近年来，“美国优先”（America First）政策成为美国外交与国内议程的核心口号。这一理念强调将美国国家利益置于全球合作之上，主张减少对外援助、重新谈判贸易协定、限制移民并质疑多边国际组织的作用。然而，媒体普遍指出，这种单边主义倾向正在削弱美国的全球领导力，并导致其在关键国际事务中日益孤立。多家主流媒体分析认为，“美国优先”虽短期内迎合了部分选民对全球化负面影响的不满，但长期来看却损害了美国与盟友之间的信任。例如，在气候变化、疫情防控、核不扩散等全球性挑战面前，缺乏协调与合作使美国难以发挥建设性作用。此外，退出《巴黎协定》、世界卫生组织及跨太平洋伙伴关系协定等举动，进一步凸显其“独行”姿态。更值得警惕的是，当美国放弃多边机制时，其他国家正加速填补其留下的权力真空。中国、欧盟等力量在全球治理中扮演更积极角色，而美国则可能错失塑造未来国际规则的机会。因此，媒体评论普遍认为，“美国优先”若走向极端，最终带来的不是强大，而是孤独——一个在全球舞台上形单影只的超级大国。
In recent years, the ‘America First’ policy has become a central slogan in U.S. foreign and domestic agendas. This doctrine prioritizes American national interests above global cooperation, advocating for reduced foreign aid, renegotiated trade deals, restricted immigration, and skepticism toward multilateral institutions. However, media outlets widely argue that this unilateral approach is eroding America’s global leadership and increasingly isolating it on critical international issues.Major news analyses suggest that while ‘America First’ resonates with certain voters frustrated by globalization’s downsides in the short term, it damages long-term trust with allies. On global challenges such as climate change, pandemic response, and nuclear non-proliferation, the lack of coordination limits America’s ability to play a constructive role. Withdrawals from the Paris Agreement, the World Health Organization, and the Trans-Pacific Partnership further underscore this go-it-alone stance.More concerning is that as the U.S. steps back from multilateral frameworks, other powers are swiftly filling the vacuum. China, the European Union, and others are taking more active roles in global governance, potentially sidelining the U.S. from shaping future international norms. Thus, media commentary largely concludes that if taken to extremes, ‘America First’ may not lead to strength—but to solitude: a superpower walking alone on the world stage.
