“The so-called ‘Supreme Leader’ of Iran, who has not been so Supreme lately, had some nasty things to say about the United States and Europe,” Trump, who is in Palm Beach, Fla., for a fundraiser, tweeted Friday evening. “Their economy is crashing, and their people are suffering. He should be very careful with his words!”

Trump went on to urge Iran’s leaders to “abandon terror” and “Make Iran Great Again.”

“The noble people of Iran—who love America—deserve a government that’s more interested in helping them achieve their dreams than killing them for demanding respect,” Trump tweeted. “Instead of leading Iran toward ruin, its leaders should abandon terror and Make Iran Great Again!”
