President Donald Trump said Monday that the most significant phase of U.S. military operations against Iran has yet to occur, describing current strikes as only the beginning of a broader campaign.

In an interview with CNN, Trump said American forces are conducting powerful operations but indicated a larger offensive is imminent. “We’re knocking the crap out of them,” he said. “I think it’s going very well. It’s very powerful. We’ve got the greatest military in the world, and we’re using it.”

The president added that the United States has not yet begun its most forceful actions. “We haven’t even started hitting them hard. The big wave hasn’t even happened. The big one is coming soon,” he said.

Trump also acknowledged uncertainty surrounding Iran’s leadership structure following the reported killing of Supreme Leader Ali Khamenei during the opening phase of joint U.S.–Israeli strikes. “We don’t know who the leadership is. We don’t know who they’ll pick,” Trump said, suggesting the regime is in flux.

The comments come as U.S. military operations continue against Iranian military and infrastructure targets. While the administration has framed the campaign as a decisive effort to weaken Tehran’s capabilities, several senior U.S. officials have expressed skepticism that the current offensive will result in near-term regime change.

The situation remains fluid, with Washington escalating pressure on the Islamic Republic while monitoring political developments inside Iran. Trump’s remarks signal that further military action is likely in the coming days as the conflict unfolds.
