The United States has entered a critical diplomatic phase with Iran, delivering a one-day ultimatum for Tehran to publicly confirm the reopening of the Strait of Hormuz. The demand, communicated through both direct channels and regional mediators, requires Iran to guarantee the safety of commercial vessels by Saturday. Failure to comply will result in what U.S. officials describe as 'no good outcome' for the Islamic Republic. President Trump, currently meeting with NATO allies, remarked that the U.S. is 'very close' to concluding military operations, but emphasized that the cessation of strikes depends entirely on the maritime guarantee. The situation on the ground remains volatile. A total standstill in the Strait of Hormuz has entered its second week, with zero crude oil tankers transiting the area. Tensions have been further exacerbated by the rise of Iran’s new Supreme Leader, who has framed the current conflict around a personal vendetta to avenge his father’s assassination. In response to recent U.S. strikes following attacks on merchant ships off Oman, Tehran has warned it may formally disavow the existing Memorandum of Understanding (MoU), claiming the U.S. has already violated the ceasefire framework. Despite the escalating rhetoric, reports suggest that technical nuclear talks in Oman may still be proceeding as a secondary diplomatic track.
