The 60-day timeline for a final deal under the June Memorandum of Understanding between the United States and Iran ended on August 17 without an agreement, formally expiring the framework that had kept the war in its lowest-intensity phase since spring.
On August 1, President Trump had said he decided to "cancel" a planned attack on Iran because the "perimeters of a deal has been agreed to." Days later, Iranian officials denied participating in talks toward any such deal, a contradiction that left diplomats scrambling to establish what, if anything, had actually been negotiated.
August: Sanctions as the Chosen Weapon
With the MoU dead, the administration pivoted to economic pressure, expanding sanctions on Iran's procurement networks and enforcement against third parties. The strategy rests on the theory that financial isolation can bring Tehran to terms without another round of strikes; a theory the markets treat with skepticism every time tankers are attacked.
The expiration leaves the region where it was in July: blockade reinstated, strikes intermittent, and diplomacy reduced to back channels through regional capitals.
