President Donald Trump announced Saturday evening that the U.S. had carried out military strikes on three Iranian nuclear sites earlier Saturday.

“We have completed our very successful attack on three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan,” Trump announced on Truth Social. “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.”

The three sites, particularly Fordow, are deeply entrenched underground, and analysts believe that Israel lacked the capacity to destroy the Fordow site on its own. Fox News host Sean Hannity said that Trump told him that the U.S. had dropped six bunker-busting bombs on Fordow and launched a total of 30 Tomahawk cruise missiles from U.S. submarines at Natanz and Esfahan. He said that all three facilities were destroyed completely.

The strikes come before the end of the two-week period that the Trump administration had provided for a decision on potential strikes. 

In brief remarks from the White House, Trump said that the strikes were a “spectacular military success” and that the sites had been “completely and totally obliterated.”

Trump threatened further military action if Iran does not agree to make peace, warning Tehran that there are many other targets the U.S. can still hit “in a matter of minutes.” 

“If they do not, future attacks will be far greater and a lot easier,” Trump said. “This cannot continue. There will be either peace or there will be tragedy for Iran, far greater than we have witnessed over the last eight days.”

He also highlighted Iran’s four-decade history of attacks against U.S. personnel.

“I want to thank and congratulate Prime Minister Bibi Netanyahu,” Trump continued. “We worked as a team like perhaps no team has ever worked before, and we’ve gone a long way to erasing this horrible threat to Israel.”

Dana Stroul, the research director at the Washington Institute for Near East Policy and a deputy assistant secretary of defense for the Middle East under the Biden administration, told Jewish Insider that the “failed talks in Europe on Friday likely convinced [Trump] that diplomacy, at least in the short term, was futile.”

“The threat of a conventional war with the United States is what Iran’s leaders presumably fear most,” Stroul said. “For the past week of Israel’s operations, the Iranians have only responded with ballistic missiles and drones aimed at Israel. The real risk now is that Iranian leadership expands the scope of their retaliation, including aiming missiles at the U.S. and its partners, militia attacks on US forces, and potentially the targeting of energy infrastructure throughout the Middle East.”

She said that the “most pressing strategic question is whether US strikes make negotiations with the Iranian regime more or less likely, and whether Iran’s leaders are now more convinced of their need for a nuclear weapon or are finally willing to make concessions.”

Andrea Stricker, the deputy director of the nonproliferation and biodefense program at the Foundation for Defense of Democracies, told JI that further operations of some kind will likely be necessary to eliminate stockpiles of highly enriched uranium in tunnels at Esfahan.

She said that could entail more strikes, or a U.S. or Israeli commando operation to recover the nuclear material.

So far, the strikes are being supported by most congressional Republicans, while most Democrats are opposed, with many saying that the action was unconstitutional given that Congress did not authorize it.

“The regime in Iran, which has committed itself to bringing ‘death to America’ and wiping Israel off the map, has rejected all diplomatic pathways to peace. The mullahs’ misguided pursuit of nuclear weapons must be stopped,” Senate Majority Leader John Thune (R-SD) said. “As we take action tonight to ensure a nuclear weapon remains out of reach for Iran, I stand with President Trump and pray for the American troops and personnel in harm’s way.”

House Speaker Mike Johnson (R-LA) said the strikes “should serve as a clear reminder to our adversaries and allies that President Trump means what he says.”

“The President gave Iran’s leader every opportunity to make a deal, but Iran refused to commit to a nuclear disarmament agreement,” Johnson continued. “The President’s decisive action prevents the world’s largest state sponsor of terrorism, which chants “Death to America,” from obtaining the most lethal weapon on the planet. This is America First policy in action.”

Sen. Jim Risch (R-ID), the chair of the Senate Foreign Relations Committee, said: ”This war is Israel’s war not our war, but Israel is one of our strongest allies and is disarming Iran for the good of the world,” adding that the strike would “put an end to [Iran’s] ambitions” of destroying Israel and killing all Jews and could only have been carried out by the United States.

“This is not the start of a forever war. There will not be American boots on the ground in Iran,” Risch added, pushing back on concerns that anti-interventionists on both sides of the aisle have raised about a potential strike. “This was a precise, limited strike, which was necessary and by all accounts was very successful. As President Trump has stated, now is the time for peace.”

Sen. Roger Wicker (R-MS), chairman of the Senate Armed Services Committee, also praised Trump’s decision and said, “We now have very serious choices ahead to provide security for our citizens and our allies and stability for the middle-east.”

Sen. John Fetterman (D-PA), one of the most pro-Israel congressional Democrats, said “this was the correct move” by Trump and said he’s “grateful for and salute the finest military in the world.”

Rep. Ritchie Torres (D-NY), another outspoken Israel supporter, said, “The world can achieve peace in the Middle East, or it can accept a rogue nuclear weapons program—but it cannot have both.”

“The decisive destruction of the Fordow Fuel Enrichment Plant prevents the dangerous spread of nuclear weapons in the world’s most combustible region,” Torres continued. “No one truly committed to nuclear nonproliferation should mourn the fall of Fordow.”

Meanwhile, Rep. Thomas Massie (R-KY), who was championing legislation in the House aiming to block U.S. military action against Iran, condemned the strike as unconstitutional in a X post which was re-shared by Rep. Rashida Tlaib (D-MI). Rep. Warren Davidson (R-OH), another isolationist House Republican, similarly questioned the strike’s constitutionality.

Sen. Tim Kaine (D-VA), who is leading the Senate version of Massie’s resolution, asserted that the American people are “overwhelmingly opposed” to the prospect of war with Iran and suggested that the strikes were not necessary to set back Iran’s nuclear program.

“What made Trump recklessly decide to rush and bomb today?” Kaine continued. “Horrible judgment. I will push for all Senators to vote on whether they are for this third idiotic Middle East war.”

House Minority Leader Hakeem Jeffries (D-NY) said Trump had “dramatically increased” the risk of war in the Middle East and endangered U.S. troops.

“President Trump misled the country about his intentions, failed to seek congressional authorization … and risks American entanglement in a potentially disastrous war in the Middle East,” Jeffries said, adding that the administration must explain its decision to the country and brief Congress.

“Donald Trump shoulders complete and total responsibility for any adverse consequences that flow from his unilateral military action,” Jeffries continued.

Several House Democrats called for Congress to immediately return to Washington to vote on Massie’s resolution.

Rep. Jim Himes (D-CT), the ranking member of the House Intelligence Committee, said the strikes were a “clear violation of the Constitution” and that it is “impossible to know at this stage whether this operation accomplished its objectives.”

“We also don’t know if this will lead to further escalation in the region and attacks against our forces, events that could easily pull us even deeper into a war in the Middle East,” Himes said.

Rep. Sean Casten (D-IL) called the strikes “an unambiguous impeachable offense.”
