The United States and Iran have officially begun implementing a memorandum of understanding (MOU) signed by President Donald Trump and Iranian President Masoud Pezeshkian. As of June 18, U.S. Central Command has lifted the blockade on Iranian ports, and Vice President JD Vance confirmed that 12.5 million barrels of oil moved through the Strait of Hormuz overnight. The reopening of the waterway serves as the first major test of the ceasefire, which includes a 60-day fee-free period for vessels before Tehran intends to implement transit charges. The Trump administration has formally submitted the interim document to Congress, detailing significant economic shifts including the proposed creation of a $300 billion recovery fund for Iran and the scrapping of several sanctions. Despite the diplomatic progress, U.S. Defense Secretary Pete Hegseth emphasized that military readiness remains high, stating that the U.S. is prepared to resume "ironclad" blockades and combat operations should Tehran fail to adhere to the terms of the agreement. Technical negotiations are set to transition to Switzerland, where officials will address the long-term status of Iran’s nuclear program. Regional partners, specifically Qatar, have expressed support for the MOU, describing it as a solid foundation for regional stability. The agreement's scope extends beyond direct U.S.-Iran hostilities, reportedly mandating a cessation of operations on all fronts, including Lebanon, in an effort to cool broader proxy conflicts across the Middle East.
