The IRGC increasingly wields the true power in Iran, while the Supreme Leader's role is becoming more symbolic. He serves as a "sacred totem" and a "lightning rod for criticism" but is ultimately a facilitator of IRGC influence rather than a check on its power.

While the previous Supreme Leader's caution kept Iran from weaponizing, his death and the rise of a leader closer to the IRGC increases the likelihood of a push for a nuclear bomb. The new leadership is more risk-tolerant and convinced a nuclear deterrent is necessary for survival.

While Mojtaba Khamenei is now supreme leader, his actual control is questionable. Iran is navigating a wartime transition with leaders in hiding, allowing factions like the Revolutionary Guard to vie for influence and pull the strings, suggesting a period of fragmented authority.

Iran's leadership projects regional strength, fostering national pride that makes compromise seem weak. However, this belligerence is a facade for a devastated domestic economy racked by sanctions, corruption, and war. This creates a fundamental tension: while they act tough, their long-term survival necessitates a diplomatic arrangement with the very enemies they confront.

Engaging only with formal Iranian negotiators while ignoring hardliner factions like the Islamic Revolutionary Guard Corps (IRGC) leads to failed diplomacy. The IRGC is the true power center in Iran, and any agreement made without their buy-in is unlikely to be honored or effective, as they control the actual military assets.

Leaders often assume that applying pressure will force an opponent to the negotiating table. This strategy can fail when the adversary operates under a different logic or, as with Iran's decentralized military, when there is no single authority left to negotiate with, revealing a critical cognitive bias.

Iran is transitioning into a 'Third Islamic Republic,' a phase where the military and security bureaucracy, not the clerics, hold dominant power. This shift marks a state where the military elite controls political and economic levers, bringing Ayatollah Khamenei's long-term project to fruition.

The assassination of Iran's old, restrained leadership paved the way for a new generation of commanders. This new group believes the previous strategy of restraint led to war, and that only aggressive, disproportionate responses can serve as an effective deterrent against the U.S. and Israel.

The US administration believed it could decapitate Iran's leadership and install a friendly faction, replicating its 'Venezuela model.' This strategy collapsed in the opening hours of the war because the potential successors the US counted on were killed alongside the Supreme Leader.
