Iran's Nuclear Facilities: Uncertainty Surrounds US Strikes on Uranium Stockpile

Strategic Insights

— 1 min read

Vice President JD Vance sparked controversy by suggesting that Tehran had moved its near-bomb-grade uranium before the US strikes on Iran's nuclear facilities. Israeli sources claimed that Iran had relocated approximately 880 pounds of uranium enriched to 60% purity from a secure storage plant in Isfahan. The International Atomic Energy Agency's director general, Mariano Grossi, stated that inspectors had not visited the sites since the bombings. Meanwhile, the US administration maintains its confidence in the success of the raids, while Vance implies that the uranium stockpile remains under Iranian control.
