The March 2026 Counter-Cartel Summit at US Southern Command, held concurrently with US military operations in Iran, demonstrated the Administration’s sustained prioritization of the Western Hemisphere, as codified in the December 2025 National Security Strategy and the January 2026 National Defense Strategy. A coalition of right-leaning Latin American governments—including those of Argentina, Ecuador, Chile, Paraguay, and the Dominican Republic—committed alongside the United States to employ military force against transnational criminal organizations.

Transnational criminal networks across the region have acquired advanced capabilities (e.g., drones, encrypted communications, AI-enabled cybercrime tools, and cryptocurrency infrastructure) that compound the security challenge for partner nations. The closure of the Strait of Hormuz elevated global petroleum prices and placed significant economic and political stress on Central American and Caribbean states dependent on oil imports, while also expanding China’s economic footprint in the region through high-volume commodity purchases and energy investments.

US military conflict in Iran created bandwidth constraints, reducing the senior leadership’s attention available to counter the PRC’s subtler instruments of influence across Latin America. The strategic environment demands that US and partner nation policymakers navigate simultaneous pressure from transnational criminal organizations, authoritarian regimes, and great power competition with both strategic clarity and disciplined prioritization of resources.
