ERBIL, Kurdistan Region of Iraq – US President Donald Trump on Saturday said he does not believe Tehran’s latest peace proposal would be acceptable, while leaving the possibility of renewed military action against Iran open.

Trump on Friday said that he is "not satisfied" with the latest Iranian negotiating proposal, expressing his preference for a diplomatic settlement as opposed to military action "on a human basis."

Iran then sent another 14-point proposal on Saturday, according to the semi-official Iranian Fars News agency, which said that it was in response to a proposal by the US and that the exchange of messages had continued through Pakistani mediators.

“I will soon be reviewing the plan that Iran has just sent to us, but can't imagine that it would be acceptable in that they have not yet paid a big enough price for what they have done to Humanity, and the World, over the last 47 years,” Trump wrote on Truth Social.

“If we left [Iran] right now, it would take 20 years for them to rebuild, but we’re not leaving right now. We’re gonna do it so that nobody has to go back in two years or five years,” he told reporters while reviewing the proposal on Air Force One.

Negotiations between Washington and Tehran have remained at an apparent deadlock since a ceasefire took hold weeks ago, with no clear timeline for when face-to-face talks might resume.

In Florida, Trump also told reporters that renewed military action against Iran is “a possibility” if a deal is not reached and the Islamic republic “misbehaves.”

On Wednesday, Trump said that "we're not flying anymore" to hold negotiations, criticizing the "18-hour flight times" the first round of talks in Islamabad entailed.

Tensions between the two remain high despite a fragile ceasefire, with disputes shifting from direct military confrontation to economic and maritime pressure.

On April 13, Washington imposed a naval blockade on Iranian ports after talks in Islamabad failed to secure a lasting agreement. Since then, US forces, under US Central Command (CENTCOM), have turned back dozens of vessels, disrupting Iranian trade.

Tehran has condemned the move, with President Masoud Pezeshkian calling it an extension of military action, while Iran has responded with restrictions around the Strait of Hormuz, contributing to rising global energy prices.
