The United States, under the Trump administration, is dramatically reshaping its security posture in the Americas. Secretary of War Pete Hegseth unveiled the “Greater North America” strategy this week, extending Washington’s security perimeter to encompass all nations north of the equator – from Greenland to Guyana – and signaling a shift in responsibility for southern hemisphere security. This move, presented at the U.S. Southern Command in Florida, has significant implications for regional alliances and global power dynamics.
This isn’t simply a redrawing of lines on a map. It’s a fundamental recalibration of how the U.S. Views its sphere of influence and, crucially, who bears the burden of maintaining stability. Here is why that matters. For decades, the U.S. Has operated under a broad, often loosely defined, security umbrella across the Western Hemisphere. Now, Washington is explicitly delineating a “north” and “south,” with different expectations for each.
Defining the New Perimeter: Geography as Destiny
Hegseth’s rationale centers on geography. He argues that natural barriers – the Amazon rainforest and the Andes Mountains – effectively separate the strategic concerns of the northern and southern regions. This isn’t a new idea, of course. Geopolitics has always been deeply intertwined with terrain. But the formal articulation of this division, and the explicit linkage to security responsibilities, is a significant departure. The administration believes that countries north of the equator share common interests and face similar threats, justifying a more integrated security approach.
The “Greater North America” concept, as presented, isn’t about outright annexation or domination. It’s about coordination and a perceived “burden sharing.” The U.S. Intends to bolster its military presence throughout the hemisphere, but expects its partners to step up as well. But there is a catch. This expectation of increased responsibility extends beyond military spending. It encompasses safeguarding critical infrastructure and resources – a point that raises questions about potential economic leverage.
Venezuela’s Inclusion and the Shifting Regional Landscape
The inclusion of Venezuela within this “Greater North America” perimeter is particularly noteworthy. Despite strained relations and ongoing political turmoil, the administration views Venezuela as strategically vital, likely due to its vast oil reserves and proximity to key shipping lanes. This doesn’t necessarily signal an immediate thaw in diplomatic relations, but it does suggest a pragmatic reassessment of Venezuela’s role in regional security.
This move is already prompting reactions across Latin America. Some nations may view it as a welcome sign of increased U.S. Engagement, while others will likely see it as an attempt to reassert American hegemony. Brazil, for example, with its significant military capabilities and growing regional influence, may be wary of being relegated to a secondary role in hemispheric security. The Atlantic Council has published analysis suggesting that this strategy could exacerbate existing tensions between the U.S. And countries pursuing more independent foreign policies.
A Historical Echo: The “Fourth Sphere Defense”
Hegseth’s invocation of “Defensa de la Esfera Cuarta” – “Fourth Sphere Defense” – is a fascinating historical reference. He drew parallels to World War II, when the U.S. Navy actively patrolled and protected vital shipping lanes against submarine threats. This suggests a willingness to employ a more assertive, even interventionist, approach to safeguarding American interests in the region. It’s a clear signal that the administration is prepared to utilize all available tools – military, economic, and diplomatic – to maintain its security perimeter.
This echoes a broader trend in U.S. Foreign policy: a renewed emphasis on great power competition and a willingness to challenge perceived adversaries. The Biden administration, while adopting a different tone, has largely continued many of the Trump-era policies focused on countering Chinese influence in the Western Hemisphere.
The Economic Ripples: Supply Chains and Investment Flows
The “Greater North America” strategy isn’t solely a military or political undertaking. It has significant economic implications. Increased security cooperation could lead to greater stability, which in turn could attract foreign investment and boost economic growth. However, the emphasis on safeguarding critical infrastructure and resources could also lead to increased protectionism and restrictions on trade.
Here’s a look at the defense spending of key nations in the region, illustrating the potential for increased military investment:
| Country | 2023 Defense Budget (USD Billions) | % of GDP |
|---|---|---|
| United States | 886 | 3.2 |
| Brazil | 34.8 | 1.8 |
| Colombia | 11.5 | 2.8 |
| Mexico | 8.3 | 0.8 |
| Venezuela | 2.5 (estimated) | 1.5 (estimated) |

The potential for supply chain disruptions is also a concern. The Panama Canal, a critical artery for global trade, falls squarely within the “Greater North America” perimeter. Any instability in the region could disrupt shipping lanes and lead to higher transportation costs. The focus on securing resources could lead to increased competition for access to vital commodities, such as lithium and rare earth minerals, which are essential for the green energy transition. The Council on Foreign Relations has extensively covered the strategic importance of Latin American lithium resources.
Expert Perspectives: A Balancing Act
“The ‘Greater North America’ concept is a bold attempt to redefine U.S. Strategic interests in the hemisphere,” says Dr. Renata Segura, a Latin American security expert at Georgetown University. “However, its success will depend on the U.S.’s ability to build genuine partnerships based on mutual respect and shared interests, rather than simply imposing its will on the region.”
“This strategy risks alienating key partners in Latin America if it’s perceived as a unilateral attempt to reassert U.S. Dominance. The key will be demonstrating a commitment to collaborative security solutions and addressing the underlying economic and social challenges that contribute to instability.” – Dr. Michael Shifter, Senior Fellow at the Inter-American Dialogue.
The Global Chessboard: Implications for China and Russia
The “Greater North America” strategy isn’t happening in a vacuum. It’s part of a larger geopolitical competition between the U.S., China, and Russia. China has been steadily increasing its economic and political influence in Latin America, investing heavily in infrastructure projects and forging closer ties with regional governments. Russia, while less economically involved, has sought to expand its military presence in the region, offering arms and training to countries like Venezuela and Nicaragua.
The U.S. Views both China and Russia as potential challengers to its dominance in the Western Hemisphere. The “Greater North America” strategy is, in part, an attempt to counter their influence and maintain a favorable balance of power. This could lead to increased tensions and a more polarized geopolitical landscape. The Carnegie Endowment for International Peace recently published a report detailing the implications of great power competition in Latin America.
the success of the “Greater North America” strategy will hinge on the U.S.’s ability to navigate a complex web of regional dynamics and geopolitical rivalries. It’s a high-stakes gamble that could reshape the future of the Americas – and, by extension, the global order. What do you think? Will this strategy foster greater cooperation or exacerbate existing tensions?
