Trump Administration Unveils New U.S. National Security Strategy with Hemisphere Focus

U.S. Releases Overhauled National Security Strategy Marking Major Geopolitical Shift

The United States has released a sweeping National Security Strategy that outlines a decisive reorientation of its global posture under President Donald Trump. The document highlights a renewed emphasis on American dominance in the Western Hemisphere, a fortified military presence in the Indo-Pacific, and a reassessment of long-standing assumptions about European stability and alliance structures.

Reasserting Control in the Western Hemisphere

A central pillar of the strategy is a modern revival of the Monroe Doctrine. Washington plans to expand and sustain military deployments across the Caribbean and Latin America to counter emerging regional threats. The emphasis signals a return to hemispheric primacy, with the U.S. framing the region as a critical buffer against external influence.

Sharper Tone Toward Europe

The strategy adopts an unusually sceptical view of Europe’s long-term trajectory. It warns of “civilisational erasure” driven by demographic and political shifts, questioning whether future European governments will remain aligned with foundational NATO values. While reaffirming alliance commitments, the U.S. urges European nations to assume greater defence responsibilities, suggesting openness to recalibrating expectations.

Deterrence in the Russia–China Theatre

Washington’s approach to Russia seeks managed stability and a negotiated path in Ukraine while maintaining robust deterrence. On China, the strategy underscores preventing conflict through military superiority, with Taiwan and the South China Sea flagged as priority flashpoints. Strengthening Indo-Pacific alliances remains a core operational objective.
