On June 17, 2026, U.S. President Donald Trump and Iranian President Masoud Pezeshkian remotely signed a landmark 14-point memorandum of understanding to end the military conflict that began in February. The preliminary agreement establishes an immediate and permanent termination of military operations on all fronts, including Lebanon, while initiating the immediate removal of the U.S. naval blockade on Iranian ports and granting waivers for crude oil exports. The signing opens a critical 60-day window for intensive diplomatic negotiations to finalize complex long-term issues, specifically regarding the down-blending of Iran’s enriched uranium stockpiles under United Nations supervision and the formal scheduling of broader international sanctions relief.
