The Trump administration's National Security Strategy (NSS) released on December 4, 2025, presents a controversial shift in U.S. foreign policy, prioritizing the Western Hemisphere and a threat-oriented approach. This strategy, authored by President Donald Trump, diverges significantly from his 2017 NSS, which emphasized great-power competition with China and Russia. The 2025 NSS focuses on non-interventionism, 'America First' policies, and a reorientation of U.S. military presence, sparking debates among experts. The document's emphasis on the Western Hemisphere, with a focus on migration, organized crime, and 'hostile foreign incursion,' raises concerns about the administration's approach to Latin America. The strategy's threat-oriented vision and dubious tactics, including the use of lethal force and military assets, have sparked controversy. The NSS's treatment of China, Taiwan, and Europe also deviates from previous strategies, with a shift away from great-power competition and a focus on economic relationships. The strategy's impact on U.S. alliances and its potential to accelerate Europe's efforts to hedge against the U.S. are significant. The Middle East strategy, which downplays the region's importance, contrasts with Trump's earlier approach, highlighting the complexity of his foreign policy.
