Trump’s New Signals: Is America Redefining Its Global Security Commitments?

This analysis by Tughral Yamin, Senior IPS Associate, examines the strategic implications of the United States reducing major military exercises with South Korea. The policy insight explores whether the move reflects a broader shift in US security commitments driven by rising defense costs, depleted military stocks, and Trump’s emphasis on burden-sharing and strategic selectivity. It assesses the potential effects on South Korea, Japan, Taiwan, China, and NATO allies, particularly the risk that reduced US engagement could weaken confidence in American security guarantees. Importantly, the analysis considers whether these developments signal a significant transformation in US grand strategy, in which Washington increasingly places a price on its global leadership.
