Retired Military Officers Warn Trump's Iran Threats Are "Likely War Crimes"

"A Whole Civilization Will Die Tonight"

Donald Trump crossed a legal and moral line Tuesday morning when he threatened to annihilate Iranian civilization in a Truth Social post. Retired military officers immediately flagged the statement as a likely war crime under international law.

"I have to hope that this is bluster, and a negotiating tactic on his part," said retired Admiral Michael Smith, who commanded a carrier strike group in the US Navy. "He must understand that those types of threats themselves are likely war crimes."

The threat came after a weekend tirade in which Trump called Iranian leaders "crazy bastards" and demanded they stop blocking oil shipments through the Strait of Hormuz. By Monday, he was threatening to bomb Iranian infrastructure if his demands were not met by Tuesday.

No Concern About War Crimes

When reporters asked Trump at the White House whether he was concerned about committing war crimes, his answer was unequivocal: "not at all." He again threatened to destroy Iran's bridges and power plants, and refused to say whether civilian targets were off limits.

"While his comments previously on the bridges and electric power plants might have had military utility that would make it a justifiable target, his current claims have no legal standing," Smith said. "And yet, we have to have faith that the current military leaders will do what is legal."

That faith may be misplaced. Defense Secretary Pete Hegseth fired three generals last week in what appears to be retaliation for internal pushback against Trump's war plans. None of the fired officers have spoken publicly since their forced retirements.

The Nuclear Implication

The threat to kill a "civilization" in a single day implies the use of nuclear weapons, according to retired Army General Shawn Harris, who is running for Congress in Georgia.

"I think what he's basically saying is he's going to follow through on his plans of things he talked about two or three days ago of blowing up bridges, blowing up power facilities and all those type things," Harris said. "Hopefully we will get to a diplomatic agreement, but you know the Iranians, they're no pushover."

Naveed Shah, political director for the veterans group Common Defense, called Trump's rhetoric "unhinged."

"As an army veteran who served in Iraq, this type of rhetoric puts our troops in the region in greater danger," Shah said. "If we don't de-escalate, we will be dragged into another forever war in the Middle East that we can't afford."

Congress Surrenders War Powers

The threats come as Congress has effectively abdicated its constitutional responsibility to declare war. By narrow margins, the House and Senate rejected measures in early March requiring congressional approval for military operations against Iran.

Gary Corn, a retired Army staff attorney who teaches national security law at American University, said Congress has incrementally surrendered its war-making authority over decades.

"When you have the efforts in Congress failing, one can interpret it as an implicit acquiescence if not endorsement to what's gone on in the last 30 days," Corn said. He noted that Richard Nixon effectively ignored the repeal of the Gulf of Tonkin resolution and continued waging war in Vietnam 55 years ago.

Violating the Laws of War

Senator Elissa Slotkin, a Michigan Democrat and former defense official, laid out the legal stakes in clear terms.

"Targeting civilians en masse would be a clear violation of the law of armed conflict as laid out in the Geneva Conventions, as well as the Pentagon's Law of War Manual," Slotkin said. "This kind of focus on civilians is exactly what we accuse our adversaries of doing and what our military trains to avoid."

Slotkin -- whom Trump unsuccessfully targeted for prosecution last year after she circulated a video calling on service members to refuse illegal orders -- warned that military personnel could face legal jeopardy if ordered to carry out attacks on civilians.

"If they are today or have been asked to do things that violate the law and their training, it puts them in very real legal jeopardy," she said.

The firing of generals who may have resisted illegal orders, combined with Trump's explicit dismissal of war crimes concerns, suggests the guardrails are coming off. The question now is whether the remaining military leadership will uphold their oaths to the Constitution -- or follow orders that violate international law.
