Executive Summary

“Where is the Supreme Leader?” This question has been repeatedly raised in the context of escalating tensions and the prospect of a direct military confrontation between Iran and the United States. In recent months, Ayatollah Ali Khamenei, the 86-year-old head of state, has appeared in public far less frequently, and reports suggesting that he may be operating from secure underground locations have intensified speculation. Some observers in the West interpret this reduced visibility as evidence of fear, vulnerability, or even a potential leadership vacuum, especially given his traditionally hands-on authoritarian style. However, the situation is more complex. As this paper argues, the Supreme Leader’s physical absence from the public sphere should not be equated with declining authority. Rather, his power continues to function through an extensive network of loyal institutions and intermediaries that operate largely behind closed doors, allowing him to maintain and even consolidate control over the regime’s core security and political structures despite heightened external threats.

Concerns about assassination appear to have shaped Khamenei’s public profile soon after Israel initiated targeted military operations against senior regime figures and strategic infrastructure in June 2025. He was reportedly moved to a secure bunker and remained largely absent from public and political life for nearly thirty days, a period that proved critical for the Islamic Republic. Since then, his appearances have been less frequent and more tightly managed, as renewed U.S.–Iran tensions have revived speculation about threats to his life and, in some commentary, even the possibility of abduction, drawing comparisons to scenarios previously discussed in relation to Nicolás Maduro in Venezuela.

His prolonged stay in secure underground bunkers has also carried symbolic consequences inside Iran. Among Iranians, this seclusion has led to the mocking nickname “Moushe-Ali,” or “Ali the Mouse,” a sarcastic reference to the perception that the Supreme Leader is hiding from danger rather than confronting it publicly. While such language circulates mainly in informal and opposition circles, it reflects how physical absence from the public eye can shape popular narratives and political ridicule, even when formal authority remains unchanged.

The absence of Khamenei, who holds absolute power in the Islamic Republic, has led to speculation that a decision-making vacuum may be emerging in Iran. Western reporting has suggested that this new status quo could lead to a paradigm shift in the Islamic Republic’s policymaking and a reshuffling among the elite. The Economist, for example, boldly asserted that Khamenei’s power was “diminishing” as a result of his “fading into the shadows.” The New York Times even claimed that in Khamenei’s absence, “politicians and military commanders were forming alliances and vying for power.” It suggested that Khamenei’s reduced presence may embolden other groups or factions within the regime, altering the regime’s confrontational stance toward the U.S. and Israel, a course Khamenei has pursued for more than three decades. More recently, an X account attributed to Israel’s Mossad claimed that Islamic Revolutionary Guard Corps (IRGC) commanders, Maj. Gen. Mohammad Pakpour and former Maj. Gen. Mohammad Bagher Ghalibaf, now speaker of the Iranian parliament, were “making decisions” independently of Khamenei.

Visible developments have reinforced this speculation. These include the appointment of Ali Larijani, a traditional conservative familiar to many Western diplomats, as secretary of the Supreme National Security Council, and the creation of a new Defense Council. They also include shifts in elite rhetoric, such as Hassan Rouhani’s call, for the first time, for a pause in nuclear enrichment, as well as recent statements by former Foreign Minister Javad Zarif promoting “a new approach rooted in domestic reform” and negotiation tied to stopping uranium enrichment.

Yet these signals should not be overinterpreted as evidence of a fundamental change in the Islamic Republic’s power structure. The reality is more nuanced. Behind the scenes, a dense and loyal network continues to safeguard the supreme leader’s power, ensuring that his hold on the regime remains firmly intact even when he is less visible in public or political arenas.

For more than three decades, the Bayt-e Rahbari (also referred to as the Bayt), or Office of the Supreme Leader, has been the single most important entity in the Islamic Republic’s policymaking. Despite its centrality and frequent references by Iranian observers, there is remarkably little public information about this secretive and complex institution and relatively little scholarly attention to it. Rooted in religious doctrine, the Bayt has allowed Khamenei not only to influence every major decision but also to personalize the key levers of power throughout the Islamic Republic. And contrary to what is visible on the surface, since the 12-day war, while the supreme leader himself may be absent from the public and political eye, he is exercising power through his Bayt, which has only been tightening its iron grip over the regime.

Drawing on original and primary Persian-language sources, including material obtained from within the regime, this research by United Against Nuclear Iran offers the first comprehensive English-language study of the Bayt (Office of the Supreme Leader), one of the most powerful and least understood institutions in the Islamic Republic. This paper examines the historical origins of the Bayt; reveals its intricate and clandestine structure and personnel; exposes how it ensures the supreme leader’s control over Iran’s military, political, economic, and cultural spheres; and examines its role during and after the 12-day war.
