Abstract
The US-Japan alliance has evolved beyond its traditional bilateral security framework to encompass regional and global strategic cooperation. Since the 2015 revision of defense guidelines, Japan has assumed a more proactive security role, deepening trilateral partnerships with South Korea and the Philippines while engaging in AUKUS-related defense initiatives. Under a second Trump administration, Japan faces increased pressure to expand its defense contributions, enhance counterstrike capabilities, and assume greater financial responsibility for the alliance. However, Trump's transactional approach and protectionist economic policies could strain economic ties, particularly in trade and technology cooperation. Meanwhile, Japan must navigate growing tensions with China, balancing deterrence with economic interdependence. The shifting US approach to alliances, NATO, and multilateral economic frameworks under Trump may compel Japan to diversify its partnerships with Europe and the Indo-Pacific.
