Washington loves to believe that diplomacy is a straightforward game of incentives. You sit at a table, you offer sanctions relief, you get nuclear concessions. It is a neat, tidy, and logical sequence. It works in most places. It fails consistently in Tehran.
The reason for this failure is not just about the specific Iranian president in office or the current diplomatic team. It is because the real decision-making power in Iran does not sit in the presidential office. It sits in the shadow of the Supreme Leader. And right now, the name that keeps coming up in intelligence reports and back-channel conversations is Mojtaba Khamenei.
If you are trying to understand why US-Iran peace talks are stuck in a state of permanent delay, you have to look past the official spokespeople. You have to look at the man who is quietly managing the machinery of the state.
The Office of the Leader is the True Power Center
Most Western analysts focus on the elected government. They analyze speeches by the Iranian president or the foreign minister, hoping to find a hint of moderation or a shift in policy. This is a mistake.
In the Islamic Republic, the president is effectively a mid-level manager. They handle the bureaucracy, the budget, and the daily administration. They do not set high-level national security strategy. That authority belongs to the Office of the Supreme Leader, known as the Beit-e Rahbari.
This institution is not just an office. It is a parallel government. It controls the military, the intelligence agencies, and the state-run media. And for years, Mojtaba Khamenei has been described as a central figure in the management of this institution.
When diplomats deal with Iran, they are dealing with a subordinate. The real negotiators, the ones who decide whether a deal is acceptable, are behind the curtain. If the Beit is not interested in a rapprochement with the West, no amount of diplomatic effort from the president will change the outcome.
The Succession Question Changes Everything
Succession planning is the single biggest driver of hardline behavior in Tehran. Ali Khamenei is aging. The regime is obsessed with ensuring its survival after he is gone.
This is where the Mojtaba factor becomes impossible to ignore. There is significant speculation among regional observers that Mojtaba is being positioned as a potential successor or, at the very least, as the primary kingmaker for the next Supreme Leader.
If your goal is to succeed the current Supreme Leader, you cannot be seen as soft on the United States. You cannot support a deal that looks like capitulation. The revolutionary identity of the regime—its anti-American stance—is the currency of power inside the clerical establishment. If Mojtaba is associated with the hardline wing of the IRGC (Islamic Revolutionary Guard Corps), he needs the IRGC's backing to secure his future.
A deal with the United States, or even a meaningful dialogue, creates a massive political risk for anyone in the succession pipeline. It suggests that the regime is willing to trade its ideological purity for economic stability. For the hardliners, that is a trap. They would rather have a struggling economy and total control than a flourishing economy that requires them to bow to Washington.
Why the Hardliners Fear Engagement
We often hear the argument that Iran needs economic relief. That is true. Inflation is high, the currency is volatile, and the people are tired. Logic dictates that they should want sanctions lifted.
But logic assumes the regime prioritizes the welfare of the people over its own survival. That is a dangerous assumption.
The Iranian security state believes that opening up to the West is the first step toward a "velvet revolution." They look at history and see how engagement has led to internal loosening and, eventually, regime collapse. They do not view US diplomacy as a negotiation. They view it as a subversive campaign.
Mojtaba Khamenei and his circle are part of an generation that came of age during the Iran-Iraq war. They are hardened by conflict. They see the West not as a potential partner, but as an existential threat that uses diplomatic niceties to undermine the Islamic Republic from within.
When peace talks delay or stall, it is rarely due to a misunderstanding of the terms. It is because the hardline faction perceives the very act of talking as an opening for Western influence.
The Myth of the Moderate
For decades, the West has hunted for "moderate" factions in Iran. We pinned our hopes on Khatami. We pinned our hopes on Rouhani. Every single time, we were disappointed.
The problem was never the individuals. The problem is the structure. Even if a president wants to strike a deal, they require the blessing of the Supreme Leader. If the Supreme Leader’s inner circle—including his son—believes that a deal is a threat to their institutional power, the president is powerless to sign it.
This is why looking for a moderate shift is a waste of time. Instead of asking if the current president is a moderate or a hardliner, we should be asking about the internal consensus within the Office of the Leader. If the people managing that office see their power shrinking, they will shut down any diplomatic channel.
Stop Treating Diplomacy as a Policy Problem
The United States often treats the Iran issue as a policy challenge that can be solved with the right combination of sticks and carrots. They increase sanctions to force them to the table, then offer relief to keep them there.
But this does not address the internal politics of Tehran. If the individuals in the inner circle of the Supreme Leader view the negotiation as a threat to their personal or institutional status, they will choose the threat of sanctions over the threat of regime change.
Recognizing the influence of figures like Mojtaba Khamenei does not mean we have to stop talking. It means we have to stop expecting the talks to result in a grand bargain.
If the goal is to prevent a nuclear breakout or reduce regional tensions, the strategy must change. We have to stop betting on the idea that the Iranian government will suddenly decide that Western integration is good for them. They have decided it is bad for them.
A More Realistic Approach
If we accept that the current power structure in Tehran is fundamentally allergic to a long-term US-Iran peace deal, the strategy must shift from "trying to reach an agreement" to "managing the escalation."
- Ditch the Grand Bargain: Stop chasing a comprehensive deal. It is not on the table. The internal political costs for the Iranian leadership are too high.
- Focus on De-escalation: Prioritize specific, limited agreements that reduce the risk of direct conflict. Think of this as managing a rivalry rather than ending it.
- Recognize the Gatekeepers: Intelligence and policy focus must move away from the Ministry of Foreign Affairs and toward the Office of the Leader. That is where the actual decisions are made.
- Strengthen Regional Partnerships: Since direct diplomacy is likely to remain frozen, strengthening alliances with regional neighbors is the only way to check Iran’s influence.
We have spent years hoping for a change in Tehran. We have waited for the "moderates" to win or for the "economic pressure" to break the regime. Neither has happened. The reality is that the core of the regime—the unelected, shielded, and deeply conservative center—is currently in the driver's seat.
As long as that remains the case, the delays in peace talks aren't bugs in the system. They are features. The stagnation is intentional. It is the result of a power structure that prioritizes survival over everything else. Understanding that is the only way to avoid the constant cycle of disappointment that defines Western policy toward Iran.
