A shift in Iran’s internal power structure may be reshaping both its diplomacy and military strategy. According to the Institute for the Study of War, the Islamic Revolutionary Guard Corps (IRGC) is playing an increasingly dominant role in negotiations with the United States, alongside its established control over military operations. Under the influence of Ahmad Vahidi, IRGC leadership is believed to be directly overseeing discussions that were traditionally handled by civilian diplomats. Recent talks in Islamabad included the presence of senior IRGC commanders, highlighting a shift toward a more security-driven negotiation framework. On the ground, this shift is reflected in developments around the Strait of Hormuz, where operational decisions appear to be aligned with IRGC priorities rather than diplomatic signals. The evolving dynamic suggests that Iran’s negotiation process is no longer confined to formal diplomacy, but increasingly shaped by military considerations and parallel centres of power.
