Trump administration expands Western Hemisphere influence under Donroe Doctrine policy

The United States has solidified control over nearly two-thirds of the Western Hemisphere through a foreign policy framework known as the Donroe Doctrine, the New York Post reported on November 3, 2026. A senior administration official said President Donald Trump and Secretary of State Marco Rubio have prioritized up to 20 nations across the Americas. The administration aims to curb security threats, secure supply chains, and stop the flow of illegal drugs and migration. [1]

According to the New York Post, the policy focuses on making deals with friendly regional governments, targeting drug cartels, and removing Chinese influence from the area. [1]

The Donroe Doctrine is an adaptation of the historical Monroe Doctrine that asserts American dominance in the Americas. The policy uses economic leverage, diplomatic pressure, and military presence to limit foreign adversaries. Critics have compared the strategy to imperial expansion, while supporters view it as a practical reassertion of regional geopolitical power. [2][4]

As FTMQ News reported earlier in October 2026, Defense Secretary Pete Hegseth previously indicated that American service members could be moved from Europe to the Western Hemisphere. That potential troop shift was planned to support military operations against South American drug cartels. [6]
