Retired four-star U.S. Army Gen. Jack Keane said Monday that the Iranian government “fundamentally miscalculated” President Trump as conflict in the Middle East persists.

“What these guys did, Rita and John, is they fundamentally miscalculated President Trump,” Keane told radio hosts John Catsimatidis and Rita Cosby on WABC’s “Cats & Cosby” program. “They bought into the fact that Trump really wanted to negotiate and they could stall those negotiations, and that even if he did go to war, it would only last a couple or three days because he wouldn’t have the patience to deal with it beyond that.

“What a fundamental miscalculation that they did here, and they’re certainly suffering a much-deserved consequence of all of that,” he added.

The speaker of the Iranian Parliament, Mohammad Bagher Ghalibaf, has warned the U.S. and Israel to avoid targeting infrastructure in the nation.

“Let the enemy know that whatever they do, we will undoubtedly respond with a proportionate and immediate retaliation; no malice will go unanswered, and today we decree the rule of ‘an eye for an eye’; bluntly, without exception.,” Ghalibaf wrote on social platform X.

On Monday, Trump called the war against Iran an “excursion” that would be over “very soon,” comments that came as he dealt with increasing oil prices, troop casualties and allies facing retaliation from Tehran.

“This was just an excursion into something that had to be done. We’re getting very close to finishing that too,” Trump said during a press conference.

Defense Secretary Pete Hegseth told reporters Tuesday that it will be an “intense day” in Iran but called the military operation “contained.” Both Hegseth and Trump have signaled that the U.S. is not ruling out deploying troops to the region in the future.

The comments came days after the president said he would only accept “unconditional surrender” from Iranian leadership.

About $5.6 billion in munitions were used by the Pentagon in the first two days of the U.S. military operation against Iran, The Hill was told Monday night by a congressional source.
