President Donald Trump and representatives of Iran signed a peace protocol on June 17, 2026 [1], to end hostilities in the Middle East.

The agreement marks a significant shift in diplomatic relations between the two nations. It seeks to establish a broader cease-fire by addressing nuclear proliferation and resuming formal negotiations.

The protocol was finalized at the Château de Versailles [2]. Under the terms of the agreement, Iran has committed to diluting its enriched uranium [3]. This move is intended to reduce the risk of nuclear escalation in the region.

"We have reached a historic agreement to end the hostilities in the Middle East," Trump said [4].

Reports differ on the physical nature of the signing. Some accounts state Trump signed the protocol in person at Versailles alongside French President Emmanuel Macron [1]. Other reports indicate the signing was conducted remotely [5], while a spokesperson for the Islamic Republic of Iran confirmed an electronic signature of the protocol [6].

French President Emmanuel Macron welcomed the development. "Emmanuel Macron salutes this moment of peace," a statement reported by Ouest-France said [1].

The deal aims to stabilize the region by replacing military tension with a structured diplomatic framework. The commitment to dilute uranium serves as a primary verification step to ensure compliance with the peace terms [3].

"We have reached a historic agreement to end the hostilities in the Middle East."

This protocol represents a high-stakes attempt to pivot from a policy of maximum pressure to one of diplomatic containment. By securing a commitment to dilute enriched uranium, the U.S. seeks a tangible reduction in Iran's nuclear capabilities in exchange for a cease-fire, potentially altering the security architecture of the Middle East.
