US President Donald Trump signed the much-awaited Memorandum of Understanding (MoU) on the much-awaited US-Iran peace deal during a dinner with French President Emmanuel Macron at the G7 summit in Versailles on Thursday. As Trump sat near Macron, US Secretary of State Marco Rubio handed him the agreement. “It wasn’t easy,” Trump remarked before putting pen to paper. After signing the document, Trump picked it up and showed the agreement to those gathered in the room.“President Trump signed the agreement between Iran and the United States tonight in Versailles. This agreement paves the way for lasting peace and allows the reopening of the Strait of Hormuz. This is an important step in the right direction for our compatriots that will soon enable a reduction in energy prices,” Macron said in a post on X, welcoming the agreement.The agreement was signed on behalf of Iran by its President Masoud Pezeshkian.The development represents a major step toward reducing tensions after several months of escalating hostilities in the region, including military conflicts involving Iran, Israel and the United States. The agreement, officially titled the “Islamabad Memorandum of Understanding between the United States of America and the Islamic Republic of Iran”, outlines a ceasefire, expanded economic cooperation, sanctions relief and a roadmap for future negotiations on Iran’s nuclear program.It remained unclear whether the signing initiated a 60-day window for negotiations aimed at reaching a final agreement. Questions also remain about how Trump’s signature on the document at Versailles differed from his previous digital approval of the deal on Sunday. Versailles has been the site of many historic treaties throughout history, many of them involving the conclusion of wars and territorial disputes. The most notable was the Treaty of Versailles of 1919, which formally ended World War I. Its punitive terms on Germany have been cited by some historians as contributing to the political and economic conditions that later helped lead to World War II.
