(AP) – Trump posted on Truth Social on Tuesday that a “whole civilization will die tonight, never to be brought back again.”

He told Fox News’ Maria Bartiromo on Sunday that his threat brought Iran to the negotiating table. He also said the Islamic Republic has made worse statements, such as “Death to America. Death to Israel. America is a Satan.”

Trump issued new warnings to strike Iran’s civilian infrastructure if its leaders don’t agree to give up its nuclear program.

“In one half of a day they wouldn’t have one bridge standing, they wouldn’t have one electric generating plant standing and they’re back in the stone ages,” Trump said.
