other countries retaliated in kind, world trade plummeted, and the economic crisis deepened. Smoot-Hawley’s fallout cemented a lesson for U.S. policymakers about the perils of beggar-thy-neighbor tariff spirals. In response, a seismic shift in trade strategy occurred under Franklin D. Roosevelt. Congress passed the Reciprocal Trade Agreements Act of 1934, delegating new authority to the President to negotiate tariff reductions bilaterally. The aim was reciprocal market opening — exchanging lower U.S. tariffs for foreign tariff cuts — to revive global commerce. This marked the birth of a new era: for roughly the next 80 years (1934–2016), the overriding objective of U.S. trade policy was to reduce barriers and promote freer trade, not erect new tariffs. Through the General Agreement on Tariffs and Trade (GATT) after World War II, and eventually the World Trade Organization (WTO) system, the United States led a long wave of tariff liberalization. Average U.S. tariff rates steadily fell to historic lows (around 2–3% on imports in recent decades) as numerous trade agreements slashed duties on thousands of goods. By the turn of the 21st century, tariffs had largely faded into the background of policy tools — still collected, but no longer central to economic strategy — while free trade orthodoxy reigned in Washington.

That orthodoxy, however, did not go unchallenged. Beneath the surface, domestic discontent simmered over factory job losses attributed to imports and trade deficits with nations like China. Politicians in both parties began questioning the free trade consensus, especially after China’s 2001 WTO entry and the ensuing “China shock” to U.S. manufacturing. The stage was set for a dramatic policy reversal. In 2018, President Donald Trump emphatically broke with decades of precedent by wielding tariffs as a blunt instrument of economic statecraft. Citing “decades of imbalances” and “unfair trade” harming U.S. industries, the Trump administration imposed sweeping new tariffs on steel and aluminum imports worldwide, as well as on $360 billion worth of Chinese goods ranging from machinery to electronics. These actions — justified by invoking national security (for metals) and retaliation for intellectual property theft (for China) — jolted the global trading system and ignited the first major trade war of the post-Cold War era. Not since the 1930s had the United States so aggressively raised barriers against its trading partners. Import taxes, long a secondary tool, suddenly were front-page policy once more. Notably, this resurgence of tariffs did not end when Trump left office. President Joe Biden, taking office in 2021, largely left Trump’s tariffs intact — and even added his own targeted tariffs in sectors like technology and renewable energy. In doing so, Biden helped solidify what observers call a new bipartisan consensus that tariffs and protectionist measures are sometimes essential tools to bolster domestic industry and pursue strategic aims. This sharp turn, especially after 2016, signifies a full circle in U.S. trade history: from revenue generation, to protectionism, to multilateral free trade — and now back toward selective protection — all reflecting changing assessments of how tariffs serve American domestic and foreign policy goals.

Underlying Assumptions and Inconsistencies

The recent revival of U.S. tariffs rests on several core assumptions — some explicit, others implicit — about economics and national interest. Examining these underlying beliefs reveals both the rationale for tariff use and the inconsistencies or biases that accompany it. One fundamental assumption is that tariffs protect American jobs and industries. Protectionists presume that raising the cost of imports will divert demand toward domestic products, thereby boosting U.S. factories and workers. This assumption has deep roots: Hamilton’s “infant industry” theory held that temporary tariffs could foster nascent sectors until they achieve economies of scale. Even today, officials justify tariffs by pointing to shuttered steel mills or textile plants that might restart if overseas competitors face a price handicap in the U.S. market. Closely related is the belief that tariffs enhance national security by reducing dependence on foreign supplies of critical goods. This was invoked in 2018 when the administration argued that steel imports threatened America’s industrial base, and again in 2023–24 when new tariffs targeted Chinese solar panels, batteries, and semiconductors deemed vital for economic security. The assumption is that a nation reliant on strategic adversaries for key materials or technologies could find itself vulnerable; tariffs are seen as a way to nurture domestic capacity in defense-related or “future frontier” industries (like clean energy and microchips). A further premise driving tariff policy is the notion that trade deficits are inherently harmful — a sign of lost jobs and unfair practices — and that tariffs can help close the gap. Both the Trump and Biden administrations asserted that decades of large U.S. trade deficits (especially with China) reflect imbalance and foreign manipulation. Implicitly, tariffs are viewed as a tool to rectify these imbalances by curbing imports and thus shrinking the deficit. Finally, there is a tactical assumption: that the threat or imposition of tariffs gives the U.S. leverage to extract concessions from other countries. In this view, tariffs are a bargaining chip — painful enough to force negotiating partners to address U.S. grievances (be it better market access, stricter intellectual property protections, or non-trade issues like immigration control). This was clearly at play in 2019 when President Trump threatened sweeping tariffs on all Mexican goods to compel Mexico’s cooperation on stemming northward migration. The underlying faith is that trading partners, fearing loss of the lucrative American market, will eventually yield under tariff pressure.

Each of these assumptions, however, is contested by economists and has inherent inconsistencies. Take the jobs and industry protection claim: while tariffs do shield specific factories by making foreign rivals more expensive, they also raise costs for downstream industries and consumers. This can lose jobs in sectors that rely on imported inputs or face retaliatory export barriers. For example, tariffs on imported steel benefit steel mills but hurt U.S. automakers and construction firms with higher steel costs; some estimates found that in 2018, U.S. steel-using industries shed more jobs than were saved in steel production, due to higher input prices. Likewise, protecting one sector often simply shifts resources within the economy rather than creating net new growth. A bias known as the “seen vs. unseen” effect often operates: policymakers see the factory re-opening attributed to tariffs (the visible benefit), but the diffuse harm — higher prices for millions of consumers, or the business expansions that never happen due to costlier inputs — remains largely unseen. National security arguments for tariffs also reveal inconsistencies. Critics note that in 2018 the U.S. invoked “national security” to tariff steel from close allies like Canada, Germany, and Japan — a move many viewed as a pretext for protectionism rather than a genuine security threat. The broad definition of security risked undermining U.S. credibility, as even Pentagon officials stated allied imports weren’t jeopardizing defense needs. The assumption that more self-sufficiency equals more security can be taken to extremes: autarky (complete economic self-reliance) might maximize supply security but would impoverish the nation. Thus, a balance must be struck, and tariffs are a blunt tool that can backfire if partners retaliate or if domestic producers grow complacent behind protection. The trade deficit assumption contains a well-known macroeconomic inconsistency: a nation’s trade balance is largely determined by its savings and investment gap, not by tariff levels alone. In other words, the U.S. runs trade deficits because it consumes and invests more than it saves, financing the difference by importing capital. Slapping tariffs on imports may curb some imports but often leads to countermeasures that reduce exports, leaving the overall trade balance little changed. Indeed, in the 2018–2019 tariff war, the U.S. trade deficit with China initially shrank, but deficits with other countries grew as imports were diverted rather than eliminated. Total U.S. imports and the overall trade deficit actually hit record highs during the tariff era, undercutting the notion that tariffs automatically “fix” deficits. There is a bias, some argue, in viewing trade as zero-sum — assuming any deficit is a loss. This mercantilist mindset equates exports with winning and imports with losing, whereas classical economics holds that all trade (even imports) can benefit consumers and firms via lower prices and greater variety. Tariffs based on a zero-sum bias risk sacrificing those broad consumer benefits for narrow producer gains.

As for using tariffs as leverage, history shows mixed results. While tariff threats sometimes extract short-term concessions (Mexico’s quick deployment of its National Guard to avoid Trump’s 2019 tariffs is one example), they also breed resentment and tit-for-tat retaliation. Other countries can be unwilling to negotiate “with a gun to their head,” instead digging in or retaliating to save face. China’s response to U.S. tariffs was not capitulation on all fronts; rather, Beijing countered with its own tariffs on American goods (hitting U.S. farmers particularly hard) and doubled down on industrial subsidies to weather the storm. The 2020 “Phase One” trade deal that the U.S. pressured China into signing achieved some increased purchases of U.S. goods, but it didn’t fundamentally change China’s core trade practices like subsidization or tech transfer rules. This highlights an inconsistency in the coercive tariff strategy: tariffs can impose costs, but they are a blunt instrument ill-suited to resolving complex structural disputes. In some cases, they can even be counterproductive — for instance, tariffs on allies in hopes of gaining geopolitical cooperation (as with the Mexican immigration issue or Trump’s flirtation with taxing European autos) risk undermining the very alliances and goodwill needed for broader foreign-policy objectives. Lastly, a notable bias in tariff debates is the distributional blind spot: proponents focus on benefits to industries and workers in import-competing sectors, whereas opponents emphasize costs to consumers (especially low-income households, who spend a larger share of income on tradable goods). Tariffs function as a regressive tax; whether or not foreign producers nominally “pay” at the border, much of the expense passes through to domestic prices. Studies during the recent trade war found that American consumers and importing firms absorbed the vast majority of tariff costs in higher prices, not foreign exporters. This runs contrary to some political rhetoric that “foreign countries are paying the tariffs.” The inconsistency between that claim and real price data underscores how economic reality can diverge from the simplistic assumptions sometimes used to sell tariff policy. In sum, the revival of tariffs in U.S. policy carries a tangle of motivations — some pragmatic, some political — each accompanied by caveats. The challenge for policymakers is untangling where tariffs truly serve the national interest (e.g., remedying a specific market distortion) versus where they satisfy a political instinct but introduce inefficiencies or unintended harms.

Competing Perspectives and Counterarguments

Debates over tariff policy feature a spectrum of perspectives, from ardent protectionists to staunch free traders, with nuanced positions in between. Understanding these competing viewpoints is essential for a rounded analysis of tariffs’ role.

Protectionist & Strategic Advocates: On one side are those who argue tariffs are not only justified but necessary for America’s economic health and sovereignty. This view, often associated with economic nationalists, organized labor, and some industrial policymakers, sees tariffs as a tool to level the playing field. Advocates point out that many foreign governments actively support their industries — through subsidies, currency manipulation, lax labor and environmental rules, or even overt mercantilism — which can flood the U.S. market with underpriced goods. In their eyes, free trade under such conditions is an illusion: American firms and workers face “unfair” competition. Tariffs, then, serve as a counterweight to these distortions. For example, China’s government has long subsidized steel production, leading to a global glut of cheap steel that undercuts U.S. mills. By imposing tariffs on steel imports, the U.S. can counteract the price advantage conferred by those subsidies and save a strategically important industry. Pro-tariff thinkers often invoke the success of past U.S. industrialization under high tariffs (19th-century America, as well as post-war Japan or South Korea, are cited as cases where temporary protection led to booming industries). They also align with the Hamiltonian “infant industry” argument: emerging sectors like clean energy technology or advanced batteries may need tariff protection against dominant foreign producers (often backed by state capital) to grow domestically.

National security hawks in this camp underscore that certain supply chains — semiconductors, medical supplies, rare earth minerals — are too critical to be left to offshore producers, especially producers in rival nations. Tariffs can incentivize onshoring or “friend-shoring” (shifting supply to allied countries) by penalizing imports from adversaries. This perspective gained traction during the COVID-19 pandemic, when the U.S. found itself scrambling for foreign-made personal protective equipment and pharmaceuticals. It became painfully clear that unfettered free trade had left some vulnerabilities. Likewise, the clean energy transition has strategic dimensions: tariffs on Chinese solar panels or electric vehicles are seen as a way to prevent Beijing from monopolizing those future industries and to support American manufacturing of green tech. Strategic advocates concede tariffs are not a cure-all, but argue they are a vital component of a broader industrial policy toolkit — alongside domestic investments, innovation subsidies, and skills training — to rebuild the U.S. productive base. They also propose creative uses of tariffs to advance non-economic goals: for instance, a system of “social tariffs” that are higher on imports from countries with poor labor standards or high carbon emissions, thereby pressuring improvements in those countries (and preventing a race to the bottom). In summary, the pro-tariff stance holds that judicious use of import taxes can correct market failures (like foreign dumping or subsidy-driven oversupply), protect good-paying jobs, enhance resilience in crucial sectors, and even uphold ethical standards in global commerce. Far from a bygone relic, tariffs for these advocates are essential instruments of statecraft — akin to sanctions or export controls — warranted by the extraordinary economic challenges of the 21st century (from Chinese state capitalism to climate change). Notably, this view has gained adherents on both the right and left of the U.S. political spectrum in recent years, forging an unusual coalition that insists the costs of certain tariffs are worth the benefits of economic security and national renewal.

Free Trade & Economic Liberal Critics: In stark contrast, classical economists, many business groups, and free-trade proponents see tariffs as largely counterproductive — “medicine” that often worsens the disease it aims to cure. The anti-tariff perspective begins with the principle of comparative advantage: each nation benefits by specializing in producing what it’s relatively efficient at and trading for the rest. Tariffs, in this view, are self-imposed wounds that distort this efficient allocation, raise costs, and invite retaliation. Critics argue that while tariffs may protect specific industries, they do so at a net cost to the economy — a cost borne by consumers and unprotected sectors. Decades of empirical studies show consumers typically pay higher prices when tariffs are enacted. For instance, when washing machines from abroad were hit with tariffs in 2018, the price of laundry equipment in the U.S. jumped roughly 12%, far above the tariff rate, because domestic producers seized the opportunity to raise their prices as well. In aggregate, tariffs act as a tax, and a regressive one at that. The Tax Foundation and others estimated that the post-2018 tariff suite amounted to an annual tax increase of around $1,300 per U.S. household, making it among the largest tax hikes in recent times (without the normal legislative process or offsets). Free trade advocates emphasize that these costs disproportionately impact lower-income Americans, who spend a higher fraction of earnings on imported necessities (apparel, electronics, etc.), essentially penalizing the poorest for the sake of aiding a relatively narrow set of producers. Moreover, tariff opponents underscore the danger of retaliation: when the U.S. taxes imports, other countries nearly always counter with tariffs on U.S. exports, as both historical and recent episodes confirm. American farmers learned this painfully in 2018–2019 when China, Canada, and the European Union slapped tariffs on U.S. soybeans, pork, dairy, and bourbon in response to U.S. measures. Exports of U.S. soy to China plummeted, and the federal government had to spend billions on farm bailouts to make up for lost markets. In effect, tariffs triggered a chain reaction requiring taxpayer-funded remedies — an outcome free traders decry as senseless self-harm.

Economists also challenge the strategic rationale for tariffs. They argue that if certain inputs or products are critical (steel for defense, for example), the government can more efficiently ensure supply through direct subsidies or stockpiling, rather than distorting the entire market with broad tariffs. A Hoover Institution analysis in 2020 noted that the U.S. Navy and defense contractors use a small fraction of domestic steel output; a targeted subsidy for maintaining extra capacity would be far cheaper than a 25% tariff on all steel, which hit thousands of downstream manufacturers. Additionally, free trade proponents point to the success of the post-WWII liberal trading order in fostering global prosperity and U.S. leadership. They warn that America’s turn toward tariffs undermines the very system it built, encouraging other nations to follow suit and potentially leading to a more fragmented, hostile trade environment. From this perspective, today’s calls for protectionism repeat mistakes of the past — recalling how tariffs worsened the Depression — and ignore how engagement and competition have historically strengthened the U.S. economy. For instance, industries exposed to competition (like autos in the 1980s) often innovated and became more efficient, whereas those long coddled by protection (like U.S. shipbuilding or the 1980s-era protected semiconductor industry) sometimes stagnated or fell behind. Critics contend that tariffs rarely achieve their stated goals: they do not decisively revive manufacturing (automation and technology play bigger roles in job losses), they do not reliably improve trade balances (currency and macro factors offset them), and they can strain diplomatic relations, thereby weakening national security in a broader sense. The Cato Institute encapsulated this view, calling tariffs “costly taxes” and “poor tools” for achieving strategic objectives or economic growth. In short, the anti-tariff camp considers open markets, albeit with fair rules, as the surest path to innovation, consumer welfare, and international cooperation — and sees the recent tariff revival as a dangerous regression.

Mixed or Conditional Perspectives: Between these poles, a significant middle ground of experts and policymakers takes a conditional stance: tariffs can be useful in moderation and for specific purposes, but they are not a panacea and must be carefully calibrated. This pragmatic view might agree with protectionists that certain targeted tariffs are warranted — for instance, anti-dumping duties and countervailing duties to combat demonstrable unfair trade practices by foreign companies or governments. Indeed, these narrowly focused tariffs have long been part of the trade remedy laws and are even allowed under WTO rules (when evidence of dumping or illegal subsidies is found). Imposing, say, a tariff on imported steel that’s subsidized by its home government can be seen as leveling the field rather than protectionism per se. Similarly, this middle view acknowledges that tariffs tied to clearly defined strategic goals — such as penalizing goods made with slave or child labor, or a prospective carbon border tariff to account for pollution — could correct market failures and uphold important values. However, proponents of a limited-use approach stress that tariffs work best as part of a larger strategy, not as a stand-alone policy. For example, a tariff to support the solar panel industry should be paired with domestic investment in R&D and scaling production, plus diplomatic efforts to address the root causes of China’s solar dominance (like subsidy disciplines). Without these flanking measures, a tariff alone might just raise U.S. prices without ensuring long-term competitiveness. The conditional camp is also very wary of overreach. They argue that broad-based tariff hikes across all sectors — such as across-the-board import taxes — are misguided, as these tend to inflict maximum consumer pain for minimal strategic gain. The Economic Policy Institute, a think tank that often supports labor-friendly policies, articulated this balance: tariffs are “absolutely a key tool of smart industrial and trade policy” when finely targeted, but “cannot and should not be the centerpiece” of national economic strategy in general. Over-reliance on tariffs, they caution, would be like using a hammer for every job — effective for some nails, but clumsy and damaging if applied indiscriminately.

This nuanced perspective also values the multilateral system: it suggests working through alliances and agreements where possible, even as the U.S. addresses problematic trade behavior. For instance, rather than unilateral U.S. tariffs on China alone, a coordinated response with allies (all imposing tariffs or penalties on unfair practices) might be more effective and less isolating. In fact, one notable element of President Biden’s approach has been to mend fences with allies that were strained by the prior tariff wars — for example, resolving the Boeing–Airbus subsidy dispute with the EU by suspending mutual tariffs, and replacing the blanket steel/aluminum tariffs on European allies with a quota arrangement to remove the tariff burden. These moves reflect an understanding that while tariffs can be a negotiating stick, long-term solutions often lie in negotiation and rulemaking (such as updating global trade rules on subsidies or technology). Thus, the centrist view attempts to reconcile the two extremes: accepting that unfettered free trade has downsides and that strategic tariffs have a role, but also upholding that the benefits of open trade and international cooperation are too significant to abandon. This camp often looks for evidence-based application — asking, for each proposed tariff: Will the benefits to the targeted sector demonstrably outweigh the costs to the broader economy and diplomatic interests? If yes, perhaps it’s justified; if not, alternatives should be pursued. In practice, this perspective aligns with using tariffs as one tool among many, to be used surgically and reviewed periodically for efficacy.

In sum, the tariff debate in America today is not black-and-white but a dialogue with many voices. From the fervent belief that tariffs are essential shields for the republic, to the counter-claim that they are self-defeating taxes, to the careful argument for using tariffs sparingly and smartly — these perspectives collectively shape how tariffs are understood and employed as instruments of domestic and foreign policy.

Broader Implications and Strategic Significance

The resurgence of tariffs in U.S. policy carries far-reaching implications for both the international system and America’s own strategic posture. In a broad sense, tariffs have become a kind of litmus test for the U.S.-led liberal order: their aggressive use by the United States in recent years signals a departure from the country’s traditional role as champion of free trade. This has raised questions about the future of the WTO-based multilateral trading regime. One key implication is the potential erosion of the WTO’s authority. The WTO operates on rules that discourage unilateral tariff actions (outside of narrowly defined exceptions). When the U.S. and others impose big tariffs citing national security or unfair trade without WTO approval, it undermines the credibility of the rules. Indeed, WTO dispute panels in 2020–22 found several U.S. tariffs (like the steel and aluminum duties) to violate agreements, only to have Washington pointedly refuse to remove them. U.S. officials have openly argued that the WTO is ill-equipped to handle the challenges posed by China’s state-capitalist model and that matters of essential national security are non-negotiable. In a 2022 statement after a WTO ruling, the U.S. Trade Representative’s office flatly declared it would “not cede decision-making over its essential security to WTO panels,” insisting the U.S. would keep its steel tariffs despite the ruling. The implication is stark: if the system’s biggest economic power bypasses the referee when convenient, other nations may do the same. We could see a drift toward a more power-based trading order, where might makes right and disputes are settled by tit-for-tat measures or regional blocs rather than impartial adjudication. Some experts argue we are already in a “post-WTO” era in practical terms, as evidenced by the U.S. paralysis of the WTO Appellate Body (by blocking new judge appointments) and the proliferation of ad hoc tariff wars and managed trade deals.

For American foreign policy, this turn to tariffs reflects a broader shift towards economic statecraft and strategic competition. Tariffs, export controls, and investment restrictions are now front-line tools in the geopolitical contest with China. Rather than viewing trade as purely an economic activity producing mutual gains, U.S. strategy increasingly frames trade in terms of dependencies and leverage. Tariffs have thus taken on a role akin to sanctions — a way to exert pressure without military force. This blurs the line between economic and security domains. For instance, the tariffs quadrupled in 2024 on Chinese electric vehicles and batteries were as much about slowing China’s technological edge and protecting a “critical sector for America’s future” as about trade per se. In effect, tariffs are being used to decouple certain supply chains from an adversary, steering them towards either domestic producers or trusted allies. If this strategy continues, we might witness a partial unwinding of globalization: a world where trade flows are reoriented along strategic lines (e.g., “friend-shoring” critical industries among allied democracies, while erecting barriers against rival powers). The implication for global trade is a possible bifurcation into blocs — a U.S.-led sphere with its own high-tech supply chain and a China-led sphere — with tariffs and export controls delimiting the two. Such fragmentation could reshape international relations, reducing interdependence (and the peace it arguably fostered) but also potentially creating more resilience within blocs.

Domestically, the normalization of tariffs portends a more interventionist economic policy. It indicates that U.S. policymakers are willing to put industrial policy above pure market liberalism. Tariffs, along with subsidies like the CHIPS Act for semiconductors or the Inflation Reduction Act’s clean energy incentives, are tools to actively shape market outcomes in favor of domestic capabilities. This reflects a strategic calculation that economic strength is the foundation of national power, and that unfettered free markets may not deliver the kinds of strength (e.g., manufacturing capacity, supply chain security, good jobs) that the nation needs. The return of tariffs has also forged unusual political coalitions, suggesting a realignment of traditional views. For example, many Republican lawmakers who once espoused free trade have embraced tariffs under populist influence, while some Democrats aligned with labor have also backed tariffs on the grounds of protecting workers. The common ground is economic nationalism, which has gained resonance among voters disillusioned by decades of deindustrialization. If public opinion continues to favor protecting home industries — polling in recent years shows growing skepticism of free trade — future administrations, whether Republican or Democrat, may find it politically expedient to maintain a tougher trade stance. Thus, the pendulum of U.S. trade policy may not swing back easily to the 1990s-era consensus. Instead, we could be entering a sustained period of managed trade: negotiations and deals will still happen, but they will be more transactional (focused on balancing accounts or carving out national advantages) rather than based on broad principles of multilateral liberalization.

Another broad implication is how other countries respond to the U.S. tariff stance. Allies in Europe and Asia have been adapting by seeking exemptions or new arrangements — for instance, the EU negotiated a truce whereby a certain quota of steel exports enters the U.S. without tariffs, and in return, the EU delayed its planned increase of retaliatory tariffs on American goods. This shows that tariff disputes can spur diplomatic resolutions, albeit often after a period of brinkmanship. On the other hand, rivals like China have doubled down on self-reliance strategies. China’s “dual circulation” policy is essentially a hedging strategy to rely more on its domestic market and indigenous innovation, in case access to U.S. markets or technology is curtailed. If every major power pursues self-reliance to an extreme, the integrated global economy could fracture, with efficiency losses and potential instability. However, some observers note a silver lining: the recalibration may lead to fairer trade practices in the long run. For example, U.S. pressure via tariffs has at least brought issues like intellectual property theft and excess industrial capacity to the forefront of international agendas (even the EU and Japan now acknowledge these concerns more openly). It is conceivable that tariffs are serving as a disruptive catalyst that will force reforms — either in China’s policies or in WTO rules — that wouldn’t occur otherwise. In that sense, the tariffs’ broader meaning might be as a wake-up call that the old trade architecture needs modernization to address new realities (state capitalism, climate change, etc.).

Within the field of international political economy, the U.S.’s tariff-centric turn has re-ignited debates over decoupling vs. interdependence. Are we safer when economies are entwined (making conflict costly), or does excessive interdependence create strategic vulnerabilities that adversaries can exploit? Tariffs sit at the heart of that debate: a tariff barrier can be seen either as insulating the nation from external risk or as dismantling the ties that bind nations in peace. The U.S. is currently tilting toward insulation in certain areas, reflecting a strategic choice that the risks of dependence (on China, for example) outweigh the efficiency gains of free trade. The coming years will likely further clarify this stance — perhaps through a new grand strategy of “economic security,” wherein tariffs, export bans, and allied supply chain pacts form a key pillar alongside military alliances. If tariffs are essential to this strategy, they may be used in novel ways, such as “selective tariff snapbacks” held in reserve by U.S. negotiators if partners do not honor commitments, or dynamic tariffs that adjust based on currency misalignments or emissions content. Each innovation would carry implications for the norms of international trade. The strategic framing of tariffs also means that decisions on tariffs will be made not only by economists, but by national security councils and strategic planners. In other words, trade policy may increasingly be treated as foreign policy.

Lastly, there’s an implication for the concept of globalization itself. Tariffs are a symbolic reverse gear on globalization’s engine. After decades where the assumption was that barriers only go down, now barriers are visibly going up among major economies. Businesses around the world have taken note: many are reconsidering long, just-in-time global supply chains that might be broken by sudden tariff hikes or trade wars. Some U.S. companies have shifted sourcing from China to other countries (Vietnam, Mexico) to mitigate tariff exposure, a process of supply chain diversification that could reshape global investment patterns. Meanwhile, foreign firms eyeing the U.S. market may invest in American production (to “build where you sell”) as a way to bypass tariffs — for instance, several Asian solar panel and electric vehicle companies have announced new U.S. factories in part to avoid current or anticipated import duties. If this trend continues, tariff policy will have influenced a partial re-localization of manufacturing, with all the attendant effects on labor, environment, and innovation systems. The world could see a modest retreat from the hyper-globalized model towards a more regionalized one. Importantly, this does not mean an end to trade — rather, trade flows may reorient (e.g., more U.S.–Mexico trade, less U.S.–China trade) and trade agreements might become more regional (like the USMCA replacing NAFTA, or the U.S. pursuing Indo-Pacific agreements that exclude China). In that context, tariffs are not the end of globalization but a force reshaping it into new patterns aligned with geopolitical affinities.

In sum, the contemporary use of tariffs by the United States carries significant meaning: it is at once a declaration of economic sovereignty, a signal of new strategic priorities, a test for the durability of international institutions, and a driver of change in how global commerce is organized. Tariffs, in reemerging as a policy of choice, are reminding the world that geopolitics and economics are deeply intertwined — and that the flows of trade can be as much subject to national strategy as to market forces.

Real-World Applications and Case Studies

To appreciate how tariffs function as a practical tool of U.S. domestic and foreign policy, it is illuminating to examine several real-world episodes across different domains. These cases demonstrate tariffs in action — their objectives, execution, and consequences — in concrete terms.

1. The U.S.–China Trade War: Perhaps the most consequential tariff action in recent history, the trade clash between the United States and China since 2018 showcases tariffs as both economic policy and geopolitical gambit. The U.S. launched this conflict with a Section 301 investigation into China’s intellectual property and technology transfer practices, concluding that China had engaged in unfair practices (forcing U.S. companies to hand over technology, cyber-theft of trade secrets, heavy subsidization of industries, etc.). In response, the Trump administration imposed an unprecedented series of tariffs on Chinese imports — by 2019, roughly $360 billion worth of Chinese goods (about two-thirds of U.S. imports from China) were subject to additional tariffs ranging mostly from 10% to 25%. These covered a vast array of products: steel, aluminum, machinery, electronics, furniture, apparel, and more — eventually, even consumer goods like laptops and toys were hit. The policy goal was multifold: pressure Beijing to end practices harmful to U.S. companies, reduce the bilateral trade deficit, and incentivize manufacturers to relocate supply chains out of China (ideally back to the U.S.). China retaliated in kind, levying tariffs on about $110 billion of U.S. exports, targeting sensitive sectors such as agriculture (soybeans, pork, fruits), automobiles, and aerospace. This tit-for-tat escalation rattled global markets and supply networks. American farmers found their largest export market (China) suddenly far less accessible — soybean exports to China dropped dramatically, leading the U.S. government to provide over $25 billion in aid to affected farmers in 2018–2019. Meanwhile, many U.S. import-dependent companies struggled with rising costs. For example, small electronics manufacturers faced 25% surcharges on components they sourced from China, squeezing their profit margins or forcing them to raise consumer prices.

Diplomatically, the tariff duel signaled a deepening rivalry. Yet it also brought China to the negotiating table. In January 2020, the two nations signed the “Phase One” agreement: China committed to purchase an additional $200 billion of U.S. goods over two years (including farm products, energy, and manufactured goods) and made some pledges to strengthen IP protection and curb forced tech transfers. In exchange, the U.S. suspended further tariff increases (some had been set to climb higher) and even cut the rate in half (from 15% to 7.5%) on a subset of approximately $120 billion in imports. However, crucially, the bulk of the tariffs remained in place even after the deal — roughly $250 billion of Chinese goods still faced 25% tariffs going into 2021, and China maintained its retaliatory tariffs too (though with exceptions for certain needed imports). The Phase One deal somewhat eased tensions but fell short of its targets — China ultimately did not fulfill the $200 billion purchase commitment (reaching only about 57% of the goal by the end of 2021). Structural issues like industrial subsidies or the role of state enterprises were left unresolved. Thus, when President Biden took office, he inherited a tariff-laden status quo. Notably, Biden chose not to lift the tariffs unilaterally, despite calls from some business groups and consumer advocates. Instead, the new administration reviewed the tariffs and decided they provided useful leverage and should be integrated into a broader strategy on China. By 2023–2024, the Biden administration even expanded tariffs in targeted tech sectors: for instance, doubling the duties on certain Chinese-made semiconductors to 25% and hiking tariffs on Chinese electric vehicles to a striking 100% effective rate. These moves aimed to buttress burgeoning U.S. high-tech and green industries against a “flood” of subsidized Chinese imports, and dovetailed with separate export controls that ban selling China the most advanced U.S. chips and chipmaking equipment. China, in turn, protested vehemently and warned of retaliation (which could include measures beyond tariffs, such as restrictions on exports of critical minerals like lithium or rare earth elements, where China holds leverage). The U.S.–China tariff war underscores how tariffs are being used as a long-term strategic tool: far from a temporary negotiating ploy, they have become a sustained means of economic containment and negotiation between great powers. Domestically, this application of tariffs has been a double-edged sword — it provided relief to some industries (e.g., U.S. steelmakers saw higher prices and profits for a time) and spurred some supply chain diversification, but also contributed to higher prices for consumers and strained sectors like agriculture and retail. Whether this cost is worth the strategic objectives remains hotly debated, making the China case an exemplar of the complexities inherent in wielding tariffs in pursuit of broad geopolitical goals.

2. Steel, Aluminum, and the Anatomy of Retaliation: In March 2018, the U.S. invoked Section 232 of the Trade Expansion Act of 1962 to impose tariffs of 25% on imported steel and 10% on imported aluminum, citing national security grounds. This case illustrates tariffs deployed in a more traditional protectionist mold (to aid a domestic industry) but on a global scale, and it provides a clear view of allied retaliation and subsequent negotiation. The tariffs were unusual because they applied to virtually all countries’ exports (initially, even close allies like Canada, Mexico, the EU, Japan, and South Korea), rather than targeting a specific country for unfair practices. The Commerce Department had reasoned that a healthy domestic metals sector was vital for defense needs and that imports (which accounted for roughly a third of U.S. steel consumption) were undermining that health due to global overcapacity, largely blamed on China. However, China itself accounted for only a small fraction of U.S. steel imports — the largest suppliers were U.S. treaty allies. These allies reacted with outrage and reciprocal measures. The European Union prepared a retaliatory tariff package hitting about €2.8 billion of U.S. exports, choosing politically symbolic products: Kentucky bourbon, Harley-Davidson motorcycles (iconic American brand), Levi’s jeans, orange juice, and various steel products. Canada, likewise, levied tariffs on $12.6 billion of U.S. goods, including steel, aluminum, and a range of consumer products (from ketchup to lawn mowers), dollar-for-dollar matching the steel/aluminum duties effect. Mexico targeted U.S. pork, cheese, and bourbon, among other goods. These counter-tariffs were designed not only to offset economic harm but to exert political pressure on U.S. leadership by hitting exports from key constituencies. The stage seemed set for a prolonged trade fight, even with allies.

However, these tariffs and counter-tariffs ultimately became catalysts for new trade understandings. With Canada and Mexico, the U.S. quickly leveraged the steel tariff issue during negotiations to replace NAFTA with the United States–Mexico–Canada Agreement (USMCA). In mid-2019, as part of USMCA’s finalization, the U.S. agreed to lift the metal tariffs on Canada and Mexico, and those countries likewise lifted their retaliatory duties. It was a recognition that sustaining barriers among close North American partners was counterproductive. The resolution involved setting up a monitoring mechanism to prevent Chinese steel transshipments through Canada/Mexico, instead of tariffs. With the European Union, resolution took longer but came with a strategic twist. In late 2021, the Biden administration struck a deal with the EU to pause the dispute: the U.S. converted its tariffs on EU steel/aluminum into a tariff-rate quota system (allowing a certain quantity to enter tariff-free, after which tariffs apply), effectively lifting the bite of tariffs on normal trade volumes. The EU, in return, suspended its retaliatory tariffs. Furthermore, the U.S. and EU announced they would work together on a “Global Arrangement on Sustainable Steel and Aluminum,” aiming by 2024 to form a club of nations that impose barriers on carbon-intensive (i.e., high-polluting) steel. This pointed to a novel use of tariff policy — linking it with climate policy to reward cleaner producers and penalize dirtier ones (in which China, with its coal-fired steel mills, would be disadvantaged unless it joins in carbon curbing). While the final form of this arrangement is still under negotiation, the concept shows tariffs being repurposed from a blunt protectionist instrument into a carrot-and-stick for international standards (clean manufacturing in this case). The steel episode demonstrates the retaliatory framework in action: when the U.S. imposed tariffs, partners retaliated as per WTO rules (since they viewed the U.S. action as a “safeguard” measure, they claimed the right to rebalance). Eventually, all parties found a compromise through new agreements, but not before real economic pain and political friction. Importantly, the U.S. faced legal challenges at the WTO for its Section 232 tariffs — and as noted earlier, a WTO panel ruled in 2022 that the U.S. tariffs violated trade rules (since it deemed the “national security” justification unconvincing). The U.S. simply ignored the ruling, reinforcing that in these real-world cases, power politics often trumps legal process. As a result, allied trust was tested; some argued the U.S. misuse of “security” as a rationale might encourage others (Russia, China) to do the same for their protectionism. On the other hand, one could argue the tactic did work to some extent: it secured a NAFTA update and brought Europe to the table to address a shared concern (China’s dirty overcapacity). Thus, the steel/aluminum case is a microcosm of tariffs’ double-edged nature — effective in drawing attention and leverage, yet costly and risky in the interim.

3. Tariffs and Trade Agreements — The USMCA Example: Tariffs also play a role as bargaining leverage in trade negotiations, as seen in the run-up to the USMCA in 2018. When the U.S. sought to renegotiate NAFTA, the Trump administration frequently brandished tariff threats to gain concessions. Beyond the steel tariffs on Canada and Mexico (discussed above), a dramatic instance was the threat of auto tariffs. The U.S. Commerce Department investigated whether imported automobiles threatened U.S. national security (under Section 232, the same statute used for steel). This alarmed NAFTA partners (as well as Japan and Germany) given the enormous auto trade. While the U.S. did not ultimately impose a blanket auto tariff, the credible threat of a 25% tariff on cars hung over talks and arguably gave the U.S. negotiating capital. In the final USMCA deal, Canada and Mexico agreed to tighter auto rules-of-origin (requiring a higher percentage of a car’s components to be made in North America to trade tariff-free) and to labor provisions that would raise Mexican auto workers’ wages. These provisions aligned with U.S. objectives of keeping more auto production in the U.S. or high-wage locales. Observers noted that the mere possibility of auto tariffs — which would have devastated the Canadian and Mexican car industries — helped push those countries to accept terms they might otherwise resist. Once the USMCA was signed, the U.S. suspended the auto tariff threat indefinitely for those partners. This exemplifies how tariffs can be used as a coercive negotiating tool short of actual implementation. It is a risky gambit (had talks failed, imposing auto tariffs on allies would have caused economic shock and legal challenges), but in this case, the gamble contributed to a diplomatic outcome. Furthermore, by including clauses in USMCA that mandate certain labor standards and limit members from signing free trade deals with “non-market” economies (a veiled reference to China), the U.S. used the agreement to indirectly isolate China — again employing trade arrangements in service of a broader strategy. Tariffs were the stick to get the carrot of a revised agreement; the new rules themselves function like selective trade barriers favoring the U.S. and its high-wage environment. The broader point is that tariffs and trade agreements are not opposites but can be sequential steps: tariffs generate leverage, leverage yields an agreement, and the agreement ideally locks in new rules that make tariffs unnecessary (until or unless one party cheats, in which case tariffs might snap back). USMCA’s successful conclusion (with overwhelming bipartisan approval in Congress) suggested a template for future U.S. trade strategy — harder-edged negotiation using tariffs if needed, and deals that emphasize managed trade outcomes (like quotas or specific export targets) rather than broad free-market access.

4. Unilateral Tariffs for Non-Trade Goals — The Mexico Immigration Standoff: A striking and somewhat unconventional application of tariffs occurred in mid-2019, when President Trump threatened Mexico with escalating across-the-board tariffs — starting at 5% on all goods and rising to 25% — unless the Mexican government took stronger action to curb the flow of Central American migrants crossing Mexico to reach the U.S. border. This episode is noteworthy because it divorced tariffs entirely from any trade complaint; instead, tariffs were wielded as a blunt foreign policy instrument to achieve a security/immigration objective. The threat sent shockwaves through supply chains (Mexico is one of the U.S.’s largest trading partners, deeply integrated, especially in the automotive, electronics, and agriculture sectors). A 25% tariff on all Mexican imports (which exceed $350 billion annually) would have been economically devastating for both nations, and businesses on both sides of the border lobbied furiously against it. Mexico’s leaders, facing this immediate existential threat to their economy, rushed to negotiate. Within days, Mexico agreed to significantly increase enforcement: deploying its National Guard to interdict migrants, expanding a program to keep asylum seekers in Mexico, and strengthening its own southern border controls. President Trump then “suspended” the tariff threat indefinitely, claiming victory by citing Mexico’s concessions. In essence, the U.S. extracted a non-trade policy change from a sovereign neighbor by leveraging tariffs. Critics at the time argued this set a dangerous precedent — that the U.S. was willing to upend lawful trade and weaponize tariffs for essentially any policy demand. Legally, Mexico likely could have challenged such tariffs at the WTO (since immigration control has nothing to do with trade and thus the tariffs would be plainly in violation of WTO commitments). But practically, the immediacy of harm forced Mexico’s hand before any legal process could unfold. This real-world case underscores that tariffs can operate as geopolitical bargaining chips well beyond the trade realm. It also foreshadowed later musings (by Trump and others) that tariffs could be a general-purpose tool — for example, some have floated tariff hikes on adversaries for human rights abuses or as punishment for aggressive military actions, akin to sanctions. However, using tariffs this way blurs international economic policy with diplomacy and raises questions of reliability: it signals to allies that trade relations can be hijacked by unrelated disputes, thereby eroding trust. Indeed, one could argue that the U.S. threatening Mexico’s economy in this manner sowed some mistrust, even as it achieved a short-term tactical goal on migration. From Mexico’s perspective, acquiescing may have been the only viable choice, but it surely reinforced their awareness of asymmetric power and the need to diversify economic ties to not be overly dependent on the U.S. market. This case serves as a caution that while tariffs can “work” quickly as leverage, they may carry long-term diplomatic costs. It also shows how the domestic political appeal of tariffs can drive their use: cracking down on immigration was a key issue for Trump’s base, and the tariff threat was a dramatic gesture to show action. In the end, it did lead to a deal, which the administration touted as a foreign policy win achieved without firing a shot — only firing off a tariff threat.

5. Tariffs in Technology and Supply Chain Realignment: As the U.S. enters into competition in high-tech sectors, tariffs have been selectively applied to influence supply chain decisions. One example is the solar panel industry. In 2018, the U.S. imposed safeguard tariffs on solar panels (and washing machines) under Section 201 of the Trade Act, due to a surge of imports that threatened domestic producers. Most solar import tariffs hit Chinese-made panels (China dominates global solar manufacturing), but they also apply to any country’s panels above a certain import quota. The aim was to give a breathing space for U.S. solar module manufacturers against a flood of ultra-cheap imports (often from Chinese firms that had relocated to Southeast Asia to evade earlier tariffs). The short-term effect was higher prices for solar installers and a mix of outcomes: a couple of new U.S. solar factories opened or expanded (some foreign firms set up small plants in the U.S.), yet the installation side of the industry complained of job losses due to costlier panels. The tariffs stepped down from 30% initially to 15% over four years and were scheduled to expire in 2022. However, the Biden administration extended them for another four years (with an exemption for bifacial panels needed for large-scale projects). This extension signaled that even a president pushing aggressive climate goals saw a role for tariffs to ensure not all the benefits of the clean energy boom accrue to China. The subtext is that tariffs can buy time for industrial development at home, but that time must be used wisely; otherwise, one just ends up with permanent tariffs and a still-uncompetitive industry. The jury is still out on whether U.S. solar manufacturing will significantly expand under this shield, but the policy shows a commitment to trying. Similarly, in semiconductors, while the main U.S. approach has been export controls on China and domestic subsidies (the CHIPS Act), tariffs have been part of the mix too. The U.S. maintains tariffs on certain Chinese-made semiconductors and related equipment, again to support domestic producers and push companies to source from allies (Taiwan, South Korea, Japan) instead. An illustrative case in supply chain recalibration is that of Taiwanese electronics giant Foxconn: after facing U.S. tariffs on Chinese-assembled electronics, Foxconn and other firms began shifting some assembly of products like servers and telecom equipment from China to Taiwan or Mexico to avoid U.S. import duties. Likewise, Japanese and South Korean companies have considered moving production of appliances and other goods into the U.S. or Mexico to sidestep tariffs and be closer to the market. These micro-level decisions, aggregated, begin to reshape how global supply chains function — essentially a partial unwinding of the China-centric manufacturing hub model. Tariffs are not the sole driver (companies also worry about China’s rising wages and geopolitical tensions), but they are a tangible factor tipping cost calculations. Friendshoring — relocating production to countries deemed politically reliable — is being incentivized by both sticks (tariffs on adversary-linked imports) and carrots (free trade agreements or preferences with allies). A real-world manifestation is the Biden administration’s discussion with allies about creating “trusted supplier” networks for critical products, where members might get tariff-free treatment while outsiders face tariffs. For instance, the U.S. has broached the idea of a minerals alliance for battery materials to ensure EV supply chains run through friendly nations. Should such arrangements solidify, tariffs (or their absence) become an enforcement mechanism distinguishing insiders from outsiders in the new economic blocs.

6. WTO-Approved Retaliatory Tariffs — The Boeing/Airbus Saga: Lest one think tariffs are solely an American initiative, it’s worth noting a case where tariffs were used by both the U.S. and EU under WTO authorization: the long-running Boeing vs. Airbus aircraft subsidies dispute. After years of litigation, the WTO ruled that both the EU and the U.S. had given illegal subsidies to their respective aircraft champions. Consequently, in 2019, the WTO permitted the U.S. to impose tariffs on about $7.5 billion worth of EU exports annually — the largest such authorization in WTO history at that time — to compensate for Airbus subsidies. The U.S. promptly did so, slapping 10% tariffs on imports of Airbus aircraft and 25% tariffs on a range of other items, including French wines, Scotch whisky, Italian cheese, Spanish olives, and British woolen suits. Europe felt the pinch, especially its luxury goods and agriculture sector, which was targeted for maximum political effect. Then, in late 2020, the WTO, in a parallel case, allowed the EU to impose tariffs on $4 billion of U.S. goods due to Boeing subsidies. The EU went ahead with its own 15% tariff on Boeing planes and 25% on U.S. products like tractors, sweet potatoes, orange juice, and condiments. This rare instance of sanctioned tariff retaliation shows that even under rules, tariffs remain a favored tool to pressure compliance and extract a settlement. Indeed, by early 2021, with both sides suffering, the U.S. and EU agreed to suspend these mutual tariffs and later reached a five-year truce in the aircraft dispute, aiming to negotiate a longer-term resolution on permissible subsidies. The removal of these tariffs was a relief to industries on both sides and demonstrated how tariffs can be turned off as quickly as on when a deal is struck. It also highlighted that tariffs, when authorized by the WTO, are supposed to prod the offending party to remove the illegal subsidy. In trade lore, this is how the system “enforces” rules — through tit-for-tat pain until compliance. However, the Boeing/Airbus case revealed the limitations of that approach: the disputes dragged on for over a decade, and even when tariffs were finally authorized, they harmed innocent bystander industries that had nothing to do with aerospace (like Scotch whisky exporters losing sales in the U.S.). It underscores an often-raised counterpoint: tariffs are a blunt enforcement tool. Nevertheless, they sometimes succeed where diplomatic pleas do not. In this case, the looming threat of indefinite tariffs on iconic products helped bring both parties back to negotiation and, hopefully, toward disciplining future aerospace subsidies in tandem rather than unilaterally.

Through these examples, a common thread emerges: tariffs are versatile in application — from negotiating cudgel, to defensive shield, to punitive measure — but they always create a web of effects, intended and unintended. They can achieve results (a new agreement, a policy change, a momentary industry boost) but typically at a cost (higher prices, strained relations, retaliatory damage). Thus, in real-world practice, U.S. policymakers have treated tariffs somewhat like high-stakes leverage: best used when the stakes justify the collateral damage and when paired with a clear endgame or off-ramp. In the contemporary context, tariffs have arguably become essential in that they are now a permanent fixture of the U.S. policy toolkit, employed in realms from economic rebalancing to national security. Even as debates continue about their efficacy, the United States in the 2020s has demonstrated that it is willing to bear the short-term costs of tariffs for what it perceives as longer-term strategic gains. For better or worse, the tariff tool is back on the table in American statecraft — and likely to remain so as the nation navigates a challenging global landscape of competition, conflict, and cooperation.
