Secretary of Defense Pete Hegseth offhandedly made a remark about the Trump administration's attack on Iran during his speech on Friday that experts warned, if he's serious, could be a war crime — even just for him to say out loud.
"No quarter, no mercy for our enemies," said Hegseth. "Yet some in the press just can't stop. More fake news from CNN reports that the Trump administration underestimated the Iran war's impact on the Strait of Hormuz. The sooner David Ellison takes over that network, the better."
The phrase "no quarter" is often used colloquially in a political setting, but in a military context, it means any enemy combatants will be killed with no allowance for surrender — something that, as experts on X and Bluesky were swift to point out, is a violation of both international law and the U.S. military code.
"Went largely unnoticed but Hegseth on Iran said the U.S. would provide 'no quarter, no mercy for our enemies' during his press conference today," wrote Wall Street Journal national security reporter Alex Ward. "'No quarter' is a violation of international humanitarian law." He provided a link to the relevant provisions of the Geneva Convention.
"Today, Hegseth said: 'No quarter, no mercy for our enemies.' But the Defense Department's own Law of War Manual (pp. 209-210) says: 'It is forbidden to declare that no quarter will be given,'" wrote Claremont McKenna College professor Jack Pitney.
"Former USG war crimes lawyer here," wrote International Crisis Group senior adviser Brian Finucane. "Apropos of SecDef's remarks this morning: Denial of quarter — even the declaration of no quarter — is a war crime. And recognized as such by the US Government. From DoD's Manual for Military Commissions." He screenshotted the section of the manual, which stated denial of quarter is punishable by up to life in prison.
"Declaring that no quarter will be given is straightforwardly prohibited under international humanitarian law," wrote Stanford law professor Tom Dannenbaum. "When done to threaten an adversary, the declaration itself amounts to a war crime."
"Yet another thing to put in our back pocket," wrote Ryan Cooper of The American Prospect. "'Ship em to the Hague' is a completely valid option for a long and growing list of people who need to be dealt with."
