For Immediate Release: April 7, 2026
(Washington, D.C.) — President Donald Trump’s April 7 threat that he might escalate U.S. attacks on Iran so that “a whole civilization will die tonight, never to be brought back again,” should profoundly alarm every U.S. and global citizen.
Whether Trump is threatening a massive conventional bombing campaign or making a veiled threat to use nuclear weapons to try to coerce Iran into submission, leaders of nuclear-armed states cannot, must not, threaten the end of “a whole civilization.”
Such threats are unacceptable and following through would be a massive war crime and humanitarian disaster. In addition, an attack on Iran’s Busherer Nuclear Power Plant would risk a radiological disaster in the region.
The only type of weapons in the U.S. arsenal that could destroy “a whole civilization” in a day would be nuclear weapons. Any use by the United States of nuclear weapons against Iran would permanently damage the United States’ reputation, shred its alliances, and would constitute a war crime for which everyone in the chain of command could be prosecuted.
Even if Trump is not considering the use nuclear weapons, but “only” intends to launch a massive conventional bombing against civilian targets in Iran, the effect would be the opposite of Trump’s ostensible goal: preventing Iran’s leaders from acquiring nuclear weapons.
Rather, it would reinforce the belief that the only way a nation can deter attack from an aggressive nuclear-armed state is to possess one’s own nuclear weapons. A further escalation of this war would thus provide further incentive for Iran – and possibly other states – to develop nuclear weapons.
During the course of the nuclear age, past U.S. presidents have issued veiled nuclear threats against smaller, less powerful but very determined nations only to learn that such threats do not lead them to capitulate. U.S. nuclear threats during the Korean War and later against China and the Soviet Union, as well as Nixon’s “madman” strategy, which involved a nuclear threat against North Vietnam and a massive strategic bombing campaign, failed to bend adversaries to U.S. goals.
We call on rational voices inside Trump’s circle of formal advisors, informal confidants, members of Congress from both parties, and global leaders to remind Mr. Trump that responsible leaders do not threaten to commit war crimes, that a further escalation of his illegal war would undermine U.S. and global security and risk the lives of innocent people in Iran and the Middle East, and that the responsible path forward and out of this war is to immediately end the hostilities.
