US President Donald Trump reiterated on Monday that Iran cannot have a nuclear weapon amid a lack of progress in diplomatic efforts to resolve the Middle East conflict. "The number one Goal is, and always will be, that Iran cannot have, in any way, shape, or form, a Nuclear Weapon," Trump said in a post on Truth Social. His comment came as the 60-day negotiating period to find a peace deal between the US and Iran was expiring, with no word of an extension and both sides seemingly as far apart as they were two months ago. Iran said Monday it is working to finalize a joint statement with Oman on a plan to manage the transit of ships through the Strait of Hormuz. Fully reopening the waterway to commercial shipping has been a key demand of the United States, but it remains unclear whether the deal will meet Washington's criteria.
