Donald Trump on Tuesday morning threatened to annihilate the entirety of Iranian civilization should the country’s government ignore his 8pm ET deadline to reopen the strait of Hormuz.
The president’s own words, posted publicly and tied to a specific deadline and set of demands, provide unusually direct evidence of intent to violate international law, and were being met with shock and dismay by Democrats and a growing number of prominent conservatives.
“A whole civilization will die tonight, never to be brought back again,” Trump posted on Truth Social about the country with more than 90 million people. “I don’t want that to happen, but it probably will.”
“This is an extremely sick person,” said the Senate minority leader, Chuck Schumer, accusing Republicans of abetting the president in plunging the US into a “wanton war of choice”.
In his post, Trump followed with a reference to “complete and total regime change” and signed off with “God Bless the Great People of Iran”, making a formulation that suggested the destruction of the state and the benediction of its people were, in his telling, compatible.
“47 years of extortion, corruption, and death, will finally end,” he wrote, referencing the Islamic regime’s takeover of the country in 1979. “We will find out tonight, one of the most important moments in the long and complex history of the World.”
Neither the US nor Iran is a member of the international criminal court, meaning no formal ICC jurisdiction applies. The more immediate legal framework is the Geneva conventions of 1949 onwards, which both countries have ratified. Article 33 of the fourth convention explicitly prohibits collective punishment of a civilian population. Article 54 of additional protocol I – whose core principles are binding as customary international law even on states, like the US and Iran, that never ratified it – prohibits attacks on infrastructure indispensable to civilian survival, with only a narrow exception for objects used exclusively to sustain enemy armed forces.
The US has itself acknowledged this customary obligation, though the adoption of this position came under the Biden administration in 2024. In one formal UN submission, Washington said it treated the fundamental protections of additional protocol I as legally binding even without ratification.
Trump’s latest threat against the totality of Iranian civilization “shocks the conscience”, House Democratic leaders said in a joint statement, calling for a “decisive congressional response”.
“The House must come back into session immediately and vote to end this reckless war of choice in the Middle East before Donald Trump plunges our country into World War III,” the representatives Hakeem Jeffries of New York, Katherine Clark of Massachusetts and Pete Aguilar of California said in their statement. Members are not scheduled to return to Washington until next week.
Questions about the president’s mental state have grown louder since Trump’s expletive-ridden Easter Sunday message, with Democrats and critics calling him “unhinged” and a “madman”.
Senator Patty Murray described Trump’s post as “the rantings of a bloodthirsty lunatic” while Senator Chris Coons said: “This is a threat to commit a war crime.”
Representative Joaquin Castro said the threat “suggests he’s either considering using a nuclear weapon or wants Iran to believe he would”. Several Democrats said it was time to invoke the 25th amendment against Trump, a call to remove him from office and replace him with the next in line to the presidency.
Representative Nancy Pelosi, the former House speaker, said Trump’s “instability is more clear and dangerous than ever”.
“If the Cabinet is not willing to invoke the 25th amendment and restore sanity, Republicans must reconvene Congress to end this war,” she said in a statement.
Jason Carter, the grandson of the late Jimmy Carter, whose presidency was defined by the 1970 Iranian revolution and the subsequent 444-day hostage crisis, condemned Trump’s comments as “unAmerican” and “unChristian”.
“If my grandfather were here he would challenge all Americans – Democrats Republicans and especially Christians who worship the Prince of Peace – to stand up and say enough is enough,” Carter, who serves as the chair of the Carter Center’s board of trustees, said in a video statement. “The Islamist government of Iran has been our enemy, including an enemy of my family, but the people of Iran have never been our enemy. This country must be better than Donald Trump’s unbridled and dangerous rhetoric.”
It is not only Democrats; Trump’s Middle East war has fractured the American right, driving a deep divide between traditional hawkish conservatives who have long clamored for military action against Iran and the president’s anti-interventionist “America First” loyalists.
Reacting to Trump’s Tuesday post, the former US representative Marjorie Taylor Greene, who recently split with the president, in part over what she said was his abandonment of America First policy principles, called for invoking the “25TH AMENDMENT!!!”
“Not a single bomb has dropped on America,” she wrote. “We cannot kill an entire civilization. This is evil and madness.”
Nathaniel Moran, a Republican representative of Texas, said in a social media post he supports the president’s military intervention in Iran but disagrees with his threat to destroy a “whole civilization”. “That is not who we are, and it is not consistent with the principles that have long guided America,” Moran said.
Trump’s Truth Social post came the morning after a chaotic White House press conference in which Trump voiced his threats to reporters. “The entire country could be taken out in one night,” he told reporters on Monday, “and that night might be tomorrow night.”
When a reporter noted that deliberate attacks on civilian infrastructure violate the Geneva conventions, Trump did not dispute the point. “I hope I don’t have to do it,” he said, then pivoted: “Forty-seven years they’ve been negotiating with these people. They’re great negotiators, and because they’re not going to have a nuclear weapon.” Asked whether the war was winding down or escalating, he said only: “I can’t tell you.” Asked about a ceasefire, he said: “I can’t talk about the ceasefire.”
He reiterated the 8pm ET Tuesday deadline for Iran to reopen the strait or face strikes on energy infrastructure and bridges. Iran’s Islamic Revolutionary Guard navy for their part said on Monday that the strait of Hormuz “will never return to its previous state” for the US and its allies.
Trump also claimed, without providing evidence, that US intelligence had intercepted communications from Iranian civilians near active bombing sites urging American forces to continue. “Please keep bombing,” he quoted the alleged intercepts as saying. He dismissed concerns that destroying power and water infrastructure would harm ordinary Iranians, insisting they would willingly endure such losses for the chance at regime change.
The military campaign is being followed by Trump’s $1.5tn Pentagon budget request, submitted last week alongside sweeping cuts to domestic programs.
The rhetorical escalation of recent days also sits alongside a pattern of contradictions. Trump said in recent weeks that the US had no strategic need for the strait of Hormuz; days later he made its reopening the central condition of his ultimatum to Tehran. He claimed total dominance of Iranian airspace even as a US fighter jet was shot down over the country.
And he declared the war won, but now threatens its most destructive phase yet.
