Tensions between the United States and Iran intensified at the United Nations following Tehran's appointment as a vice president for the Nuclear Non-Proliferation Treaty (NPT) review conference. U.S. Assistant Secretary Christopher Yeaw labeled the move an "affront," citing Iran’s history of non-compliance with the IAEA. Despite the diplomatic friction, President Trump acknowledged that Iran’s most recent peace proposal was an improvement over previous offers but emphasized that it remains "not enough" to meet U.S. requirements, specifically the total removal of highly enriched uranium and guaranteed freedom of navigation in the Strait of Hormuz. In Tehran, internal fractures have emerged as Foreign Minister Abbas Araghchi reportedly admitted to regional mediators that there is no consensus among Iranian leaders on how to address Washington's demands. Simultaneously, Iran has sought to bolster its standing through international and military channels; President Vladimir Putin pledged Russian support for Iranian interests during a meeting in St. Petersburg, while the IRGC claimed to have seized 15 unexploded U.S. missiles for reverse-engineering. At the UN Security Council, Iranian Ambassador Amir Saeid Iravani accused the U.S. and Israel of conducting a "war of aggression" and an illegal maritime blockade since late February. While active hostilities in the Strait of Hormuz are currently paused, the waterway remains a central flashpoint as the U.S. continues to seize Iranian commercial vessels, actions Tehran has characterized as state-sponsored piracy.
