Wars in the Middle East are no longer fought exclusively through regular armies and conventional frontlines, nor are power balances measured solely by the size of missile arsenals or the number of combat aircraft. Conflict in recent years has shifted to a more complex level in which geography itself has become part of the toolkit of confrontation, after having long served merely as a stage upon which military operations unfolded. In this context, maritime straits and critical sea lanes have emerged as strategic anchor points that govern the flow of energy and trade and whose disruption can reshape the map of influence in the region and the global economy at large. 

Iran grasped early on that the Strait of Hormuz and Bab al-Mandab are not just logistical arteries in the structure of the international economy, but true keys in the balance of power. Whoever can disrupt or threaten these arteries holds leverage that extends beyond direct military confrontation and into the heart of financial markets and global supply chains. As the U.S.–Israeli confrontation with Iran has expanded, the straits have been drawn ever more tightly into Tehran’s toolbox of deterrence and bargaining, to the point that any discussion of the future trajectory of the conflict now intimately interlinks with the question of maritime security.  

Against this backdrop, this assessment offers an in-depth analytical reading of how maritime geography – and chokepoints in particular – has been reconfigured within Iran’s regional strategy, and how this reconfiguration is reshaping the strategic geography of conflict in the Middle East. 

Iran’s Evolving Influence: From Power Projection to Strategic Reshaping  

Iran’s regional strategy over the past decades has rested on a logic that diverges from the classical model of direct military control. At its core is the exploitation of the fragility across several Arab contexts to build layered influence through local non-state actors ideologically, politically, and militarily aligned with Tehran. In Lebanon, this influence is embodied in Hezbollah; in Iraq, in a broad spectrum of armed factions; in Syria, through a military and security presence enmeshed with the structure of the former regime; and in Yemen, in the Houthis. 

This pattern of expansion does not seek to occupy territory in the traditional sense, it aims to construct a cross-border, flexible, and adaptive network of influence whose tempo can be managed in line with escalation/de-escalation dynamics. In this way, these arenas become multi-purpose pressure platforms: activated in times of crisis and partially frozen during phases of negotiation, without Iran having to bear the full cost of direct engagement in each theater. More importantly, this network extends beyond the strictly geographical dimension to reshape the strategic environment itself, such that any confrontation with Iran becomes a confrontation with an extended system of proxies and entities, not a simple clash with a single state confined within its borders. 

In this sense, Iran is not merely filling a security or political vacuum left by international actors or weak regimes. It is redefining that vacuum and turning it into part of a deterrent belt encircling its adversaries, stretching from the eastern Mediterranean to the southern entrance of the Red Sea. Once these fragile environments are woven together with the surrounding maritime spaces, Tehran can move from engineering influence on land to engineering maritime influence, turning chokepoints into the natural extension of its land-based network of influence. 

The Weaponization of Chokepoints  

In classical warfare, the objective was to gain permanent control of sea lanes to ensure secure use by one side or to deny access to the other. In contemporary hybrid conflicts, however, a new logic has taken root: the ability to threaten or partially disrupt a waterway can be more effective – and less costly – than fully controlling it. Simply generating uncertainty about the safety of transit is enough to increase oil prices, raise insurance premiums, and force companies to recalculate their routes and risk exposure. 

Within this framework, Iran has harnessed its geographic position in the Strait of Hormuz, along with its naval and missile capabilities, to dial the level of threat up without crossing the threshold of total closure that might trigger a massive international response. Attacks on commercial vessels, the reported deployment of naval mines, and political statements alluding to Tehran’s closure of the Strait are all instruments in a campaign of calibrated disruption that does not completely sever this artery of energy, but makes the world acutely aware of its vulnerability and the ease with which it could be cut. 

In this sense, the Strait of Hormuz is no longer merely a channel for millions of barrels of oil per day. It has become an integral component of Iran’s deterrence arsenal. This card can be played more aggressively or more cautiously depending on the trajectory of negotiations over other pressing issues, from the nuclear file and economic sanctions to regional security arrangements and the scope of Iran’s role in emerging spheres of influence.  

Yemen and the Red Sea: From the Periphery of Conflict to Its Core 

If the Strait of Hormuz represents Iran’s direct lever in the Gulf, Bab al-Mandab functions as an indirect extension of its influence through Yemen. The most striking development in this regard is the transformation of the Houthi movement from a local actor in an internal conflict with the Yemeni government and coalition states into a pivotal element in a broader Iranian architecture designed to weaponize maritime routes as part of its deterrence posture. 

Yemen’s location on the eastern shore of the Red Sea, and its direct proximity to Bab al-Mandab, grants the Houthis a unique capacity to affect one of the world’s most important maritime passages. As Houthi missile and naval capabilities have expanded and their attacks on commercial and military vessels have grown more frequent, the cost of transit through this corridor has increased. At various points, shipping companies have been compelled to reroute via longer, more expensive paths, highlighting the vulnerability of this vital maritime chokepoint.  

This shift reflects the Red Sea’s growing strategic significance as an increasingly contested maritime theatre shaped by regional conflict dynamics. It also underscores Iran’s success in constructing dual strategic depth: a land-based political depth extending through its proxies and units spread from Iraq to Lebanon, and a maritime depth embodied in its capacity to influence both the Strait of Hormuz and Bab al-Mandab.  

In this environment, the Houthis have demonstrated their role as a regional actor capable of impacting equations that far exceed the confines of Yemen, gaining additional bargaining weight while providing Iran with a lever of maritime pressure at the junction of global shipping routes. 

Encircling the Gulf and Redefining the Threat 

As simultaneous threats escalate in the Gulf and the Red Sea, an analytically significant scenario comes into focus: the strategic encirclement of the Gulf from the south. While the Strait of Hormuz constitutes the eastern gateway for Gulf energy exports, Bab al-Mandab serves as a key exit point for those exports toward European markets via the Suez Canal. Iran’s ability to influence the former directly and the latter indirectly translates into a growing capacity to pressure the terminals and outlets of Gulf energy. 

This development does more than simply add another front to Gulf security calculations. It fundamentally redefines the nature of the threat. Threats are no longer primarily conventional in nature, nor do they emanate from a single direction, making them harder to contain by reinforcing defenses on a single front. They now take the form of multi-directional risks in which maritime and land dimensions intersect, states and non-state actors intermingle, and critical chokepoints themselves become part of the contested battle space. 

As a consequence, Gulf states’ strategies must shift from containing a defined threat to defending multiple corridors and domains simultaneously. This transition carries far-reaching implications for their military doctrine, force posture, and defense spending priorities. It also highlights the limits of a security model heavily premised on external protection: recent experience has demonstrated that even advanced international capabilities cannot guarantee the safety of every vessel in the Red Sea or the Gulf, nor can they neutralize every threat posed by non-state actors employing guerrilla-style tactics at sea and asymmetric attack methods. 

Asymmetric Deterrence and Multi-Theater Pressure 

A defining feature of Iran’s evolving strategy is its shift away from attempting to match its adversaries in conventional capabilities and toward adopting an asymmetric deterrence model grounded in the use of relatively low-cost tools with high strategic effect. This model relies on generating an interlinked web of pressure points spread across the region, such that activation of pressure in one theater reduces pressure on another or improves Iran’s bargaining position on issues seemingly detached from the immediate crisis. 

Within this framework, maritime chokepoints and sea lanes become central nodes in the deterrence network. Threatening navigation through the Strait of Hormuz raises the cost of economic sanctions; pressure at Bab al-Mandab alters the calculus of major powers considering direct military intervention; and mobilizing proxies across different fronts disperses the attention of Iran’s adversaries and forces them to spread their forces and assets across a wide and shifting geographic space. In this way, a deterrent architecture emerges that is based less on the display conventional military superiority and more on the management of complexity. 

This logic reflects a sophisticated understanding of how power has evolved in the contemporary era, where military, economic, informational, and legal dimensions intertwine, and wars can no longer be decided by a single missile strike or air campaign. Power is increasingly measured by the ability to disrupt supply chains, erode market confidence, and create an environment of uncertainty that drains the adversaries’ resources and nerves without necessitating all-out war. At the heart of this lies the role of maritime chokepoints as points of global vulnerability where even limited disruption can reverberate through the entire international economic system.

Toward a New Framework of Arab Maritime Security 

In the face of this shifting landscape, it has become evident that traditional approaches to maritime security in the Arab world are no longer adequate. Treating Gulf security and Red Sea security as separate files, and viewing each chokepoint in isolation, no longer aligns with the nature of the interlinked threat that connects the Strait of Hormuz, Bab al-Mandab, and the Suez Canal into a single chain. 

An effective response requires developing a holistic concept of Arab maritime security grounded in several key pillars. The first is recognizing that the security of chokepoints is not merely a military matter, but a sovereign, economic, and strategic question that bears directly on the role of Arab states in the international system and their ability to safeguard their vital interests. The second is building robust frameworks for naval and intelligence cooperation among states bordering these waterways, encompassing joint early warning and surveillance mechanisms, systematic information-sharing, and coordinated planning to protect sea lanes under conditions of threat. 

A third pillar lies in recasting partnerships with global powers to balance the benefits of advanced international capabilities with the preservation of Arab strategic autonomy and the development of indigenous capacity. Maritime security cannot remain wholly dependent on external arrangements, nor can it be reduced to the presence of foreign fleets in regional waters. It must become part of a broader project of Arab strategic self-reliance, linking the protection of chokepoints to sustainable economic development and the preservation of sovereignty. 

Conclusion

Iran’s current use of straits and maritime corridors does not primarily seek a conventional military victory, it aims to reshape the rules of the game. By acquiring the ability to threaten the arteries of global energy and trade, and by constructing a network of influence stretching from the shores of the Gulf to the banks of the Red Sea, Tehran is working to entrench a strategic equation in which any attempt to isolate or strike it carries a cost not only for its adversaries, but for the global economy at large. 

Yet this strategy, despite the leverage it affords Iran, carries profound risks for the region and the wider world. Once chokepoints are transformed into instruments of conflict, the international economic order becomes more vulnerable to recurrent shocks, and local crises can trigger global tremors that affect energy prices, trade flows, and supply chains. Each round of escalation reinforces the realization that the presumed neutrality of sea lanes can no longer be taken for granted: geography has therefore ceased to be a fixed frame for conflict and has become a weapon in its own right.
