President Donald Trump said on Saturday that the United States could launch renewed military action against Iran if it “misbehaves,” underscoring ongoing tensions as Washington reviews a new Iranian proposal aimed at de-escalation.

“If they misbehave, if they do something bad — but right now, we’ll see. It’s a possibility that could happen, certainly,” Trump told reporters when asked whether he might authorize fresh strikes.

The remarks came as Iran submitted what officials described as a revised 14-point proposal on Thursday outlining a framework for a potential agreement with the United States.

However, a senior Iranian official told Reuters that the proposal, so far rejected by Trump, would open shipping in the Strait of Hormuz and end the U.S. blockade of Iran while leaving talks on Iran's nuclear program for later. Future talks would then be held on curbs to ​Iran's nuclear program in return for the lifting of sanctions, with Iran demanding Washington recognize its right to enrich uranium for peaceful purposes, even if it agrees to suspend its nuclear program.

"Under this framework, negotiations over the more complicated ​nuclear issue have been moved to the final stage to create a more conducive atmosphere," the official said.

According to two sources familiar with the plan cited by Axios, the proposal calls for a one-month negotiation period to reach a deal reopening the Strait of Hormuz, lifting what Iran describes as a U.S. naval blockade, and bringing a permanent end to hostilities involving Iran and Lebanon.

Only after such an agreement is secured would a second round of talks begin, lasting an additional month and focused on reaching a deal over Iran’s nuclear program, the sources said.

Trump was briefed on the proposal on Thursday by Brad Cooper, the head of U.S. Central Command, who also presented updated military strike plans targeting Iran. Cooper later traveled to the region, where he met with U.S. troops aboard the USS Tripoli in the Arabian Sea on Saturday.

While Trump said on Friday he was not satisfied with the Iranian proposal, he indicated a more measured approach a day later, telling reporters before departing Palm Beach for Miami that he intended to review the details during his flight.

“I’m looking at it. I’ll let you know about it later… They told me about the concept of the deal. They’re going to give me the exact wording now,” he said.

Shortly afterward, Trump struck a more critical tone in a post on Truth Social, saying he “can’t imagine that it would be acceptable” and arguing that Iran “has not yet paid a big enough price for what they have done to Humanity, and the World, over the last 47 years.”
