A senior U.S. official has indicated that the preliminary agreement reached with Iran is not yet final, and both sides retain the option to withdraw. The official outlined the 14 points of the memorandum of understanding scheduled to be signed in Switzerland. Crucially, upcoming negotiations will center on determining the specific order in which the agreed-upon steps will be implemented. The official, speaking anonymously, emphasized the importance of the upcoming meeting in Switzerland for converting the memorandum into a comprehensive, long-term agreement. While the preliminary accord represents progress, its success hinges on resolving outstanding issues related to the timing and execution of its provisions. The U.S. official stressed that no final deal is guaranteed at this stage.
