Iran's Supreme National Security Council announced that Iran and the U.S. have agreed to end the war on all fronts [1].

This agreement marks a significant shift in geopolitical tensions between the two nations. The finalization of a memorandum of understanding (MoU) aims to formalize a cessation of hostilities and stabilize the region through a mutually agreed framework [1].

The announcement regarding the MoU occurred in March 2026 [1]. A spokesperson for the Supreme National Security Council said that the two countries have reached this agreement to end the conflict [1].

Parallel to these diplomatic developments, the council has undergone a leadership change. Mohammad Bagher Zolghadr was appointed as the new secretary of the Supreme National Security Council [2]. He replaces the late Ali Larijani [2].

While the MoU signals a move toward peace, internal Iranian dynamics remain centered on the country's highest authority. President Pezeshkian addressed the nature of these strategic decisions during the process. "The decision on war rests with the Leader," Pezeshkian said [1].

The transition of the council's secretary follows the death of Larijani. Reports regarding the circumstances of Larijani's death vary among international sources, though the Iranian government has moved forward with Zolghadr's appointment to ensure the continuity of the council's operations [2].

“"Iran and the United States have agreed to end the war on all fronts,"”

The finalization of an MoU between Iran and the U.S. suggests a tactical pivot toward de-escalation, though the emphasis on the Leader's ultimate authority indicates that the agreement remains subject to the internal ideological constraints of the Iranian leadership. The appointment of a new SNSC secretary amid these negotiations ensures administrative stability during a volatile transition period.
