US-Iran 60-Day Truce Deal Collapses as August 17 Deadline Expires Without Agreement

The 60-day negotiating window established by the June 17 U.S.-Iran Memorandum of Understanding expired on Monday, August 17, 2026, without producing a permanent peace settlement or a nuclear agreement.

Following Iran’s mid-July attacks on commercial vessels using alternative shipping routes along Oman’s coast, the Pentagon reinstated sanctions that had been promised under the MoU.
