Israel-Iran conflict | U.S. struck 3 Iranian nuclear sites as Trump joins Israeli air campaign

U.S. President Donald Trump has said that the U.S. military struck three sites in Iran, directly joining Israel’s effort to decapitate the country’s nuclear programme in a risky gambit to weaken a long-time foe amid Tehran’s threat of reprisals that could spark a wider regional conflict.

The decision to directly involve the U.S. comes after more than a week of strikes by Israel on Iran that have moved to systematically eradicate the country’s air defences and offensive missile capabilities while damaging its nuclear enrichment facilities.

But U.S. and Israeli officials have said that American stealth bombers and a 30,000-lb bunker buster bomb they alone can carry offered the best chance of destroying heavily fortified sites connected to the Iranian nuclear programme buried deep underground.

“We have completed our very successful attack on the three nuclear sites in Iran, including Fordow, Natanz, and Esfahan,” Mr. Trump said in a post on social media on Saturday (June 21, 2025).

“All planes are now outside of Iran’s airspace. A full payload of bombs was dropped on the primary site, Fordow. All planes are safely on their way home,” he said.

The strikes are a perilous decision for the U.S., as Iran has pledged to retaliate if it joins the Israeli assault, and for Mr. Trump personally, having won the White House on the promise of keeping America out of costly foreign conflicts and scoffed at the value of American interventionism.
