The US military opted against using bunker-buster bombs on Iran's Isfahan nuclear site due to its depth, rendering the bombs ineffective, according to Gen. Dan Caine. Tomahawk missiles were used instead. While US officials believe Isfahan houses a significant portion of Iran's enriched uranium, post-strike assessments indicate the attacks may only have set back Iran's nuclear program by months, not years. Lawmakers received classified briefings acknowledging that not all Iranian nuclear materials were eliminated, but this wasn't the mission's objective. Satellite imagery suggests Iran may have moved materials after the strikes.
