Iran’s Supreme Leader Hands U.S. Strategy Control to IRGC Commander, Sidelining Diplomacy

Iran’s new Supreme Leader Mojtaba Khamenei has transferred control of U.S. policy to IRGC Commander Ahmad Vahidi, effectively removing the civilian government from decisions on American engagement and cementing hardline authority over Iran’s strategic direction, according to reports from within the Revolutionary Guards.^[1][2]

The move reflects a deliberate narrowing of decision-making authority in Tehran’s upper echelons. Khamenei, who assumed the supreme leadership in March 2026 following his father Ali Khamenei’s death, has consolidated power by routing U.S. strategy through the IRGC rather than through President Masud Pezeshkian’s administration or the Foreign Ministry. Vahidi, the new IRGC chief, now holds final authority on all matters relating to American policy – a concentration of military control over diplomatic channels that marks a significant departure from the institutional balance that characterized earlier administrations.^[3][4]

The assignment carries particular weight because it effectively terminates any ongoing negotiation track with Washington. Multiple reports indicate there are currently no active diplomatic channels between Tehran and the U.S., a sharp contrast to periods when even hardline-dominated governments maintained back-channel communication or allowed space for conditional talks.^[1][4] By vesting Vahidi with unilateral authority, Khamenei has institutionalized the hardline position: decisions about U.S. engagement will now flow through military rather than diplomatic apparatus.

This shift occurs alongside Khamenei’s public hardening. State media recently circulated an image of the new Supreme Leader writing a statement that “In the end, Israel will be destroyed,” signaling a rhetorical escalation that aligns with the institutional changes underway.^[1] The combination – hardline messaging paired with military control over American policy – suggests Khamenei is consolidating a faction within the regime that opposes negotiation and favors confrontation.

The sidelining of Pezeshkian’s government appears intentional and deliberate. Khamenei has already rejected a law proposed by the president regarding the Caspian Sea Convention, asserting that Iran will not relinquish its rights in the region.^[5] Ayatollah Bagher Haeri, a representative of Khamenei, has made clear that if Pezeshkian’s government attempts to manipulate the situation and announces resignation, Khamenei will accept it – a barely veiled threat that the president serves at the Supreme Leader’s pleasure.^[6] The transfer of U.S. policy to Vahidi represents another step in that consolidation, reducing the presidency to a subordinate role in matters of foreign strategy.

What this tells us about the regime’s stability calculus: Khamenei’s concentration of military authority over diplomacy suggests confidence in the IRGC’s ability to manage escalation without losing control, but also reflects anxiety about civilian voices within the government pushing for negotiation. By removing the president and Foreign Ministry from U.S. policy decisions, the new Supreme Leader is betting that military unity under Vahidi can hold the regime together better than contested decision-making. The risk is that removing diplomatic channels entirely eliminates pressure relief valves at moments of acute crisis – a calculation that may prove costly if miscalculation leads to direct confrontation.
