President Trump said he was “an hour away” from striking Iran on Monday when he called off the military strike at the request of Middle East leaders — and warned another “big hit” could still be coming.

“I was an hour away from making the decision to go today,” he told reporters at the White House.

“We’re all set to go,” he said. “It would have been happening right now. Yeah, it was all done, the boats, the ships were all loaded, they’re loaded to the brim, and we were all set to start.”

Trump announced Monday that he would not restart Operation Epic Fury to give the peace talks another chance after huddling with his national security team and speaking with Gulf leaders.

“I’m saying two or three days, maybe Friday, Saturday, Sunday, something, maybe early next week, a limited period of time, because we can’t let them have a nuclear weapon,” he said.
