Stephen Colbert on Tuesday took on Donald Trump over his “chilling” genocidal threat to Iran, one that the president backed down on after the U.S. agreed to a two-week ceasefire with the country.

The “Late Show” host — who recorded his monologue prior to Trump pressing pause on the threat — read the president’s “very upsetting” declaration that a “whole civilization will die tonight, never to be brought back again.”

“But I also want to point out that he doesn’t say which civilization will die tonight ’cause ours has been seen wandering on a highway overpass,” he quipped.

Colbert noted that Trump had apparently vowed to deliver the “civilization-ending blow” by a Tuesday deadline of “8:00 P.M. EASTERN TIME,” per a post shared to his Truth Social platform over the weekend.

“So, bad news, the world might end. Good news, not until after ‘Wheel of Fortune,’” he joked. “I’d like to buy a vowel and a bunker, please.”

The “Late Show” host pointed out that Trump concluded his threat with “God Bless the Great People of Iran!”

“Kind of a mixed message there, like when Godzilla wore a T-shirt that said, ‘I ❤️ Tokyo,’” he cracked.
