IRGC commander Rezaei will be taking over as secretary of Iran’s top security body amid talks over the Strait of Hormuz. Mohsen Rezaei, the former commander-in-chief of the Islamic Revolutionary Guard Corps (IRGC), has been appointed as the head of Iran’s top security body, which plays a crucial role in the country’s security and foreign policy. Rezaei takes over as secretary of the Supreme Security Council amid ongoing talks over the Strait of Hormuz, which Tehran has used as leverage during the months-long conflict with the US and Israel. He replaces Mohammad Bagher Zolghadr, who has been appointed as a political adviser to Supreme Leader Mojtaba Khamenei. The position was formerly held by Ali Larijani, who was assassinated in a US-Israeli strike in March. Here is what we know about Rezaei and his appointment. Who is Mohsen Rezaei? Rezaei, 71, headed the IRGC from 1981 to 1997. That period included the Iran-Iraq War of the 1980s, referred to in Iran as the “Sacred Defence”. Rezaei then went on to serve as a member of Iran’s Expediency Discernment Council, which resolves disputes over legislation between parliament and the Guardian Council. The Guardian Council is a separate body appointed by the supreme leader that vets candidates for elected political office in parliament, presidency and the Assembly of Experts. It’s also tasked with reviewing legislation to ensure compatibility with the constitution and Islamic law. Rezaei has placed high importance on Iran maintaining control of the Strait of Hormuz, a narrow waterway through which a fifth of global oil and gas pass. In July, he said control of the waterway was worth more than “dozens of atomic bombs”. Last week, he warned the US it would “face serious risks and casualties” if its blockade of Iranian ports continues. Iran has imposed a blockade on the strait in response to the US-Israel war launched in February, while the US has hit Tehran with a naval blockade in efforts to put economic pressure on the country. What do we know about his appointment? The Iranian president’s communications office announced on Sunday evening that President Masoud Pezeshkian had appointed Rezaei as secretary of the Supreme Security Council, Al Jazeera Arabic reported. On the same day, Khamenei issued a decree appointing Rezaei as his representative on the council, making special reference to his experience and to his being among the “pioneers of the Sacred Defence era” during the Iran-Iraq war – a reference that reinforced the presence of his military background in interpretations of the reasons for his selection.

What is the significance of his appointment? The Supreme Security Council is a key institution where the strategic considerations of the presidency, the foreign ministry, the armed forces and the security agencies intersect. Therefore, the identity of the council’s secretary carries significance that goes beyond his administrative powers, especially when the change in leadership coincides with an open war, faltering negotiations with the United States, and disputes over the terms of navigation and sovereignty over the Strait of Hormuz. Rezaei will bring military, economic and political experience to the role, Abas Aslani, a senior research fellow at the Tehran-based Center for Middle East Strategic Studies, told Al Jazeera. “They needed to have someone who can somehow synchronise different bodies of the government,” Aslani said. “Politically, he is not that much different from his predecessor on security, but the role he can play domestically, and being a balancing act in the country, is quite significant in this regard,” he added. Aslani added that Rezaei, as a former IRGC chief and member of Iran’s Expediency Discernment Council, will also play an important role in Tehran’s negotiations with the US. “I think it is important to have someone who is able to reach out to different factions and to talk to them, and that is why he has been picked,” he said. Rezaei’s appointment takes on an additional political dimension given his position during the 2024 presidential election, when he backed Mohammad Bagher Ghalibaf, placing him electorally closer to the conservative wing represented by Ghalibaf, the current parliament speaker and chief negotiator in talks with the US, rather than to the more hardline faction associated with Saeed Jalili, who was the runner-up against Pezeshkian. This positioning does not mean that Rezaei is a moderate figure, nor is a single electoral stance sufficient to judge his permanent alliances. But it shows that his position within the conservative camp does not necessarily coincide with that of Jalili and the forces most opposed to negotiations with the US. This position could give Rezaei room to manoeuvre among multiple parties: Pezeshkian’s government, which adopts a discourse more open to negotiation; the conservative camp linked to Ghalibaf; and the military and security forces with which Rezaei has historical ties dating back to his period as commander of the IRGC. What will be the implications of Rezaei’s appointment to the top security post? Analysts interviewed by Al Jazeera Arabic offered two main readings of the appointment. One sees it as a sign that military and security considerations are being prioritised amid war and tensions with the United States.
