U.S. President Donald Trump has announced that he will soon review Iran’s latest peace proposal, though he expressed skepticism about its acceptance. The announcement came on Saturday through a post on Trump’s social media platform, Truth Social, where he stated that Iran had sent a plan for consideration but that he doubted it would be acceptable. Trump made the remarks while staying in West Palm Beach, Florida.

In his post, Trump argued that Iran had not yet paid enough for the harm it had caused to humanity and the world over the past 47 years. Details of Iran’s new proposal have not been disclosed, leaving the content and scope of the plan unclear. The report, citing AFP, noted that Trump’s comments may further reduce hopes for easing the ongoing tensions between the two countries.

The lack of transparency around the proposal and Trump’s dismissive tone suggest that prospects for diplomatic progress remain uncertain.
