The foundational architecture of United States global power is facing an unprecedented internal challenge, driven not by distant geopolitical rivals, but by the Trump administration’s adversarial approach toward its immediate neighbors, Canada and Mexico. Throughout modern history, maintaining friendly relations with contiguous neighbors has served as a cornerstone of American security, fostering mutual economic prosperity and providing a secure platform to address complex transnational challenges. Geopolitical reality dictates that weak neighbors often export trouble, while strong partners enhance stability. Today, however, that dynamic has been severely disrupted. In Canada, President Donald Trump’s implementation of high tariffs and repeated dismissive rhetoric framing the country as a "51st state" are widely perceived as direct assaults on national economic sovereignty and independence. Meanwhile, south of the border, economic coercion and overt threats of military intervention from Washington have successfully revived deep-seated historical anxieties in Mexico concerning traditional American hegemony.
This robust North American partnership was not forged overnight; it required generations of delicate diplomacy and strategic alignment. During the nineteenth century, the foreign policy of the United States remained predominantly focused on its home continent, a theater where Washington fiercely competed for territorial dominance against France, Mexico, Russia, Spain, the United Kingdom, and various indigenous nations. However, as the United States ascended to the status of a global superpower over the course of the twentieth century, subsequent generations of American strategists increasingly took North American relations for granted. Washington systematically shifted its primary diplomatic and military attention toward Europe, the Asia-Pacific, and the Middle East.
It was not until the closing years of the Cold War that successive U.S. presidents began to seriously recognize the critical necessity of reinvesting in the North American continent. Ronald Reagan famously articulated this strategic rationale when launching his presidential campaign in 1979, declaring that the key to future American security lay in ensuring Canada and Mexico became significantly stronger economically and politically. Reagan emphasized that it was past time for the United States to stop treating its nearest neighbors as mere foreigners.
Geopolitics fundamentally begins with geography, and the geographic position of the United States grants it an extraordinary, unmatched advantage over every other major global power. China and Russia, for example, must constantly manage fraught relationships with 14 distinct neighbors each, many of whom harbor lingering resentments stemming from long histories of territorial conflict. India must navigate six immediate land borders, including one shared with a nuclear-armed rival. Furthermore, the global trade access and maritime mobility of all three powers heavily depend on navigating vulnerable maritime chokepoints.
By stark contrast, the United States shares long, secure borders with two benign, democratic neighbors while enjoying open, unhindered sailing across two vast oceans. Close, cooperative engagement with Canada and Mexico fundamentally underpins homeland security, attracts robust foreign and domestic investment, drives technological innovation, and sustains a massive shared market rich in natural resources and human talent. This trilateral alignment is essential for effectively combatting transnational criminal networks, managing orderly migration, and protecting shared environmental assets such as clean air, water, and wildlife habitats.
Consequently, a safe, resilient, and adaptive North America has long served as the indispensable starting point for overall U.S. global strategy. Washington is inherently best positioned to navigate an unpredictable and uncertain world when the United States, Canada, and Mexico present a unified, common front. Yet, the current trajectory of bullying and economic coercion is actively driving these natural partners away. In doing so, the administration is dismantling a uniquely precious geopolitical asset: a strong, secure continental base from which Washington has historically projected its international power.
Continental Vision
The historical realization that strong, amicable relations with immediate neighbors would directly amplify global influence first took root with William Seward, who served as U.S. secretary of state from 1861 to 1869. Seward firmly asserted that gaining control of the North American continent was synonymous with becoming the controlling interest in the entire world. When negotiating the historic purchase of Alaska in 1867, Seward observed that the acquisition of Alaska and the Aleutian Islands extended a friendly hand directly toward Asia. During the same era, he actively pursued the acquisition of Greenland, Iceland, the Hawaiian Islands, and various strategic territories in the Caribbean, believing these outposts would effectively secure the oceanic approaches to the United States.
Seward astoundingly recognized, however, that the United States could dramatically increase its power through the cultivation of economic integration rather than through territorial conquest. He deeply abhorred European imperial conquests of foreign lands and had actively opposed the 1846–1848 Mexican-American War. At the conclusion of the American Civil War in 1865, Seward successfully prevented Generals Ulysses S. Grant and Philip Sheridan from launching an invasion of Mexico to depose the Habsburg archduke whom the French government had installed as emperor. Seward reasoned that an outright military invasion would inevitably ignite fierce Mexican hostility, and that the Mexican people were entirely capable of deposing the foreign interloper themselves—a prediction that materialized precisely as anticipated in 1867.
Seward navigated relations with the northern neighbor through similarly diplomatic channels. In 1867, the British government officially united its various North American colonies to form the Canadian Confederation, driven in part by a desire to deter a potential U.S. invasion of Canada in retaliation for London’s covert assistance to the Confederacy during the Civil War. Seward responded by deliberately choosing the peaceful path of international arbitration to resolve wartime claims against the United Kingdom.
Ultimately, Seward envisioned a North American union brought into existence through free choice, mutual consent, and commerce rather than through coercion or military conquest. He firmly believed in the innate attractive power of American society and institutions. Commerce, he maintained, would serve as a modern god of boundaries, organically redrawing geopolitical lines and drawing sovereign nations closer together. Ernest Paolino, his biographer, famously termed this foundational foreign policy concept Seward’s "law of imperial gravity."
The simultaneous restoration of Mexican President Benito Juarez and the formation of the Canadian Confederation in 1867 offered a promising horizon of a democratic North America bound together by increasingly close economic ties. While peaceful relations were successfully established among the neighbors, Seward’s grand continental vision steadily faded over subsequent decades as American policymakers redirected their sights westward, paying markedly less attention to the nations situated immediately to their north and south.
A Search for Stability
By the dawn of the twentieth century, the United States had grown accustomed to taking continental harmony entirely for granted. That complacent sense of security was abruptly shattered by the outbreak of the Mexican Revolution in 1910. Over the ensuing decade of violent internal conflict, frequent cross-border raids on American towns and the arbitrary seizure of U.S. property by various revolutionary factions and bandits compelled Washington to dispatch two separate military expeditions into Mexican territory.
Washington narrowly managed to avoid becoming bogged down in a protracted military quagmire. President Woodrow Wilson’s successful 1916 reelection campaign slogan, "He kept us out of war," referred just as much to the volatile situation in Mexico as it did to the unfolding catastrophe in Europe.
The persistent instability on the southern doorstep left the United States acutely vulnerable to foreign interference. In 1917, imperial Germany transmitted a secret proposal of alliance to the newly established Mexican government—a notorious communication intercepted by British intelligence—which promised robust German financial and military assistance aimed at helping Mexico recover the territories of Arizona, New Mexico, and Texas should Mexico side with Berlin in the event of a U.S. entry into World War I.
Over the following decades, the United States managed to stabilize diplomatic relations with the one-party authoritarian state that successfully consolidated political control in Mexico during the 1920s. As political scientist Pamela Starr has observed, Washington effectively accepted its neighbor’s internal autonomy, but strictly "within limits." So long as Mexican governance did not directly threaten U.S. security interests, Washington refrained from interference. Ensuring domestic stability in Mexico was deemed vastly more important than challenging its stunted democratic institutions, prickly nationalism, and largely closed economy.
This pragmatic arrangement endured for roughly half a century, during which both nations found functional ways to cooperate. Between 1942 and 1964, for instance, the U.S. Bracero Program successfully issued guest worker permits to approximately 4.6 million Mexican laborers, effectively filling critical domestic labor shortages in American agriculture, railway maintenance, and other heavy industries.
Concurrently, the twentieth century witnessed Canada’s steady political transition from a British dominion into an autonomous North American partner and vital global ally. Throughout the 1920s and 1930s, the United States and Canada constructed strategic bridges and tunnels designed to facilitate expanding economic exchanges. U.S. Secretary of State Cordell Hull subsequently negotiated highly significant reciprocal trade agreements with Canada in 1935 and 1938.
Following the conclusion of World War II, Canadian forces fought shoulder-to-shoulder with American troops in the Korean War and vigorously supported the institutional establishment of NATO, the General Agreement on Tariffs and Trade, the United Nations, and the broader architecture of the postwar international order. During the 1950s, the two nations jointly constructed the St. Lawrence Seaway and established an expansive continental radar defense system designed to monitor potential Soviet missile threats traversing the Arctic Circle. In 1965, they cemented their economic partnership by signing a historic pact creating a duty-free, integrated automotive market.
Ties That Bind
The pace of North American economic and strategic integration accelerated dramatically during the Reagan administration. Reagan’s warm diplomatic outreach to Canadian Prime Minister Brian Mulroney encouraged Mulroney to propose an ambitious, comprehensive free trade agreement in 1985. Mulroney took a substantial political risk: the Canadian public remained deeply wary of becoming economically dependent on or dominated by the United States, yet they simultaneously recognized the need for enforceable rules to discipline U.S. trade practices and attract foreign investment. The two governments successfully concluded the agreement in 1987, and the U.S. Congress approved the pact the following year, transforming the 1988 Canadian general election into an effective referendum on free trade—one that Mulroney ultimately won.
Meanwhile, Carlos Salinas, who assumed the Mexican presidency in 1988, recognized that a similar bilateral trade pact could fundamentally open up his country’s protected economy and attract much-needed foreign investment. Mexico was struggling under the weight of severe debt crises, declining energy revenues, and the systemic breakdown of the ruling party’s decades-old corporatist economic model, which had long fostered a centralized and closed economy. Seeking an escape from prolonged economic stagnation and a catalyst for domestic reform, Salinas took the bold step of formally proposing a comprehensive free trade agreement to U.S. President George H. W. Bush in 1990.
Canada formally joined the ongoing trade negotiations in 1991, and representatives from all three nations ultimately signed the landmark North American Free Trade Agreement (NAFTA) in 1992. For Washington, NAFTA represented a development of profound strategic significance that extended far beyond traditional trade metrics. It marked a major, historic step toward genuine reconciliation with Mexico, a nation that had remained deeply wary of the United States ever since losing nearly half its sovereign territory in the war that concluded in 1848.
Mexico was now explicitly looking to the United States to help accelerate its sweeping economic, social, and political transformation. Mexican negotiators hoped to import a predictable rule of law through robust legal protections for foreign investment, fair market competition, and intellectual property. Simultaneously, domestic reformers sought institutional inspiration from U.S. and Canadian democratic models as they built a competitive multiparty democracy and a more open society.
President George H. W. Bush viewed NAFTA as an indispensable cornerstone of overarching U.S. post-Cold War strategy, explaining in 1992 that the accord marked the beginning of a transformative new era and formed part of a new world order designed to help the United States prepare for the complex challenges and economic opportunities of the twenty-first century. The Bush administration firmly believed that the trilateral partnership would simultaneously deliver tangible economic dividends and pave the way for seamless continental cooperation on foreign policy, environmental protection, immigration management, and anti-narcotics enforcement. Unlike the European Union’s model of pooled sovereignty, economic integration via NAFTA was carefully structured to strictly respect national sensitivities concerning ultimate independence and sovereignty.
Bush’s successor, President Bill Clinton, successfully navigated the intense political challenge of securing congressional approval for NAFTA, accomplishing the legislative feat with robust bipartisan support from Republicans. Clinton deepened Washington’s long-term commitment to the North American project by extending a massive financial stabilization loan to Mexico during the 1995 peso crisis to prevent severe economic instability from spilling across the border into the United States. Furthermore, in the turbulent aftermath of the September 11 terrorist attacks, amid widespread fears that heightened security concerns would paralyze cross-border commerce, President George W. Bush launched specialized bilateral initiatives designed to ensure the safe and expedited transit of commercial cargo vehicles across both the Canadian and Mexican borders.
Better Together
Although vocal opponents of NAFTA argued vociferously that American workers would lose countless jobs to Mexican laborers willing to accept significantly lower wages, those apocalyptic economic predictions failed to materialize. Instead, the agreement proved to be an overwhelming economic and strategic success. By 2000, six years after NAFTA officially took effect, the U.S. unemployment rate dipped to 3.8 percent, hitting its lowest level in decades. Core inflation fell, national productivity rose, and real wages experienced steady growth, accompanied by notable gains for low-wage American workers.
The pact stimulated massive capital investment in interconnected railways, energy pipelines, electrical grids, and modernized border facilities that rendered continental supply chains remarkably efficient, particularly within the manufacturing sector. Total bilateral trade in goods and services between the United States and Canada surged from $169 billion in 1988 to approximately $900 billion by 2024. Concurrently, U.S.-Mexican trade skyrocketed from less than $100 billion prior to NAFTA to nearly $1 trillion.
Cross-border direct investment has heavily fueled this unprecedented economic expansion. U.S. direct investment stock in Canada climbed from $61 billion before NAFTA to roughly $750 billion, while Canadian direct investment inside the United States grew from $27 billion to approximately $500 billion. American direct investment in Mexico similarly jumped from $15 billion to a range between $130 billion and $150 billion, while Mexican corporate investments in the United States expanded from $1 billion to between $40 billion and $50 billion.
The United States currently serves as the origin point for as much as 60 percent of Canada’s imports and roughly 40 percent of Mexico’s imports. Consequently, when their respective economies expand and their corporate and household consumers purchase more foreign goods, the domestic U.S. economy benefits substantially. Economic growth in more distant, overseas economies rarely yields comparable returns for American exporters; when China increases its overall imports, for instance, the United States captures only six to seven cents of every additional dollar spent.
The original architects of NAFTA also harbored high hopes that the trade accord would foster robust economic opportunities within Mexico, enabling prospective workers to find gainful employment locally rather than undertaking dangerous migrations northward. Due to chronic economic difficulties in the preceding decades, the population of Mexican-born immigrants residing in the United States had climbed dramatically from roughly 760,000 in 1970 to approximately nine million by 2000. By 2010, however, net migration from Mexico had fallen to zero, with the vast majority of arriving migrants originating from Central America and points beyond, transforming Mexico into an essential, collaborative partner in helping Washington enforce its southern border immigration laws.
Although Donald Trump repeatedly vowed to scrap NAFTA entirely during his initial presidential campaign, the pact had by then become far too valuable to the North American economy to abandon outright. His administration ultimately settled for a renegotiated framework, replacing NAFTA with the United States-Mexico-Canada Agreement (USMCA) in 2020. While the updated accord modernized important regulatory provisions concerning digital commerce and established formal investigative procedures for labor complaints, its complex, protectionist rules of origin for regional automotive producers ultimately undermined the global competitiveness of the North American auto sector. Additionally, the new agreement weakened protections for foreign investors operating within Mexico, thereby eroding international confidence in the local rule of law.
Repairing the Rift
Although the USMCA formally remains in effect until 2036, the foundational concept of a cooperative North American partnership is presently on life support. The current U.S. administration declined to approve a routine extension of the trade pact out to 2042, introducing profound regulatory uncertainty that actively discourages long-term capital investment in both Canada and Mexico.
An even more acute challenge stems from the administration’s persistent desire to reserve the unilateral freedom to ignore established treaty obligations whenever politically expedient. Throughout 2025 and 2026, Washington imposed steep tariffs on Canadian automobiles, steel, aluminum, iron, metal-intensive manufacturing equipment, lumber, and pharmaceutical products, absurdly claiming that these trusted imports posed an immediate threat to U.S. national security. Given that the United States has actively championed the deep industrial integration of those specific economic sectors for more than 70 years, and that Canada has stood as a steadfast military ally for over a century, the national security designation shocked and deeply insulted Canadians.
The systematic weakening, or potential outright fracture, of U.S. diplomatic and economic ties with Canada and Mexico would constitute an unmitigated strategic disaster. Combined, the sovereign assets of the three contiguous democracies make North America an unmatched global powerhouse. Stretching from the frozen expanse of the Arctic almost to the tropics, the continent is home to nearly half a billion people, and unlike most advanced industrialized economies, their populations continue to experience positive demographic growth.
The region boasts a highly skilled labor force, fully integrated physical infrastructure, and world-class capacities in competitive agriculture, mining, heavy manufacturing, and specialized services. Furthermore, North Americans enjoy unparalleled access to cutting-edge emerging technologies, abundant financial capital, absolute energy self-sufficiency, and expansive production capacities spanning traditional oil and natural gas alongside renewable energy sources.
This represents an extraordinarily enviable geopolitical hand to play—not one that Washington should casually discard. Policymakers must cease antagonizing Ottawa and instead pivot immediately toward active cooperation with Canada on vital Arctic and maritime security, critical mineral extraction, and joint technological innovation. Canada’s world-class artificial intelligence talent, premier research capabilities, and vast natural energy reserves directly complement the strategic needs of the United States, exactly as its natural resources and industrial manufacturing did throughout the twentieth century.
Simultaneously, Washington must commit to assisting Mexico in fully realizing its vast domestic potential. While NAFTA successfully helped Mexico construct sophisticated economic institutions and cultivate a freer civil society, pervasive corruption continues to plague state and local governments, legal institutions, municipal police forces, and educational systems. Millions of Mexicans remain trapped working within the vulnerable informal economy, while ruthless drug cartels and transnational criminal syndicates routinely exploit institutional weaknesses.
By providing robust intelligence sharing and advanced technological support, the United States can empower Mexico to dramatically improve domestic security and strengthen the rule of law. Fostering stronger, more trustworthy public institutions will accelerate sustainable economic growth and transform Mexico into an even more capable and reliable regional partner.
From the pioneering vision of William Seward to the statesmanship of Ronald Reagan, the Bushes, and Bill Clinton, successive generations of American leaders have consistently recognized that a strong, secure North America provides the United States with an indispensable strategic anchor in an inherently uncertain world. While a zero-sum, transactional approach to international economics places current leadership outside this distinguished circle of strategic thinkers, the next U.S. administration will possess a vital opportunity to reverse course. To restore and successfully expand a constructive continental partnership, the United States must revive its traditional powers of attraction and treat its indispensable neighbors with mutual respect.
