In the most explicit threats of mass civilian destruction by a sitting U.S. president in modern history, Donald Trump issued a series of escalating ultimatums to Iran between March 13 and April 7, 2026, threatening to annihilate Iran's entire civilian infrastructure if the country did not reopen the Strait of Hormuz and accept U.S. ceasefire terms.
\nOn March 13, Trump stated: \"I could take out things within the next hour, power plants that create the electricity, that create the water… We could do things that would be so bad they could literally never rebuild as a nation again.\"
\nOn April 5, Trump set a Tuesday, April 7 deadline, threatening to bomb Iran \"to the Stone Ages\" if a deal was not struck.
\nOn April 6, at a press conference, Trump stated: \"Every bridge in Iran will be decimated by 12 o'clock tomorrow night, every power plant in Iran will be out of business, burning, exploding and never to be used again. I mean complete demolition by 12 o'clock, and it will happen over a period of four hours if we wanted to.\"
\nLater that evening, Trump warned: \"A whole civilization will die tonight.\"
\nOn April 7, Trump declared the deadline \"final\" and said he would not extend it again, warning that the \"entire country\" could be taken out.
\nThese threats were made during the ongoing 2026 Iran war, which by April 7 had killed over 3,400 people across the Middle East, including more than 1,600 Iranian civilians according to Iranian officials. At least 220 children under 18 and 254 women were among the dead. Iran's Red Crescent reported 65 schools and 32 medical facilities damaged since the war began.
\nIran rejected a proposed 45-day ceasefire, demanding a permanent end to the war. Diplomatic efforts through intermediaries had failed to produce an agreement as the deadline approached.
\nThreatening to destroy \"every bridge\" and \"every power plant\" in an entire nation is the textbook definition of an indiscriminate attack under international humanitarian law. Additional Protocol I, Article 51(4) prohibits attacks that \"are not directed at a specific military objective\" and those that \"employ a method or means of combat which cannot be directed at a specific military objective.\"
\nA threat to destroy every bridge in a country of 88 million people does not distinguish between bridges carrying military traffic and bridges carrying civilians to hospitals, schools, and markets. It is inherently indiscriminate.
\nOver 100 international law professors signed a letter published by Just Security warning that U.S. strikes on Iran violate the UN Charter and may constitute war crimes. The letter represents one of the largest coordinated academic legal responses to U.S. military action in recent history.
\nEven if some infrastructure targets could theoretically qualify as military objectives, the explicit goal of ensuring Iran \"could literally never rebuild as a nation again\" demonstrates that the intended civilian harm vastly exceeds any conceivable military advantage. This fails the proportionality test under Rome Statute Article 8(2)(b)(iv).
\nUnder international law, the threat of an unlawful attack is itself actionable. The Rome Statute's provisions on war crimes apply to the ordering and planning of attacks, not only their execution. A head of state publicly declaring the intent to commit indiscriminate attacks creates command responsibility.
