The shadow of Ali Khamenei looms large over Iran, but the shadow behind him is getting longer every day. For decades, the world watched the Supreme Leader manage a delicate balancing act between the Islamic Republic’s warring factions. People used to call him a "moderate" in the early days. That sounds like a joke now, doesn't it? But compared to his second son, Mojtaba, the elder Khamenei might actually look like a diplomat.
If you're trying to understand where Iran is headed, you have to stop looking at the presidency. That office is a revolving door. The real power play is happening in the corridors of the "Beit-e Rahbari"—the Office of the Supreme Leader. This is where Mojtaba Khamenei has spent twenty years building a shadow state that is younger, meaner, and far more ideologically rigid than his father’s generation.
The transition from Ali to Mojtaba wouldn't just be a family affair. It would be a shift from a clerical autocracy to a military-security junta.
The Myth of the Moderate Father
It’s easy to mislabel Ali Khamenei. When he took power in 1989, he wasn't the first choice. He didn't have the religious credentials of Khomeini. To survive, he had to be a master of the "middle path." He played the reformists against the hardliners for thirty years. He allowed figures like Mohammad Khatami and Hassan Rouhani to hold the presidency because he needed them to interface with the West and manage the economy.
Ali Khamenei’s power is rooted in traditional clerical networks. He cares about the appearance of religious legitimacy. He balances the bazaaris (the merchant class) with the Basij (the paramilitary). He’s a cautious man. Every move he makes is calculated to ensure the survival of the system, even if it means slow-walking reforms he hates.
But Mojtaba? He doesn't care about the balancing act.
Mojtaba and the Rise of the Security State
Mojtaba Khamenei represents a different breed of Iranian leader. He came of age during the Iran-Iraq War, but his real "battlefield" was the 2009 Green Movement protests. While his father was hesitant to completely crush the opposition early on, Mojtaba reportedly took the reins of the crackdown.
Reliable reports from defectors and analysts at the Foundation for Defense of Democracies suggest Mojtaba was the bridge between the Supreme Leader’s office and the Intelligence Organization of the Islamic Revolutionary Guard Corps (IRGC). He didn't just want to stop the protests. He wanted to liquidate the reformist movement entirely.
Here is the fundamental difference. Ali Khamenei uses the IRGC as a tool. Mojtaba is the IRGC.
He’s spent years purging the old guard clerics who might oppose him. He doesn't seek consensus in the Assembly of Experts. He seeks loyalty through the security apparatus. If Ali Khamenei is the "Grand Ayatollah" playing politics, Mojtaba is the "Chief Executive" of a police state.
The Deep Divide in Foreign Policy
You see the difference most clearly in how they view the outside world. Ali Khamenei is a classic anti-imperialist. He hates the United States, but he understands the "Heroic Flexibility" required to sign a nuclear deal when the economy is screaming. He’s a product of the Cold War.
Mojtaba is a product of the "Resistance Axis" at its most militant.
- Ali's Approach: Use proxies to create leverage for negotiations.
- Mojtaba's Approach: Use proxies to expand the border of the revolution permanently.
Observers within the International Crisis Group have noted that Mojtaba’s circle is far more comfortable with Iran being a "pariah state" than his father is. They don't want a deal with the West. They want an "Economy of Resistance" that is completely decoupled from the dollar. They see any opening to the West as a Trojan horse for regime change.
The Clerical Legitimacy Gap
There’s a huge problem for Mojtaba, though. He’s not a high-ranking cleric. In the Shiite hierarchy, you can't just inherit the title of Supreme Leader like a Saudi prince. You need religious "Marja" status.
Ali Khamenei struggled with this for years. He was "promoted" to Ayatollah overnight to fit the job description. Mojtaba is trying to do the same thing. For the last decade, he’s been teaching "Kharij" (advanced) jurisprudence classes in Qom. It’s a transparent attempt to build a religious resume.
But the senior clerics in Qom don't respect him. They see him as a political interloper. This is why a Mojtaba-led Iran would be more violent. When a leader lacks religious legitimacy, they replace it with raw force. He won't lead through "fatwas" as much as he will lead through the "Evin Prison" system and the IRGC’s "Sarab" intelligence units.
What Happens When the Handover Occurs
The succession won't be a clean vote. It’ll be a crisis.
We’ve seen hints of this already. Look at the way Ebrahim Raisi was positioned before his helicopter crash in 2024. Many saw Raisi as the "stalking horse" for Mojtaba—a loyalist who would keep the seat warm or provide a veneer of institutional process. With Raisi gone, the path is shorter but much more exposed.
If Mojtaba takes over, expect three things immediately. First, a total purge of the remaining "moderate" elements within the Iranian Foreign Ministry. Second, a massive increase in funding for the IRGC’s cyber and domestic surveillance wings. Third, an end to any pretense of nuclear "transparency."
How to Track the Transition
You don't need to be an intelligence officer to see the signs. Keep your eyes on the "Setad"—the Execution of Imam Khomeini’s Order. This is a multi-billion dollar conglomerate controlled directly by the Supreme Leader.
Reports suggest Mojtaba has gained significant oversight of these assets. Money is the ultimate indicator of power in Tehran. If the "Setad" and the "Bonyads" (charitable foundations) start shifting their boards to include Mojtaba’s war buddies from the "Habib Battalion" (his personal IRGC unit), the deal is done.
The international community keeps hoping for a "thaw" in Tehran. That’s a fantasy. As long as the son’s influence grows, the frost only gets thicker. You aren't looking at a continuation of the father’s policies. You're looking at the birth of a more aggressive, less predictable, and far more insular Iranian state.
Stop waiting for a reformer to save the day. The real power struggle is over, and the hardliners won. The only question left is how much the rest of the world is willing to lose before they realize the "Moderate Khamenei" era was as good as it was ever going to get.
Watch the appointments in the IRGC's Intelligence Organization over the next six months. If Hossein Taeb’s protégés start filling senior roles, Mojtaba has effectively already seized the throne. Get ready for a much darker version of the Islamic Republic.
