牛弹琴：美国战略，有重大变化

Core Viewpoint - The latest U.S. National Security Strategy indicates a significant shift in American strategic focus, particularly towards the Western Hemisphere, while also reflecting a nuanced approach to China, which is no longer labeled as the "primary threat" [5][6][42]. Group 1: Strategic Focus - The U.S. will prioritize the revival of the Monroe Doctrine to reassert dominance in the Western Hemisphere, aiming to prevent non-Western competitors from deploying military forces or controlling strategically important assets in the region [5][40]. - The report emphasizes a realignment of military deployments to address urgent threats in the hemisphere while reducing presence in regions deemed less critical to U.S. national security [5][40]. - The U.S. identifies four primary tasks: national security and border control, revitalization of the Monroe Doctrine, economic security, and addressing China and the Indo-Pacific region [6][43]. Group 2: China Relations - China has been downgraded to a secondary target in U.S. strategic priorities, reflecting a shift in perception from being the "primary threat" to being viewed more as an economic competitor [6][42][45]. - The report acknowledges the evolution of U.S.-China relations from a disparity between a mature economy and a poor one to a "near-equal" relationship, marking a significant change in rhetoric [9][45]. - The U.S. recognizes the failure of its trade war against China, admitting that China has adapted to U.S. tariffs and strengthened its supply chain control [9][45]. Group 3: Military and Economic Strategy - The report states that maintaining military superiority to deter conflict over Taiwan is a priority, but it also suggests that this is an "ideal situation," indicating potential concerns about U.S. military capabilities [10][46]. - The U.S. plans to build a military capable of rejecting aggression in the first island chain, but it emphasizes that allies must contribute more to collective defense efforts [12][48]. - The report highlights that economic competition is now viewed as the ultimate battleground, with military deterrence becoming less central to U.S. strategy [14][50]. Group 4: European Relations - The strategy outlines a significant ideological divide between the U.S. and Europe, suggesting that Europe faces a decline in its traditional demographic and cultural identity [16][52]. - The report expresses concerns about the future of certain NATO members becoming majority non-European populations, hinting at a perceived threat to European civilization [16][52].
