- Trump’s renewed focus on the Western Hemisphere marks a significant departure from decades of U.S. disengagement.
- China’s strategic inroads in Latin America highlight rising security threats.
- Hemispheric defense is revived, reflecting historical U.S. strategic priorities
Donald Trump’s bold foreign policy shift, marked by sharp rhetoric and sweeping pronouncements, represents a decisive realignment of U.S. geopolitical strategy in the Western Hemisphere. His transition period alone made it clear that the era of American passivity in its own neighborhood is over. Trump’s vocal interest in strategic assets like the Panama Canal and Greenland, coupled with key appointments focused on Latin America and the southern border, underscores a broader reprioritization of regional security and trade.
This shift represents a significant departure from decades of neglect by previous administrations. While past presidents of both parties have turned their focus to conflicts in the Middle East and South Asia, Trump’s approach revives the long-standing tradition of American hemispheric defense. His prioritization of the U.S.-Mexico border, trade relations with Canada and Mexico, and renewed emphasis on strategic locations like Greenland are all elements of a broader policy aimed at reasserting American influence in the Western Hemisphere.
Historically, the United States viewed the Western Hemisphere as a critical theater for its strategic interests. The Monroe Doctrine of 1823 famously sought to exclude European powers from interfering in the region. From the purchase of Alaska under William Seward to the construction of the Panama Canal, American leaders treated their hemisphere as a vital sphere of influence. During World War II, Washington’s hemispheric defense policy, spearheaded by Nelson Rockefeller, included occupying Greenland and enlisting regional allies like Brazil and Mexico to support the Allied cause.
However, in recent decades, U.S. attention drifted elsewhere. Starting with President Jimmy Carter’s decision to cede control of the Panama Canal, American policymakers increasingly viewed their own hemisphere through the lens of past policy missteps. Episodes of U.S. intervention, from Cold War coups to early 20th-century gunboat diplomacy, became symbols of imperialism rather than strategic necessity. As a result, many U.S. leaders retreated from active engagement, unwilling to confront historical narratives or assert American influence.
Strengthening North America: The Need for a Unified Approach to Economic Competition with China
The post-9/11 era saw Washington consumed by counterterrorism and prolonged military engagements in Iraq and Afghanistan. The Western Hemisphere, perceived as stable and secondary, was largely ignored. But while the United States remained distracted, geopolitical adversaries filled the vacuum. China, for example, expanded its trade with Latin America thirty-five-fold since 2000. Today, it is the largest trade partner for many of the region’s major economies. More than twenty countries have joined China’s Belt and Road Initiative, giving Beijing significant economic and political leverage.
China’s strategic inroads are not limited to trade. It has invested in deep-water ports across seventeen countries and dominates regional telecommunications infrastructure—developments that pose serious security concerns. Chinese influence now extends to critical assets like the Panama Canal, where Beijing’s control over key operations has raised alarms in Washington. In Cuba, China’s upgraded intelligence facilities operate just ninety miles from U.S. shores. Chinese fentanyl, a key driver of America’s opioid crisis, flows through Mexican cartels into the United States, fueling a deadly epidemic.
Russia, though weakened, continues to play Cold War-style games in the hemisphere. It props up authoritarian regimes in Cuba and Venezuela, deploys warships to the Caribbean, and foments instability. Meanwhile, Iran and its proxy Hezbollah maintain a foothold in Latin America, and transnational criminal organizations thrive. These threats underscore the region’s enduring importance to U.S. national security.
Trump’s foreign policy reorients America’s focus back to its own hemisphere, advocating for a strategy rooted in historical precedent. By elevating immigration control and border security to central issues, he links domestic and foreign policy under a unified national security framework. His appointments—including a special envoy for Latin America, ambassadors with regional expertise, and White House advisor Stephen Miller—signal a commitment to institutionalizing this approach.
Greenland again tells Trump it is not for sale
Critics argue that Trump’s rhetoric and policies risk alienating allies and oversimplifying complex geopolitical dynamics. Yet his broader vision—a revival of hemispheric defense—is a return to foundational U.S. strategic thinking. Presidents from John Quincy Adams to Theodore Roosevelt recognized the necessity of securing the Western Hemisphere to safeguard American interests. Trump’s unapologetic emphasis on U.S. leadership challenges the narratives of imperial overreach that have long hampered proactive engagement.
As great-power competition intensifies, the Western Hemisphere will play an increasingly pivotal role in global strategy. China’s deepening influence, Russia’s provocations, and the persistent threat of transnational crime demand a robust U.S. response. Trump’s policy framework, if sustained and refined, could enhance U.S. security, strengthen trade partnerships, and counter growing regional threats more effectively. By reinvigorating a tradition of hemispheric defense, Trump positions the United States to counter emerging threats and secure its strategic future. This recalibration may well prove one of his most enduring geopolitical legacies.
