As his self-imposed Tuesday night deadline for Iran to make a deal or face massive U.S. attacks draws closer, President Donald Trump’s threatening rhetoric is becoming increasingly ominous, with a seemingly apocalyptic warning that a “whole civilization will die tonight” if Tehran doesn’t agree to his demands.
“A whole civilization will die tonight, never to be brought back again. I don’t want that to happen, but it probably will,” Trump wrote on his social media platform.
At the same time, continuing a series of mixed messages, Trump said “maybe something revolutionarily wonderful can happen” now that the U.S. is dealing with “different, smarter, and less radicalized” leaders in Iran.
“We will find out tonight, one of the most important moments in the long and complex history of the World,” the president wrote.
Trump’s issued an ultimatum to Iran to make a peace deal that includes reopening the critical Strait of Hormuz by 8 p.m. ET, or face bombardment of its critical infrastructure — including all its bridges, power plants and desalination facilities.

Trump first threatened to target Iran’s civilian infrastructure on March 21, saying the sites would be hit in 48 hours if no deal was made. He’s backed away and extended the deadline several times, citing what he described as successful talks.
But the past few days, he’s ratcheted up his threats. On Sunday, he told ABC News Senior Political Correspondent Rachel Scott that “we’re blowing up the entire country” if no agreement was reached.
On Monday, he told reporters in the White House briefing room that “the entire country could be taken out in one night” and the U.S. had plans that could wipe out Iran’s power plants and bridges, sending it back to the “stone ages,” within four hours.
In the background, negotiations were taking place between the U.S. and Iran via mediators like Pakistan. “I think it’s going fine but we’ll have to see,” Trump said on Monday.
Oscillating between threats of major attacks and talks of diplomacy, Trump was asked on Monday if the war was winding down or escalating.
“I don’t know. I can’t tell you,” he told reporters. “It depends what they do. This is a critical period.”
Despite mixed accounts on whether Iran is still participating in the talks, mediators are continuing to push both sides to reach a deal before President Trump’s deadline, according to several U.S. officials and other sources familiar with the matter.
Pakistani Prime Minister Shehbaz Sharif on Tuesday asked Trump for an extension on his deadline.
“Diplomatic efforts for peaceful settlement of the ongoing war in the Middle East are progressing steadily, strongly and powerfully with the potential to lead to substantive results in near future. To allow diplomacy to run its course, I earnestly request President Trump to extend the deadline for two weeks,” Sharif said in a statement.
White House press secretary Karoline Leavitt said in a statement that Trump has “been made aware of the proposal, and a response will come.”

Tehran has vowed a “regret-inducing” response should the U.S. wipe out its energy infrastructure. The Islamic Revolutionary Guard Corps on Tuesday told neighboring Gulf countries it will no longer show “restraint” in selecting regional targets for retaliation.
Iran’s deputy minister of sports and youth, Alireza Rahimi, invited people to form human chains around the country’s electricity power plants in a video message published on Monday, according to the government’s Telegram channel.
In the U.S., Trump’s increasingly grave threats have prompted some rare Republican pushback. Sen. Ron Johnson, a Republican from Wisconsin, said he hopes Trump’s latest comments are “bluster.”
“I do not want to see us start blowing up civilian infrastructure … We are not at war with the Iranian people. We are trying to liberate them,” Johnson said on the “John Solomon Reports” podcast.
Some experts have warned that possible attacks on civilian infrastructure could constitute a war crime and violate international law.
“I’m not worried about it,” Trump said on Monday. “You know what’s a war crime? Having a nuclear weapon. Allowing a sick country with demented leadership have a nuclear weapon, that’s a war crime.”
