President Donald Trump said on August 17 that he has no definitive timetable for ending the nearly six-month U.S.-Iran war, and a disputed June memorandum of understanding with Tehran that was meant to structure 60 days of talks has now expired without a comprehensive agreement. The framework, described as covering the reopening of the Strait of Hormuz, about $24 billion in frozen Iranian assets and Iran's nuclear program, is effectively dead after Washington rejected Tehran's push for an extension and both sides blamed each other for the collapse. The breakdown leaves a key diplomatic channel closed even as the conflict continues to center on oil-market stability, sanctions pressure, maritime security and the risk of wider escalation around one of the world's most important energy chokepoints.
