Trump has delayed several deadlines for Iran, but Tuesday's nears with his most menacing threat

WASHINGTON (AP) — President Donald Trump has repeatedly pushed back deadlines for Iran to cut a deal or open the Strait of Hormuz, but his latest deadline for Tuesday came with his most perilous threat yet: “a whole civilization will die tonight, never to be brought back again.”

Trump's previous deadline was weeks ago, but it was postponed several times as the Republican president oscillated between heated threats, announced delays and proclamations that the negotiations were going well, sometimes in the same statement.

That was true in Trump's Truth Social post before his Tuesday 8 p.m. ET deadline. After threatening a “whole civilization," Trump said Iran's new leaders were more reasonable and “maybe something revolutionarily wonderful can happen, WHO KNOWS?”

Officials involved in diplomatic efforts said talks continued, but it was unclear if a deal would be reached by the deadline, which Trump has suggested was final. Trump raised the ante on his threats from Monday.

“They’ll have no bridges," he wrote. “They’ll have no power plants. They’ll have no anything.”

U.N. Secretary-General António Guterres warned the U.S. that attacks on civilian infrastructure are banned under international law, according to his office. Trump, speaking with reporters, said he's “not at all” concerned about committing war crimes with such attacks.

So how did Trump's deadline delays and threats escalate over the last weeks?

An ultimatum about reopening the Strait of Hormuz

On March 21, Trump posted on Truth Social that the U.S. would “hit and obliterate” Iranian power plants if it did not fully reopen the strait within 48 hours.

Iran had until the evening of March 23.

Then 12 hours before the deadline, Trump took to Truth Social to share what seemed good news: that both countries had productive conversations toward concluding the conflict.

He wrote that he had instructed the Pentagon to postpone any strikes on Iranian power plants and energy infrastructure for five days, to give more time for talks.

That pushed the deadline out to the end of that week.

A threat to target desalinization plants

Before that deadline, on March 26, Trump doubled down on his threats on Truth Social: “They better get serious soon, before it is too late, because once that happens, there is NO TURNING BACK, and it won’t be pretty!”

But later that day, he extended the deadline for 10 more days, to April 6 at 8 p.m. Eastern, and said on Truth Social that negotiations were “going very well.”

On March 30, Trump put out a mixed statement: celebrating progress in the talks with Iran while also expanding his threatened bombing if a deal wasn't “shortly reached,” adding that “it probably will be."

“We will conclude our lovely ‘stay’ in Iran by blowing up and completely obliterating all of their Electric Generating Plants, Oil Wells and Kharg Island (and possibly all desalinization plants!),” he wrote.

It's unclear how soon “shortly reached” meant for Trump, but a deal was not made as the deadline loomed.

An expletive-filled threat to attack power plants and bridges

“Remember when I gave Iran ten days to MAKE A DEAL or OPEN UP THE HORMUZ STRAIT," Trump said in a Truth Social post on Saturday, "Time is running out - 48 hours before all Hell will reign down on them.” He meant rain down.

As the deadline approached, his posts had doubled down on his threats until Sunday, when Trump pushed it again in an expletive-filled post.

“Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!! Open the F——-in’ Strait, you crazy bastards, or you’ll be living in Hell,” Trump said on Truth Social, followed by another post that specified 8 p.m. as the deadline.

Trump then suggested on Monday that Tuesday's deadline would be final, saying he'd already given Iran enough extensions.

“The entire country can be taken out in one night, and that night might be tomorrow night,” Trump said. “We have a plan, because of the power of our military, where every bridge in Iran will be decimated by 12 o’clock tomorrow night.”
