President Trump issued his most ominous warning yet toward Iran on Tuesday, declaring that “a whole civilization will die tonight” ahead of an 8 p.m. EDT deadline tied to escalating U.S. military action in the ongoing Iran Conflict.
In a Truth Social post, Trump coupled sweeping threats with a suggestion that last-minute change could still alter the course of events.
“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. “However, now that we have Complete and Total Regime Change, where different, smarter, and less radicalized minds prevail, maybe something revolutionarily wonderful can happen, WHO KNOWS?”
The president has repeatedly escalated his rhetoric in recent days, previously warning that the United States could target Iran’s infrastructure—including power plants and bridges—and declining to rule out sending ground troops. He has also set and extended multiple deadlines for Iran to reopen the Strait of Hormuz, a critical global shipping route that has remained effectively closed for weeks during the conflict.
Trump’s claim that Iran has undergone “Complete and Total Regime Change” remains unclear. While the country’s longtime supreme leader was killed at the outset of the Iran Conflict, Iran’s leadership has since consolidated power under his son, and senior officials have continued to project defiance.
That defiance has extended to public mobilization efforts. Iranian figures have encouraged civilians to form human chains around key infrastructure sites that Trump has threatened to strike.
Alireza Rahimi, identified by Iranian state television and the Associated Press as secretary of the Supreme Council of Youth and Adolescents, issued a video message calling on “all young people, athletes, artists, students, and university students, and their professors” to link arms around power plants on Tuesday.
Even as he warned of catastrophic destruction, Trump struck a contradictory tone, pairing threats with praise for the Iranian people.
“We will find out tonight, one of the most important moments in the long and complex history of the World. 47 years of extortion, corruption, and death, will finally end,” he wrote. “God Bless the Great People of Iran!”
The Pentagon appeared to begin acting ahead of the deadline, launching strikes Tuesday on military targets on Iran’s Kharg Island, a key energy hub.
Behind the scenes, diplomatic efforts have continued. The United States and Iran have received a ceasefire proposal brokered by Egypt, Pakistan, and Turkey that would include a 45-day pause in fighting and the reopening of the Strait of Hormuz. Trump said earlier this week that Iran had made a “significant” offer, but added it was “not good enough.”
Markets have reacted to the uncertainty, with oil prices climbing to $113.40 per barrel Tuesday morning, up $2.15 from the previous day.
While Trump has leaned into maximalist threats, other U.S. officials have signaled a more measured approach. Vice President JD Vance, speaking from Hungary where he is supporting Prime Minister Viktor Orbán’s reelection bid, emphasized that negotiations remain ongoing.
“We’re going to find out but there’s going to be a lot of negotiation between now and then,” Vance said.
The president’s latest remarks have also triggered backlash from some of his allies and conservative figures. Rep. Marjorie Taylor Greene (R-Ga.), once a close Trump ally, called for his removal from office under the 25th Amendment.
“25TH AMENDMENT!!!” Greene wrote on X. “Not a single bomb has dropped on America. We cannot kill an entire civilization. This is evil and madness.”
Conspiracy theorist Alex Jones echoed that criticism, calling Trump’s language a “war crime” and comparing his rhetoric to that of “an unhinged super villain.”
Trump’s Tuesday deadline marks the latest flashpoint in a rapidly intensifying Iran Conflict, where threats of large-scale escalation now sit alongside fragile diplomatic efforts—leaving the immediate path forward uncertain as the clock ticks toward the president’s self-imposed ultimatum.
