U.S. President Donald Trump said on Truth Social that a potential agreement with Iran could be signed on Sunday, promising that the Strait of Hormuz would reopen immediately afterward. He added that the U.S. would later collect and neutralize underground nuclear debris in Iran or the United States. Trump expressed hope for a smooth process but warned of a “final option” if talks failed. Iran has not officially responded, and some of Trump’s remarks appear to contradict earlier Iranian statements about the timing of the memorandum of understanding.

Al Jazeera reported that Tehran acknowledged progress in the talks and that the draft text was under review by Iran’s National Security Council and the office of Supreme Leader Ayatollah Khamenei. An Iranian foreign ministry spokesperson said the deal would not be signed Sunday but likely within days. Analysts noted growing optimism compared to previous rounds, though regional conflicts, including in Lebanon, could still disrupt diplomacy.

British Prime Minister Keir Starmer voiced support for a sustainable peace deal in a phone call with Trump, while experts cautioned that despite optimism, uncertainty and political maneuvering could still affect the outcome.
