President Donald Trump said Saturday, June 21, that the US military struck three sites in Iran, directly joining Israel's effort to decapitate the country's nuclear program in a risky gambit to weaken a longtime foe amid Tehran's threat of reprisals that could spark a wider regional conflict.
There was no immediate acknowledgment from the Iranian government of any strikes being carried out. The country's state-run IRNA news agency early Sunday reported an attack on the country's Fordo nuclear site that activated air defenses. The agency did not elaborate.
The decision to directly involve the US in the war comes after more than a week of strikes by Israel on Iran that aimed to systematically eradicate the country's air defenses and offensive missile capabilities, while damaging its nuclear enrichment facilities. But US and Israeli officials have said that American stealth bombers and the 30,000-pound (13,500-kilogram) bunker buster bomb they alone can carry offered the best chance of destroying heavily fortified sites connected to the Iranian nuclear program buried deep underground.
"We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan," Trump said in a post on social media. "All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home."
Trump added in a later post that he would address the nation at 10 pm Eastern time, writing "This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISRAEL, AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR. THANK YOU!"
Trump said B-2 stealth bombers were used but did not specify what types of bombs were dropped. The White House and Pentagon did not immediately elaborate on the operation. The strikes are a perilous decision, as Iran has pledged to retaliate if the US joined the Israeli assault, and for Trump personally. He won the White House on the promise of keeping America out of costly foreign conflicts and scoffed at the value of American interventionism.
Trump told reporters Friday that he was not interested in sending ground forces into Iran, saying it's "the last thing you want to do." He had previously indicated that he would make a final choice over the course of two weeks.
Iran's Supreme Leader Ayatollah Ali Khamenei warned the United States on Wednesday that strikes targeting the Islamic Republic will "result in irreparable damage for them." And Iranian Foreign Ministry spokesman Esmail Baghaei declared "any American intervention would be a recipe for an all-out war in the region."
Trump has vowed that he would not allow Iran to obtain a nuclear weapon, and he had initially hoped that the threat of force would bring the country's leaders to give up its nuclear program peacefully.
The Israeli military said Saturday it was preparing for the possibility of a lengthy war, while Iran's foreign minister warned before the US attack that American military involvement "would be very, very dangerous for everyone."
The prospect of a wider war loomed. Iranian-backed Houthi rebels in Yemen said they would resume attacks on US vessels in the Red Sea if the Trump administration joined Israel's military campaign. The Houthis paused such attacks in May under a deal with the US.
The US ambassador to Israel announced that the US had begun "assisted departure flights," the first from Israel since the Hamas-led attack on Oct. 7, 2023, that sparked the war in Gaza.
White House press secretary Karoline Leavitt said Thursday that Trump planned to make his decision on the strikes within two weeks. Instead, he struck just two days later. Trump appears to have made the calculation — at the prodding of Israeli officials and many Republican lawmakers — that Israel's operation had softened the ground and presented a perhaps unparalleled opportunity to set back Iran's nuclear program, perhaps permanently.
The Israelis say their offensive has already crippled Iran's air defenses, allowing them to already significantly degrade multiple Iranian nuclear sites. But to destroy the Fordo nuclear fuel enrichment plant, Israel appealed to Trump for the bunker-busting American bomb known as the GBU-57 Massive Ordnance Penetrator, which uses its weight and sheer kinetic force to reach deeply buried targets and then explode. The bomb is currently delivered only by the B-2 stealth bomber, which is only found in the American arsenal.
If deployed in the attack, it would be the first combat use of the weapon. The International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility.
