Several experts have cautioned that Iran likely moved a stockpile of near weapons-grade highly enriched uranium out of the deeply buried Fordow site before the strikes and could be hiding it.

Some experts said they believe the U.S. strikes have the potential to lead to a "fork-in-the-road" moment that could result in Tehran taking an even more dangerous path.

Iran just ended its cooperation with international inspectors, suggesting no post-bombing deal is imminent. That may point to a long game of hide-and-seek, punctuated by military action.
