US National Security Strategy: Reviving Monroe Doctrine, Limiting NATO

The Trump administration’s new National Security Strategy emphasizes a Western Hemisphere-focused ‘Monroe Doctrine’ approach while signaling potential constraints on NATO expansion and raising concerns about Europe’s cultural trajectory. The 33-page strategy document prioritizes border security and migration control, calls for strengthened partnerships across the Americas, and seeks diplomatic engagement with Moscow. The strategy sets the stage for significant policy debates as the administration prepares to unveil its National Defense Strategy, with implications for defense contractors and military planning across multiple regions.
