Trump's Diplomatic Push Hits Limits at UN and Summit

President Donald Trump's week of high-profile diplomacy, including a UN address and summit with China's Xi Jinping, has exposed limits to his global influence amid a stalemated Iran war and domestic political pressures. Analysts say Trump faces pushback from world leaders on issues like the Middle East and Ukraine, with his foreign policy agenda appearing stalled. His meeting with Xi yielded only a two-month trade truce extension, with Trump showing a non-confrontational stance toward Beijing. The Iran conflict, launched in February, has disrupted energy supplies and spread regionally, while allies have spurned Trump's demands for assistance. European and Brazilian leaders criticized his approach, and efforts to broker a Ukraine-Russia ceasefire gained little traction.
