Israel and the U.S. struck Iranian nuclear facilities, resulting in what Trump has described as "total obliteration" of three sites: Fordow, Natanz, and Isfahan. Israel said Iran had nuclear ambitions that posed an existential threat to its existence.

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 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.
