President Donald Trump signed a Memorandum of Understanding with Iran at the Palace of Versailles on June 17, 2026, capping months of conflict with what amounts to the most significant US-Iran diplomatic breakthrough in decades. The signing took place during a dinner with French President Emmanuel Macron, lending the kind of cinematic backdrop that only a 17th-century French palace can provide.
The MOU, which took immediate effect, commits both nations to ending hostilities and reopening the Strait of Hormuz, one of the world’s most critical oil shipping chokepoints, without tolls. Iranian President Masoud Pezeshkian was among the signatories, confirming Iran’s commitment to cease military operations and pursue peace talks.
What the deal actually says
The agreement includes a 60-day extension period for negotiations specifically focused on nuclear issues and sanctions relief. Iran’s commitment not to pursue nuclear weapons sits at the center of the MOU, a stipulation that will sound familiar to anyone who followed the original Iran nuclear deal saga from the Obama era.
The signing replaced what had been a planned formal ceremony in Geneva, suggesting the parties wanted to move faster than scheduled. Timing it alongside the G7 Summit at Versailles gave the moment additional diplomatic weight, turning what could have been a bilateral footnote into a multilateral spectacle.
