The Gaza war has accelerated a structural transformation in Iran’s regional strategy. Rather than relying on loosely connected militant allies, Tehran is increasingly building a coordinated system of proxy actors capable of generating simultaneous crises across multiple theatres. Through a combination of missile proliferation, drone networks and maritime disruption, Iran has developed a model of distributed warfare that allows it to project power while avoiding direct confrontation with stronger military powers. If this trajectory continues, the Middle East may become the first region where proxy conflict evolves into a permanent architecture of strategic competition.

The war in Gaza was not merely another episode in the region’s cycle of crises. Rather, it acted as a catalyst for a structural transformation of Iran’s regional strategy. Developments since 2023 suggest that Tehran is gradually moving away from a fragmented model of supporting allied militant groups toward a more coordinated system of managed conflicts. What is emerging is an institutionalised architecture of proxy warfare that allows Iran to project power across the region while avoiding direct military confrontation with technologically superior adversaries.

The central instrument of this strategy remains a network of allied non-state actors commonly referred to as the “Axis of Resistance.” Yet the structure of this network has evolved significantly. Whereas organisations such as Hezbollah, Iraqi Shiite militias, or the Yemeni Houthis once operated largely within the confines of local conflicts, they are increasingly functioning as elements of a broader operational system coordinated through structures of the Islamic Revolutionary Guard Corps (IRGC), particularly its external operations branch, the Quds Force.

This coordination manifests itself in several dimensions. First, there has been a growing standardisation of military capabilities. The proliferation of missile systems and unmanned aerial technologies has significantly expanded the operational reach of proxy groups. Second, intelligence sharing and operational coordination among various allied organisations appear to have intensified. Third, a more resilient logistical infrastructure has emerged, relying on supply corridors running through Iraq, Syria and Lebanon and effectively linking Iran to the Eastern Mediterranean.

One of the clearest examples of this transformation is Hezbollah. According to various estimates, the organisation possesses an arsenal ranging between 120,000 and 200,000 rockets and missile systems. These include short-range tactical rockets as well as more advanced Iranian-supplied platforms capable of striking targets at distances of up to 200–300 kilometres. Such capabilities position Hezbollah as a central component of Iran’s deterrence posture against Israel and provide the capacity to threaten a significant portion of Israel’s critical infrastructure in the event of large-scale escalation.

At the same time, the use of unmanned systems has expanded rapidly. Iran has invested heavily in the development and dissemination of strike drones, including platforms from the Shahed family. These systems are not only deployed by Iran itself but are increasingly transferred to allied groups across the region. The diffusion of drone technologies and components has enabled the emergence of a distributed network of unmanned strike capabilities, significantly enhancing the operational potential of proxy actors while keeping the cost of operations relatively low.

Maritime routes have become another critical arena within this strategy. Houthi attacks on commercial shipping near the Bab el-Mandeb Strait have demonstrated that proxy groups can be used not only in land conflicts but also as instruments of geo-economic pressure. Since late 2023, the Houthis have conducted more than one hundred attacks against commercial vessels and naval assets using anti-ship missiles, unmanned aerial vehicles, and maritime drones. These actions have placed one of the world’s key maritime trade corridors under persistent threat, affecting a route through which a substantial share of global shipping between Europe and Asia passes.

As a result, a new model of distributed pressure is emerging, in which multiple actors are capable of generating crises simultaneously across several geographic theatres. This development weakens the effectiveness of traditional deterrence strategies based on direct state-to-state confrontation. Instead of a single front, a network of interconnected conflict zones is created, each of which can be activated depending on the political context.

The response of the United States and its allies to this strategy has gradually taken the form of coalition-based deterrence. To protect maritime trade routes in the Red Sea, an international naval force has been established with the aim of safeguarding shipping and intercepting missile and drone threats. In parallel, the United States has carried out limited strikes against Houthi targets in Yemen as well as against infrastructure used by Iran-backed militias in Iraq and Syria.

Israel, for its part, continues to pursue a strategy of active deterrence. This includes regular strikes against Iranian military infrastructure in Syria, operations targeting weapons transfer networks, and preparations for potential escalation on the northern front. The primary objective of this approach is to prevent the emergence of a fully developed missile and drone front along Israel’s borders.

For Tehran, however, proxy warfare remains a rational response to the structural imbalance of power in the region. Iran lacks the resources to sustain a direct symmetrical confrontation with major military powers. Instead, it has opted to develop a network of asymmetric instruments capable of gradually eroding existing regional deterrence structures.

Over the longer term, this system is likely to become more deeply institutionalised. Advances in unmanned platforms, the continued development of missile technologies, and deeper coordination among proxy groups are expected to strengthen the capacity for distributed warfare. As a result, the Middle East is increasingly evolving into a space of indirect conflict in which the central actors are not only states but also complex networks of armed organisations.

Iran is thus gradually constructing what may become the first institutionalised system of proxy conflict in the modern history of the Middle East. Through a network of allied armed actors, a distributed missile and drone infrastructure, and the ability to activate multiple escalation zones, Tehran has acquired the capacity to project power far beyond its borders without engaging in direct confrontation with stronger military powers.

If this trajectory continues, the Middle East could become the first region where proxy conflicts are fully institutionalised as a permanent mechanism of strategic competition. In such a scenario, the main line of confrontation will run not simply between states but between transnational networks of armed actors and the coalitions of states seeking to contain them. It is this transformation — rather than any single regional crisis — that may ultimately shape the security architecture of the Middle East in the decades ahead.
