Iran Appoints Mohsen Rezaee to Lead National Security Council, Reshaping Power Dynamics

Iran has appointed Mohsen Rezaee as the new secretary of its Supreme National Security Council, signaling a strategic move to consolidate war management and negotiations under the Supreme Leader and the Revolutionary Guards establishment. The appointment, announced on July 18, 2026, aims to curb the influence of President Masoud Pezhkian and Foreign Minister Abbas Araghchi, while balancing against Parliament Speaker Mohammad Baqer Qalibaf, who led recent ceasefire talks with the United States in June.

Rezaee, 71, a veteran commander of the Revolutionary Guards during the Iran-Iraq War and a long-time political figure, replaces Mohammad Baqer Zolghadr, who served just over four months. Supreme Leader Mojtaba Khamenei also named Rezaee his personal representative on the council alongside hardliner Saeed Jalili. Zolghadr was reassigned as Khamenei’s political advisor, indicating the reshuffle is a power reorganization rather than a dismissal for failure.

Experts interpret Rezaee’s return as a sign of the entrenched influence of the old guard within Iran’s security apparatus, reinforcing the Revolutionary Guards’ dominance over policymaking. Analysts suggest the move is designed to counterbalance Qalibaf’s moderate approach and limit Pezhkian and Araghchi’s efforts toward a diplomatic settlement with the U.S. While Qalibaf publicly welcomed Rezaee’s appointment, tensions between these key figures may intensify due to competing political ambitions.

The Iranian Foreign Ministry’s response underscored the growing authority of the National Security Council, with spokesperson Esmail Bakaai emphasizing coordination with the council rather than individual leadership in negotiations. This shift may tighten oversight on peace talks and restrict Pezhkian and Araghchi’s ability to make concessions without Revolutionary Guard approval.

The council, which includes senior government, military, and intelligence officials, plays a central role in Iran’s policy toward the U.S. and Israel. It approved a ceasefire memorandum in June that quickly unraveled amid disputes over control of the Strait of Hormuz. Any future agreements on the strait or ceasefire will require council approval and ultimately the Supreme Leader’s consent. The appointment of Rezaee could signal Tehran’s intent to impose stricter conditions on reopening the strait and ending hostilities, including compensation, sanctions relief, and recognition of Iran’s status.

This internal power struggle among Rezaee, Qalibaf, Pezhkian, and Araghchi complicates the clarity of Iran’s negotiating stance and may determine whether Tehran pursues a diplomatic resolution or continues a protracted conflict around the Strait of Hormuz.
