US and Iran Sign Islamabad Memorandum of Understanding: 60-Day Window Opens on Nuclear and Hormuz Talks

June 17, 2026 — President Trump and Iranian President Masoud Pezeshkian signed a 14-point Memorandum of Understanding in Islamabad, mediated by Pakistan and Qatar, opening a 60-day (extendable) negotiating window covering Iran's nuclear and missile programs, Strait of Hormuz navigation, and sanctions relief. Iran reaffirmed a no-nuclear-weapons commitment and agreed in principle to down-blend enriched uranium stockpiles under IAEA supervision, while sanctions-relief and frozen-asset provisions were left for follow-on negotiation. The MOU followed the collapsed Round 1 (April 11-12) and Round 2 (April 26) Islamabad talks and months of shuttle diplomacy by Pakistani Army Chief Gen. Asim Munir. Trump later said the 60-day window, nominally expiring in mid-August, was 'not a hard deadline.'
