Iran's Islamic Revolutionary Guard Corps (IRGC) has reportedly seized control of the nation's critical decision-making processes. Operating with significant autonomy and answering directly to the Supreme Leader, the IRGC's hardline approach appears to be sidelining civilian leadership amid ongoing conflict.

According to US intelligence assessments, IRGC commander Ahmad Vahidi is now making military and political decisions alongside Supreme Leader Mojtaba Khamenei. Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi reportedly require IRGC approval for their decisions. Vahidi has indicated that critical positions must be managed by the Revolutionary Guards under wartime conditions.

President Masoud Pezeshkian has been prevented from making key choices, including being compelled to appoint Mohammad Bagher Zolghadr as secretary of the Supreme National Security Council following IRGC demands. This appointment occurred despite objections from civilian officials and followed the death of Zolghadr's predecessor.

In a clear demonstration of the IRGC's authority, Foreign Minister Araghchi's announcement to reopen the Strait of Hormuz to commercial shipping was immediately overruled by the IRGC, which declared the strait closed again the following day.

The IRGC, established in 1979, was built on revolutionary zeal and ideological loyalty, designed for guerrilla tactics and asymmetric warfare. Its influence grew significantly during the Iran-Iraq War and through its Quds Force, which has supported groups like Hezbollah and provided military aid to Russia. The IRGC has also become a major economic actor, expanding its reach both within Iran and internationally.

Following heavy losses and leadership changes, including the deaths of key commanders, Brigadier General Ahmad Vahidi assumed command of the IRGC. Vahidi has a history as a former IRGC Quds Force commander and has held civilian posts. He also faces charges in Argentina for the 1994 AMIA Jewish Community center attack.

Despite challenges, the IRGC has maintained its operational capacity and influence, disrupting global markets by blocking the Strait of Hormuz. Analysts suggest a shift from a cleric-dominated system to a more IRGC-centric power structure, with the organization redefining its role beyond traditional clerical rule.
