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

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.

The Pentagon on Wednesday sharpened its assessment of Iran's nuclear program, declaring that Iran's ability to build a nuclear weapon following the U.S. strike on its nuclear facilities is "closer to two years" away.

The move "was made to put America’s interests first," a White House spokeswoman said, as U.S. munitions have been depleted in recent years.

The decision was driven by the Pentagon’s policy chief, Elbridge Colby, and was made after a review of Pentagon munitions stockpiles.

Pentagon chief spokesperson Sean Parnell said the cutoff of some weapons deliveries to Ukraine was part of a global 'capability review.'
