President Donald Trump warned that “a whole civilization will die” in Iran on Tuesday (April 7, 2026) if the country does not heed his ultimatum to accept U.S. war demands.

“A whole civilization will die tonight, never to be brought back again. I don’t want that to happen, but it probably will,” Mr. Trump wrote on his Truth Social platform. “WHO KNOWS?”

Mr. Trump did not give details but has already said the U.S. military could bomb Iran’s bridges, power plants and other civilian infrastructure into the “stone age.”
