We should be clear that Hegseth is not an officer in the US military, and this is clearly an illegal order. The fact that he has fired the JAGs who would tell him that is unsurprising, but does not change the facts. Any such killings would expose the individuals to a USMCJ Article 118 charge.
"In 2024’s The War on Warriors, Hegseth argues at length that US forces should ignore the Geneva conventions and other elements of international law governing the conduct of war."
“'What if we treated the enemy the way they treated us?” he asks. “Would that not be an incentive for the other side to reconsider their barbarism? Hey, Al Qaeda: if you surrender, we might spare your life. If you do not, we will rip your arms off and feed them to hogs.'”
He wrote a book in which he openly advocates for war crimes. Maybe, just maybe, it pays to believe him.
He probably said "no quarter" because it sounds cool and doesn't really know what it means. The most ironic part is how he is an avowed Christian warrior and says "no mercy" when mercy figures pretty prominently in Christianity.
It’s the one constant about this administration: you’re always wondering ”is this incompetence by not knowing what they’re saying or incompetence where they know what they’re saying”
