Beyond the Supreme Leader: Reshaping Iran’s Domestic Order and the Balance of Power in the Middle East

The hypothetical absence of Iran’s Supreme Leader can be understood as a potentially pivotal moment, though not necessarily as an automatic collapse of the regional balance of power. Since the 1979 revolution, the Iranian political system has not been constructed around a single individual; rather, it rests on a complex institutional–security–ideological architecture in which power is distributed among the religious leadership, constitutional institutions, and security bodies-most notably the Islamic Revolutionary Guard Corps (IRGC). While the position of the Supreme Leader represents the apex of strategic decision-making, the system’s design has incorporated mechanisms intended to ensure continuity during periods of leadership transition or absence.

This paper seeks to examine whether the absence of Iran’s Supreme Leader would constitute a structural turning point in the nature of the Iranian system or merely a leadership transition within an institutional framework capable of sustaining itself. It also aims to assess the implications of such a development for the regional balance of power, in light of three principal variables: the internal configuration of authority, economic pressures, and the behavior of regional middle powers.

The absence of a figure of Ali Khamenei’s stature would not necessarily lead to the disintegration of Iran’s regional influence. Instead, it may trigger an internal redistribution of decision-making authority and potentially elevate the role of the military–security establishment more visibly. Iran’s regional influence is rooted in several key components: symbolic leadership, an extensive network of alliances and non-state actors, and a system of unconventional deterrence that has evolved over decades. Such a network does not simply disappear with the absence of its political head; rather, it enters a phase of internal repositioning and organizational recalibration.

From this perspective, any transition at the apex of power is more likely to reshape internal balances than to trigger an immediate collapse of Iran’s regional influence. Iran’s future will not be determined by external will-regardless of the intensity of international pressure-but will instead emerge largely from the internal dynamics of contestation between competing centers of authority and the demands of society. According to numerous social analyses, what many Iranians seek today cannot be reduced to the overthrow of the regime or the reproduction of an idealized democratic model. Rather, it centers on restoring a normal pattern of life, ensuring the provision of services, safeguarding basic freedoms, and reducing state interference in the details of everyday life. These internal dynamics will inevitably influence the type of leadership that may emerge in the post-transition phase.

Within this context, several possible trajectories can be envisaged:

1. The first scenario involves the gradual retreat of ideological discourse, leaving a vacuum that may be filled by a rising form of nationalism and a strong political figure who mobilizes narratives of restoring national dignity and state authority in order to consolidate the system. Under this model, power would become more centralized, and legitimacy would be reformulated on a national rather than a revolutionary–religious basis. The plausibility of this scenario derives in part from the nature of the Islamic Revolutionary Guard Corps (IRGC) itself, as a security elite capable of evolving into a governing political class should the necessary institutional conditions arise.
2. A second scenario envisions the military establishment transforming from an influential actor within the state into a directly-or quasi-directly-governing authority. In this trajectory, religious discourse would gradually be replaced by a nationalist–security narrative emphasizing stability, order, and discipline. While this path may appear plausible given the organizational weight of the IRGC, it also faces significant internal challenges. The Guard is not a single cohesive bloc but rather a network of overlapping factions and interests. Moreover, for segments of Iranian society, its image has become associated less with institutional competence than with corruption and economic privilege.
3. Alongside these models, there remains the possibility of what might be described as an “unresolved transition”-a prolonged period of fragility in which the system neither collapses nor rapidly consolidates around a new formula of authority. In such a scenario, power may become distributed among multiple institutions, while internal competition persists until a new equilibrium gradually takes shape. This possibility aligns with the inherently hybrid character of the Iranian system, which does not allow for a rapid settlement in favor of any single actor without a complex process of internal renegotiation.

Potential pathways of transition cannot be understood in isolation from the economic factor as a major source of structural pressure. The Iranian economy has been experiencing high inflation, currency depreciation, and a decline in purchasing power, compounded by the prolonged effects of international sanctions. In such environments, leadership transition becomes a comprehensive test of legitimacy, where ideological considerations intersect with the everyday social and economic pressures faced by society.

If the transition period coincides with economic instability, the new leadership may be inclined to reduce external risks and absorb tensions in order to safeguard internal stability. Conversely, if economic pressure is perceived as threatening elite cohesion, the leadership may resort to limited escalation as a tool to re-consolidate the domestic front. In this sense, the economy shifts from being a background condition to becoming a direct determinant of foreign policy behavior.

Each scenario is therefore less tied to a specific individual than to a broader pattern of leadership. The institutional nationalist scenario would require a pragmatic figure with extensive institutional experience, capable of addressing the state through the language of sovereignty and stability rather than the rhetoric of revolution. Figures who combine security backgrounds with parliamentary or executive experience could fit such a profile-for example, Ali Larijani, often viewed as an institutional actor rather than a confrontational ideological mobilizer.

By contrast, the explicit militarization scenario would involve the center of gravity shifting toward the hard security core of the regime, whereby the military establishment moves from a position of influence to one of direct leadership. In this context, personalities with direct military backgrounds represent clear examples of this leadership pattern, such as Esmail Qaani, commander of the Quds Force, whose transnational operational experience reflects a model of leadership grounded in security discipline and the management of regional networks of influence. Similarly, the leadership style represented by Ebrahim Raisi during his presidency reflected an approach emphasizing institutional rigidity and the primacy of a disciplined state over flexible political discourse.

In contrast, the institutional fluidity scenario assumes the emergence of a transitional consensus figure who lacks a strong independent base but enjoys relative acceptance across different centers of power within the system-whether religious, security, or economic. This trajectory could take the form of selecting a clerical figure with limited popular visibility but acceptable to the Assembly of Experts, or a more cautious internal transition that preserves elite balances without producing a sharp transformation. Such a scenario might materialize through the emergence of a religious–institutional figure such as Sadeq Amoli Larijani, an executive–administrative figure like Mohammad Mokhber, or a seminary–institutional personality with a quieter presence within the decision-making structure such as Alireza Arafi. In this case, the phase would be managed as a conservative transition aimed at preserving elite equilibrium until a clearer center of gravity emerges within the system.

At the regional level, however, none of these scenarios would automatically produce a lasting disruption in the balance of power. The United States or Israel might temporarily benefit from a moment of uncertainty, yet the regional environment is no longer governed by a simple bipolar logic. Several regional actors pursue flexible hedging strategies, while international powers such as Russia and China have a clear interest in preventing the emergence of stable dominance by any single actor.

During moments of regional uncertainty, some analyses assume that military superiority or international political backing is sufficient to translate opportunity into durable hegemony. Yet comparative experience in the Middle East suggests a fundamental distinction between deepening control and producing sustainable hegemony. In the West Bank, for instance, Israel already possesses an advanced structure of security and administrative control-particularly in areas classified as Area C-and operates through gradual legal and planning mechanisms aimed at reshaping geography, property ownership, and the real estate market. Such processes may accelerate during periods of international distraction, but they do not automatically translate into stable comprehensive annexation, since their structural costs-most notably demographic, political, and security-related-extend beyond the calculations of the moment.

The more precise question, therefore, is not whether the balance will collapse, but what type of balance will emerge after the transition period, and how the rules of regional engagement will be reconfigured.

Over the past decades, the Iranian system has engineered a distinctive pattern of conflict management: asymmetric deterrence, escalation management through proxies, and extensive reliance on non-state actors within a flexible and transnational network of influence.Top of Form

From this perspective, the absence of supreme leadership could lead to two contrasting strategic trajectories:

• The first trajectory involves the rationalization of regional behavior. In this scenario, the new leadership-whoever it may be-would likely seek to reduce external risk and concentrate on reorganizing domestic affairs, particularly if the transition coincides with economic or political pressures. Such a path could lower the level of regional friction and redefine the priorities of Iranian foreign policy, shifting from a project centered on the expansion of influence to one focused on the stabilization and preservation of the regime.
• The second trajectory would involve short-term escalation aimed at demonstrating continuity. In the literature on security and regime stability, some systems facing moments of transition tend to “externalize the crisis” in order to consolidate domestic cohesion. This may involve activating indirect deterrence mechanisms or raising the level of operational signaling across regional arenas. Such behavior should not necessarily be interpreted as an expression of surplus strength; rather, it often reflects the need to signal that the center of decision-making authority remains intact. Here lies the paradox: leadership transition may temporarily increase the level of risk-taking before the system settles into a new equilibrium.

Conclusion

It would be misguided to assume that the absence of the leader would automatically lead to systemic disintegration. Iran is not a purely personalist structure; rather, it rests upon a cohesive institutional–security architecture. Instead of collapse, what may emerge is what could be described as “security hardening”-a shift in the center of gravity toward the military establishment and the prioritization of caution and rigidity over political pragmatism. Under such a scenario, Iran would not necessarily weaken; instead, it could evolve into a more centralized structure that is less open to negotiation and characterized by stronger but less flexible deterrence.

More importantly, because the regional system does not operate according to a classical bipolar structure, the balance of power cannot be reduced to the interaction between Tel Aviv and Tehran alone. Alongside them exist regional actors pursuing flexible hedging and balancing strategies, while international powers such as Russia and China do not view the emergence of stable unilateral hegemony in the Middle East with comfort. Consequently, any temporary disruption in the balance of power would inevitably trigger corrective responses from other actors, either through strengthening their own influence or through supporting alternative arrangements.

The more consequential transformation may therefore lie in Iran’s potential shift from a “pivot state” model-in which influence projection constitutes a central strategic objective-to a “system-preservation state” model, one that prioritizes domestic stability and seeks to reduce the costs of external extension. Should this scenario materialize, the region may not witness permanent escalation; rather, it may undergo a quiet yet deeply consequential process of rebalancing.

The potential transition at the apex of Iran’s political hierarchy thus goes beyond the question of who the next leader will be. It concerns a deeper redefinition of the relationship between the domestic and external dimensions of the system itself.

• If economic caution prevails, we may observe a gradual rationalization of regional behavior.
• If the imperative of demonstrating cohesion dominates, risk-taking may temporarily increase before equilibrium stabilizes.

In either case, the Middle East is unlikely to face a strategic vacuum. Instead, the region will enter a phase of risk redistribution, in which domestic, economic, and regional dynamics interact to produce a balance that is both more complex and less predictable.
