Why Mohsen Rezaei’s Appointment as Iran’s Security Chief Matters

Iran has appointed former Islamic Revolutionary Guard Corps (IRGC) commander Mohsen Rezaei as secretary of the Supreme National Security Council (SNSC), placing a veteran military figure at the centre of the country’s security and foreign-policy decision-making.
The appointment comes at a highly sensitive moment, with Iran facing intense pressure from the United States and Israel, ongoing tensions over the Strait of Hormuz, and uncertainty surrounding potential negotiations with Washington.
Rezaei replaces Mohammad Bagher Zolghadr, who has moved into the role of political adviser to Supreme Leader Mojtaba Khamenei. The post was previously held by Ali Larijani, who was killed in a US-Israeli strike in March.

Who Is Mohsen Rezaei?
Rezaei, 71, led the IRGC from 1981 to 1997, including throughout the Iran-Iraq War, known in Iran as the “Sacred Defence”.
After leaving the IRGC command, he became a member of Iran’s Expediency Discernment Council, an influential body that helps resolve disputes between parliament and the Guardian Council.
His military background has remained central to his political identity. Rezaei has repeatedly stressed the strategic importance of the Strait of Hormuz, a vital global energy route through which a significant share of the world’s oil and gas shipments pass.
In July, he said control of the waterway was more valuable than “dozens of atomic bombs”. More recently, he warned that continued US pressure and the blockade of Iranian ports could expose Washington to serious risks and casualties.

Why Was Rezaei Chosen?
Iranian President Masoud Pezeshkian’s communications office announced Rezaei’s appointment on Sunday. Supreme Leader Mojtaba Khamenei also appointed him as his representative on the Supreme National Security Council.
The emphasis on Rezaei’s experience during the Iran-Iraq War highlighted the importance of his military credentials.
His selection also reflects the increasingly complicated environment in which Iran’s leadership is making decisions. The SNSC brings together the presidency, foreign ministry, armed forces and security institutions, making its secretary an important coordinator between competing centres of power.
According to Tehran-based analyst Abas Aslani, Rezaei’s broad political, military and economic experience could help coordinate different parts of the Iranian state.
His longstanding connections across Iran’s political and security establishment could also make him an effective intermediary between competing factions.

A Military Figure at the Centre of Diplomacy
One of the most important aspects of Rezaei’s appointment is the possibility that he could influence Iran’s approach to negotiations with the United States.
Rezaei is not considered a moderate figure. However, his political position has not always aligned with the most hardline elements of Iran’s conservative establishment.
During the 2024 presidential election, he supported parliament speaker Mohammad Bagher Ghalibaf rather than Saeed Jalili, whose political camp has generally taken a tougher position towards negotiations with Washington.
That history could give Rezaei some room to operate between President Pezeshkian’s government, Ghalibaf’s conservative political camp and Iran’s military and security establishment.
Could His Appointment Help Future US-Iran Talks?
There are two competing interpretations of Rezaei’s appointment.
The first is that Iran is placing greater emphasis on military and security considerations as tensions with Washington intensify. From this perspective, choosing a former IRGC commander signals that Tehran is preparing for a prolonged confrontation and wants its security establishment to have greater influence over national policy.
The second interpretation is more complicated.

Rezaei’s military credentials could actually make it easier for Iran’s leadership to pursue a negotiated settlement if one becomes possible. A former IRGC commander could have greater credibility among hardline factions and therefore face less criticism for supporting an agreement with Washington.
In other words, his role may not simply be about making Iran’s negotiating position tougher. His presence could also provide political cover for difficult compromises.
A Possible Shift in Iran’s Security Strategy
International relations professor Mohsen Farkhani offers a more security-focused interpretation.
He argues that Rezaei’s appointment may reflect a broader shift towards a tougher Iranian security doctrine following the failure of diplomacy and Tehran’s accusations that Washington violated previous understandings.
Rezaei’s experience in conventional warfare, combined with Iran’s longstanding reliance on asymmetric military tactics, could reinforce a strategy focused on deterrence through retaliation and sustained pressure.
Under this approach, Tehran could adopt a less flexible position towards the United States, particularly over the Strait of Hormuz and other issues connected to national sovereignty.
However, Rezaei’s appointment does not mean that he will independently determine Iran’s foreign or security policy. The Supreme National Security Council remains a coordinating institution operating under the authority of the supreme leader, whose decisions carry the ultimate weight.

What Does His Appointment Mean for Iran?
Ultimately, Rezaei’s appointment sends a significant political and strategic message.
It places a former IRGC commander at the heart of Iran’s national security decision-making at a time of war, economic pressure and diplomatic uncertainty.
For some analysts, the move indicates that Tehran is preparing for a harder and potentially prolonged confrontation with Washington.
For others, Rezaei’s deep ties to Iran’s military establishment could give the leadership greater freedom to negotiate without appearing weak to hardline constituencies.
The significance of his appointment, therefore, may lie less in whether Rezaei is simply “hardline” or “moderate” and more in his ability to connect Iran’s military establishment, political factions and diplomatic strategy.
His selection could ultimately strengthen Iran’s position for confrontation—or provide the domestic political cover needed for a difficult agreement with the United States.
