Pentagon reports Iran's nuclear facilities were "completely obliterated" in June strikes, offering a more optimistic assessment than earlier estimates while Iran acknowledges damage.

The ultimate success of the U.S. and Israeli strikes, and so Trump's decision to intervene militarily, depends on how Iran chooses to react. Some analysts fear this action will accelerate Iranian efforts to build a nuclear weapon, with hardliners in Tehran now viewing it as an urgent priority.

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’s president has ordered the country to suspend its cooperation with the International Atomic Energy Agency after American airstrikes hit its most-important nuclear facilities.

The decision means that international inspectors will not be able to oversee sites. Experts have warned that Tehran could revive plans to build a bomb.

Iranian President Masoud Pezeshkian has approved a law to halt cooperation with the International Atomic Energy Agency (IAEA), a move which will likely obscure any attempt by Tehran to restart its damaged nuclear program.
