Summary
In June 2025, the U.S. used its powerful bunker-busting bombs, called the Massive Ordnance Penetrator, on Iran's deeply buried Fordo nuclear site. However, a classified assessment reportedly showed that the bombs did not significantly damage the site and only set back Iran's nuclear program by a few months, contradicting previous claims of complete destruction.
