President Trump turned down Vladimir Putin's Monday proposal to transfer 450kg of Iran's near-weapons-grade uranium to Russia, part of wider efforts to end the U.S.-Iran conflict, citing the need for direct U.S.-secured resolution.
The stockpile could yield over 10 nuclear bombs; past similar offers were rejected by Iran, and U.S. officials prioritize avoiding reliance on Russia amid allegations of its support for Tehran.
The move signals deepening U.S.-Russia friction, with Trump noting mutual aid to adversaries and Defense Secretary Hegseth hinting at alternative "options" like strikes, potentially escalating the war's nuclear risks.
