The ceasefire between Israel and Iran did not stop Iranian Supreme Leader Ayatollah Ali Khamenei from firing off a post on X, slamming President Donald Trump."The U.S. president stated, Iran must surrender. Needless to say, this statement is too big to come out of the U.S. president's mouth," Khamenei wrote.On June 17, a few days before the U.S. carried out the strikes on Irans nuclear facilities, Trump took to Truth Social to demand an "unconditional surrender" from Tehran. In a separate message on the same day, Trump said the U.S. had "complete and total control of the skies over Iran."Trump also took a swipe at Khamenei himself, saying that the U.S. knew where the Iranian leader was hiding."We know exactly where the so-called Supreme Leader is hiding," Trump wrote. "He is an easy target, but is safe there we are not going to take him out (kill!), at least not for now. But we dont want missiles shot at civilians, or American soldiers.

However, Trump called it a "very weak response" before revealing that Iran gave the U.S. "early notice" of its planned retaliation."Iran has officially responded to our obliteration of their nuclear facilities with a very weak response, which we expected, and have very effectively countered. There have been 14 missiles fired 13 were knocked down, and 1 was set free, because it was headed in a nonthreatening direction. I am pleased to report that NO Americans were harmed, and hardly any damage was done," Trump wrote. "I want to thank Iran for giving us early notice, which made it possible for no lives to be lost, and nobody to be injured."FRONTRUNNERS EMERGE AS IRANIAN OFFICIALS DISCUSS POSSIBLE SUCCESSORS TO KHAMENEI: REPORTSince Israel launched its operation against Iran, Khamenei has been in hiding and, according to Reuters, his family is being guarded by the Vali-ye Amr special forces unit of Irans Revolutionary Guard Corps.
