President Donald Trump announced Saturday evening that the United States had conducted successful airstrikes against three key Iranian nuclear facilities.In a Truth Social message posted just before the 8 p.m. hour on the East Coast, Trump said the attacks on the Fordow, Natanz, and Isfahan nuclear sites were complete and “all planes are safely on their way home.” The strikes mark the first direct U.S. military involvement in the escalating Israel-Iran conflict that began nine days ago.”A full payload of BOMBS was dropped on the primary site, Fordow,” Trump wrote. “There is not another military in the World that could have done this. NOW IS THE TIME FOR PEACE! Thank you for your attention to this matter.Trump followed up with a post announcing he would address the nation at 10 p.m. ET.The surprise bombing campaign — Trump had given Iran a deadline of two weeks to make a deal as recently as Thursday — effectively brings the U.S. into a new war in the Middle East, with the decision coming directly from a commander-in-chief who ran his successful campaign with an explicitly anti-war message.The early responses from the right illustrated the divide among Republicans, and Trump supporters more broadly, about getting involved in the conflict in Iran.”This is not constitutional,” said Kentucky Rep. Thomas Massie, a libertarian Republican often at odds with the new Trump administration.Senator John Fetterman, the Democrat from Pennsylvania who is among strongest supporters of Israel in the caucus, called it “the correct move.”Online, MAGA supporters and influencers were far less assured. Steve Bannon, among the more vocal opponents to U.S. military action in Iran, said on his War Room podcast: “You’re kicking over a hornet’s nest — this is as bad a place in the world as ever.””The U.S. has become a combatant in the Persian War,” Bannon said.The move to send American troops into Iranian airspace to drop what are presumed to be the “bunker-buster” bombs known as Massive Ordnance Penetrators (MOP) represents an extraordinary ramping up of tensions between Iran and the West, and nothing less than a reordering of American foreign policy.Under three presidents, including Donald Trump, the U.S. has been reluctant to get directly involved in regional conflicts, from Syria to Yemen. While Trump fired a few dozen Tomahawk cruise missiles at Syria in the first year of his first term — and famously ordered the strike that killed Qasem Soleimani in 2020 — Iran is another matter. The American public is broadly against going to war with the Iranians, with 60 percent against direct intervention, according to a YouGov poll last week.This is a breaking news story.
