U.S. President Donald Trump and Iranian President Ebrahim Raisi signed a memorandum of understanding on June 18, 2026 [1], to end hostilities.

The agreement aims to stabilize the Middle East by reopening the strategic Strait of Hormuz and easing sanctions on Iran [1, 2]. This move seeks to prevent further escalation in a region marked by ongoing military conflict.

The two leaders signed the 14-point [3] deal at the Palace of Versailles in France [4]. French President Emmanuel Macron was present for the ceremony [4]. The memorandum focuses on a ceasefire, and the restoration of maritime trade routes through one of the world's most critical oil transit points.

NBC News said the interim agreement declares an intent to bring about an "immediate and permanent termination of military operations" [2]. While some reports describe the goal as ending the broader war in the Middle East, others specify the termination of military operations within the U.S.-Israeli war with Iran [1, 2].

The deal involves a complex exchange of concessions. The U.S. intends to lift specific sanctions to facilitate economic stability in Iran [2]. In return, Iran has agreed to terms regarding the reopening of the Strait of Hormuz to ensure the free flow of global commerce [1, 2].

This diplomatic breakthrough follows a period of high tension and military engagement. The 14-point [3] framework serves as a roadmap for a more permanent resolution between the two nations [1, 3].

The interim agreement declares an intent to bring about an "immediate and permanent termination of military operations".

The signing of this memorandum represents a significant diplomatic shift, prioritizing the stability of global energy markets by securing the Strait of Hormuz. By moving toward a permanent termination of military operations, the U.S. and Iran are attempting to decouple regional proxy conflicts from direct state-on-state warfare, though the success of the deal depends on the verifiable lifting of sanctions and the sustained absence of military provocation.
