UN and Xi Summit Expose Limits of Trump's Global Influence

President Donald Trump's efforts this week to reassert US global leadership through a UN speech and a White House summit with Chinese leader Xi Jinping have highlighted the limits of his administration's foreign policy power, according to analysts cited by Reuters. The ongoing war with Iran, now in its seventh month, has disrupted energy markets and expanded regionally. Trump warned at the UN that the US could "annihilate" Iran without a deal, while the Trump-Xi summit yielded only a two-month extension of the trade truce, with Taiwan and rare earths remaining contentious issues. European and Asian allies have increasingly rejected Washington's demands, including support for the Iran conflict. Trump's efforts on Ukraine and Greenland have also stalled, with analysts noting more states are now willing to contradict the US, though the White House denies its foreign policy is at an impasse.
