The United States and Iran have reached a preliminary memorandum of understanding designed to ensure Iran never develops or acquires nuclear weapons. The MOU, reached in June 2026, comes after a period of heightened hostilities stemming from the 2025 conflict between the two nations.
President Trump, Vice President JD Vance, and Defense Secretary Pete Hegseth have all asserted that the agreement guarantees Iran will not attain nuclear weapon capabilities.
What the agreement actually covers
The MOU includes commitments from Iran to forgo nuclear weapons development entirely. It also addresses keeping the Strait of Hormuz, one of the world’s most critical oil shipping chokepoints, accessible to international traffic.
The agreement tackles Iran’s highly enriched uranium stockpiles, though the finer details of enrichment levels and verification mechanisms are being punted to follow-up talks over the next 60 days.
