The U.S. and Iran are scheduled to formally sign a peace memorandum of understanding in Geneva, Switzerland, on June 19, 2026 [3].
The agreement aims to end a conflict that has lasted three months [2]. A successful resolution would stabilize the Strait of Hormuz, a critical global shipping lane, and establish formal guarantees regarding Iran's nuclear ambitions.
President Donald Trump (R-WY) said that Iran has provided guarantees that it will not develop nuclear weapons and that the two nations are close to a very good deal [2]. The negotiations follow a period of intense military activity and diplomatic maneuvering, including travel by Iranian officials to Qatar [1].
Despite the pending agreement, tensions remained high throughout late May. Iranian officials in Tehran said that U.S. strikes on their boats and missile launch sites were a flagrant violation of the ceasefire [1]. These clashes occurred as both sides attempted to finalize the framework of the memorandum.
Naval friction continued in the Strait of Hormuz. Trump said that three U.S. Navy destroyers passed through the strait under fire, though the American warships were not hit [1].
While some reports identify the agreement as the Islamabad Memorandum of Understanding, other sources describe it more broadly as a U.S.-Iran memorandum of understanding [1]. The final document is expected to address the cessation of hostilities, and the prevention of nuclear proliferation.
“Iran has provided guarantees that it will not develop nuclear weapons, and we are close to a very good deal.”
The scheduled signing in Geneva represents a critical attempt to pivot from active kinetic warfare to a diplomatic framework. However, the continued military strikes in the Strait of Hormuz suggest that a 'cold peace' may be the immediate result rather than a full reconciliation. The durability of the deal depends heavily on whether the U.S. can verify the nuclear guarantees provided by Tehran.
