How the old and new U.S. defense strategies differ on traditional priorities

The Trump administration has unveiled a fundamentally reconfigured National Defense Strategy that marks a dramatic departure from the 2022 framework established under President Biden. This comprehensive analysis examines the strategic recalibration across key global regions.

In the Western Hemisphere, the 2026 doctrine adopts an assertive stance, vowing to ‘actively and fearlessly defend America’s interests’ while guaranteeing military and commercial access to critical territories including the Panama Canal, Gulf of America, and Greenland. The strategy explicitly commits to providing ‘credible military options against narco-terrorists’ while emphasizing conditional cooperation with neighbors from Canada through Central and South America.

Regarding European security, the document characterizes Russia as a ‘persistent but manageable threat’ while noting NATO’s overwhelming economic and demographic advantages. The strategy contends that European NATO members, having committed to raising defense spending to 5% of GDP under Trump’s leadership, are now positioned to assume ‘primary responsibility for Europe’s conventional defense’ with more limited U.S. support. This includes taking the lead in supporting Ukraine’s defense efforts.

The Indo-Pacific region receives heightened priority, with the strategy framing Chinese dominance as an existential economic threat that could ‘effectively veto Americans’ access to the world’s economic center of gravity.’ The document outlines a more focused objective than previous strategies: simply to prevent Chinese regional domination rather than pursuing regime change or existential struggle, aiming for a ‘decent peace’ acceptable to both nations.

On the Korean Peninsula, the strategy designates South Korea as capable of taking ‘primary responsibility for deterring North Korea’ given its powerful military, robust defense industry, and mandatory conscription, requiring only ‘critical but more limited U.S. support.’

In the Middle East, the Department of War will empower regional allies to counter Iran and its proxies, emphasizing strong support for Israel’s self-defense, deepened cooperation with Gulf partners, and enhanced integration between Israel and Gulf states through the Abraham Accords framework. The strategy maintains America’s right to take ‘focused, decisive action’ to defend U.S. interests when necessary.
