US-Iran Diplomatic Process Expires With No Replacement and No Talks Underway

A June 2026 US-Iran memorandum of understanding to end hostilities expired August 17 with no permanent agreement. Trump declared the deal "over" on July 7 and the US struck Iran again July 8. No negotiations are underway. The collapse coincides with reported Iranian considerations of striking US military sites in Europe and NATO's pledge to defend all allies.
