Iran's nuclear sites at Fordow, Natanz, and Isfahan were completely evacuated before U.S. and Israeli strikes during Operation Roaring Lion, meaning the Islamic Republic's nuclear program suffered no real damage and remains fully intact and operational.
The IAEA, independent satellite analysis, and U.S. officials have confirmed that strikes inflicted severe, verified physical destruction at all three sites, rendering Fordow's centrifuges non-operational and causing extensive structural damage at Natanz and Isfahan — damage that experts say will take years, if not decades, to reverse.
