The Pentagon's new National Defense Strategy marks a significant shift from previous administrations' focus on China as the top security threat. Instead, it prioritizes the US homeland and Western Hemisphere, highlighting concerns over access to key terrains like the Panama Canal and Greenland. The strategy criticizes past policies for neglecting American interests and calls for allies to take more responsibility for their own security, especially in Europe and Asia. It emphasizes a realist approach, moving away from grandiose strategies, and underscores the importance of deterring Russia, North Korea, and Iran, while maintaining a limited role in North Korea's deterrence. Relations with China are to be managed through strength rather than confrontation, avoiding mention of Taiwan, despite ongoing tensions. The strategy also advocates for greater burden-sharing with allies, particularly in Europe, and signals a shift towards non-interventionism and prioritizing US interests, especially in the Western Hemisphere.
