President Donald Trump's outreach to North Korean leader Kim Jong Un, including cuts to military exercises with South Korea and the cancellation of another drill scheduled for next month, is prompting Japan, Taiwan and India to reassess their reliance on Washington. The decisions followed Trump's frustration with allies' support for his war with Iran and demands that partners spend more on their own defence, while a person briefed on U.S.-South Korean discussions said he wants to restart talks with Pyongyang and secure an international diplomatic success. Japan fears pressure over negotiations on the cost of hosting U.S. forces and possible leverage through October's Keen Sword exercises, while the diversion of U.S. military assets to the Middle East has raised concerns about deterrence against China. Taiwan is watching Trump's planned summit with Chinese President Xi Jinping as Washington holds up approval of a $14 billion arms package for Taipei. India is also becoming more cautious about long-term defence deals after U.S. tariffs and Trump's claims that he mediated an India-Pakistan ceasefire. Analysts say the developments could deepen doubts about U.S. security commitments and reinforce perceptions of Trump's transactional approach to foreign affairs.
