Since Israel launched a 12-day war on Iran in 2025, the IAEA has been blocked by Tehran from visiting enrichment sites where the Islamic Republic is believed to store enough highly enriched uranium to potentially build as many as 10 nuclear weapons, should it choose to rush for the bomb. Iran long has maintained that its program is peaceful, though it is the only country in the world to have uranium enriched up to 60% purity without a weapons program. The U.S. and Iran offered contradictory remarks Tuesday about whether those sites would be inspected.
