Trump’s new National Defense Strategy shifts focus to deterring China and presses allies to shoulder more

A newly reported U.S. National Defense Strategy for 2026 outlines an “America First” approach that elevates defending the U.S. homeland and deterring China as top priorities, while signaling a reduced emphasis on European defense responsibilities. The document’s themes underline burden-sharing and warn that long-standing allies should not rely on Washington as the default backstop for their security.

The strategy, as described in reporting, frames China as the pacing challenge in the Indo-Pacific and calls for strengthening military ties with partners while building deterrence through posture, technology and planning. It also emphasizes that Washington can pursue stability with Beijing, but only from a position that recognizes China’s expanding capabilities and regional ambitions.

Europe told to take the lead on Europe

For European allies, the document’s message is blunt: NATO members should increase their own defense spending and capacity because U.S. priorities are shifting. The approach does not eliminate cooperation, but it does recast expectations, indicating that European states should be prepared to do more of the heavy lifting in their neighborhood while the U.S. concentrates its resources on other theaters.

The strategy also describes Russia as a serious threat, especially given nuclear capabilities, while suggesting it is more “manageable” than the challenge posed by China. That framing is likely to be read closely in European capitals, where leaders have pushed for long-term U.S. commitment amid continued security anxieties.

Western Hemisphere and technology priorities

Beyond Europe and Asia, the plan highlights the Western Hemisphere and strategic access points as crucial to U.S. security and influence. It signals heightened concern about adversarial footholds and the protection of key routes and territories, reflecting a broader push to secure nearby regions as part of a homeland-defense posture.

The strategy also stresses modernization in areas such as cyber capabilities, artificial intelligence and nuclear forces. In practical terms, that typically means accelerating procurement and reorganizing priorities across the defense establishment—changes that can ripple through alliance planning, global basing decisions and the defense industry for years.
