US Vice President JD Vance announced that President Trump has not yet decided whether to endorse a tentative memorandum of understanding (MOU) with Iran, as negotiations continue over unresolved issues in the draft agreement. Speaking at Joint Base Andrews, Vance noted that the timing and outcome of any endorsement remain uncertain, with specific disagreements centering on Iran's nuclear program. Key issues include the management of Tehran's highly enriched uranium stockpile and its future rights to uranium enrichment. While Vance expressed cautious optimism regarding Iran's engagement in the negotiations, he emphasized that more progress is needed before a formal agreement can be reached. Additionally, he acknowledged that the ceasefire between the US and Iran has faced incidents of violence, but he described these as typical of fragile truces. Washington continues to view the ceasefire as intact while reserving the right to conduct defensive actions if necessary. Vance's remarks provide the most detailed public update on the MOU process, indicating that a final agreement is still not imminent despite earlier reports of progress.
