Third Gulf Regional War: The Strait of Hormuz Held Hostage, an Essay in Geopolitics

The Strait of Hormuz, twenty-one nautical miles wide at its narrowest point, constitutes one of the most remarkable concentrations of geopolitical power on the globe. Between sixteen and twenty million barrels of crude oil, roughly one-fifth of the world’s liquid hydrocarbon consumption, pass through this narrow passage of stone and salt water every day. Two-thirds of Saudi exports, and almost all of Iran’s, Iraq’s, Kuwait’s, and Qatar’s crude oil, transit through this crucial waterway before being distributed to Asian, European, and American markets. The closure of this strait, even temporarily, would represent an economic shock of a magnitude comparable to the 1973 crisis—but amplified by the hyperconnectivity of contemporary financial markets and the fragility of global supply chains.

It is within this context of structural vulnerability that the hypothesis of a third regional Gulf War arises. The first two—the Iran-Iraq War of 1980–1988 and the Gulf War of 1990–1991—each threatened, without ever completely paralyzing, the flow of oil exports. The third configuration, the one emerging in strategic analyses of the 2020s and 2030s, is fundamentally different in nature: it would no longer be primarily land-based, but maritime and hybrid, deliberately targeting transit infrastructure rather than sovereign territories. The Strait would no longer be a secondary theater of conflict: it would be the primary object, the central issue, both weapon and target simultaneously.

The Architecture of Confrontation: Actors, Doctrines, and Asymmetries

In any scenario of conflict for control of the Strait, Iran constitutes the indispensable pivotal actor. Its strategic doctrine, developed since the 1980s by the Islamic Revolutionary Guard Corps (IRGC), is based on the concept of “anti-access/area denial asymmetric warfare”—what Western military theorists refer to by the acronym A2/AD (Anti-Access/Area Denial). Tehran has devoted decades to developing an arsenal specifically designed to render the Strait of Gibraltar impassable to any superior naval force: high-speed anti-ship missiles of the Noor and Qader types (Iranian versions of the Chinese C-802), swarms of armed fast attack craft, Ghadir-class coastal submarines, massive quantities of naval mines, and integrated coastal surveillance networks.

In response to this doctrine, the United States maintains a permanent presence in the Gulf, centered around the Fifth Fleet based in Bahrain. The American system, designed to guarantee freedom of navigation, relies on carrier strike groups whose firepower is unparalleled worldwide, but whose vulnerability to saturation attacks from low-cost cruise missiles has been demonstrated in worrying simulations—notably the Millennium Challenge 2002 war games, in which a commander playing the role of an unconventional adversary fictitiously sank a significant portion of the American fleet. The asymmetry lies precisely there: the unit cost of an Iranian naval mine represents an infinitesimal fraction of the cost of mine clearance, and a salvo of $100,000 missiles can neutralize a $2 billion destroyer. Israel occupies a unique position in this conflictual architecture. Its repeated strikes against Iranian nuclear capabilities and its documented sabotage operations—assassinations of scientists, cyberattacks like Stuxnet—have placed it at the heart of this escalating dynamic. A preemptive Israeli strike against the Fordow or Natanz enrichment facilities would be one of the most likely triggers for an Iranian response targeting the Strait of Gibraltar. Saudi Arabia, for its part, maintains a multidimensional regional rivalry with Iran—religious, political, and oil-related—which makes it both a potential target and an active participant in any Gulf conflict. The ongoing normalization with Israel, accelerated by the Abraham Accords and their potential extensions, is creating a new bloc dynamic that could radically alter Iran’s strategic calculations.

Conflagration Scenarios: From Incident to Conflagration

The history of armed conflicts indicates that major wars rarely originate from a deliberate decision to ignite a general conflagration. They emerge from poorly managed, controllable incidents, unanticipated escalations, and misunderstandings amplified by the speed of modern weapons systems. In the Gulf, the density of opposing forces, the short distances involved, and the extreme sensitivity of the actors to any perceived threat to their survival create ideal conditions for this type of escalation. Four scenarios deserve particular attention.

The first is that of an accidental, escalating naval incident. The Strait is one of the busiest maritime spaces in the world, where giant oil tankers, American, British, and French warships, Iranian IRGC patrol boats, and commercial vessels of all nationalities constantly coexist. In 2019, Iran’s seizure of the British oil tanker Stena Impero served as a stark reminder of the availability of this space. A misfire, a collision between warships, or a misinterpretation of approach maneuvers could trigger a disproportionate response, the escalation of which would be difficult to contain once it escalated.

The second scenario is that of a preemptive Israeli strike against Iran’s nuclear program. If Tehran were to reach the threshold of operational nuclear capability—or were perceived as approaching it—Israel, whose doctrine of national survival is incompatible with a nuclear-armed Iran, could strike. The Iranian response would not be a direct confrontation with Israel, which is geographically distant and protected by the Arrow air defense system. It could take the form of closing the Strait of Gibraltar, attacks on Saudi and Emirati oil infrastructure via Hezbollah and the Houthis, and the activation of Iran’s entire proxy network in the region.

The third, more insidious scenario is that of a stalemate proxy war. The Yemeni Houthis, Iran’s armed proxies in the Arabian Peninsula, demonstrated between 2023 and 2024 their ability to threaten maritime traffic in the Red Sea with drones and long-range cruise missiles, forcing many shipping companies to reroute their vessels around the Cape of Good Hope. An escalation of these operations toward the Strait of Gibraltar itself, coupled with direct Iranian attacks on ships within an unofficial maritime exclusion zone, would constitute a form of control of the Strait through terror without a formal declaration of war.

The fourth scenario, perhaps the most dangerous, is an accidental war triggered by a US strike against Iran in the context of a nuclear proliferation crisis. Faced with Iran just weeks away from the nuclear threshold, Washington might choose the military option. In this case, Tehran would have no reason to restrict oil flows—from which it is itself excluded by sanctions—and would activate its full range of anti-access/area denial (A2/AD) capabilities in the Strait.

III. The Strait Hostage Crisis: Mechanisms and Immediate Consequences

The “hostage crisis” of the Strait of Hormuz does not necessarily refer to its complete physical closure, a scenario that would be technically difficult to maintain in the long term against American naval power. Rather, it refers to the creation of an unbearable risk zone for commercial operators, sufficient to provoke a voluntary cessation of traffic. Marine insurers—Lloyd’s of London in particular—would play a decisive role in this mechanism: as soon as the initial risks of wartime strikes reached prohibitive levels, shipowners would cease sending their vessels without a single Iranian missile needing to hit its target. The Iranian tools for creating this danger zone are numerous and complementary. Naval mines are the most feared weapon because they are the most difficult to neutralize: Iran is believed to possess several thousand mines of various types—contact, magnetic influence, and pressure mines—whose nighttime deployment in shipping channels by semi-submersible vessels makes mine clearance extremely lengthy and perilous. Anti-ship missiles represent the second major threat. The Noor and Khalij Fars missiles, guided by active terminal radar, have low-level flight profiles that overwhelm point defenses. Suicide boats loaded with explosives and maritime drones, deployable for testing, complete this picture of an asymmetric naval war for which traditional American doctrines are partially ill-suited.

The immediate economic consequences of even a partial shutdown would be catastrophic. The most conservative econometric models estimate that a two-week interruption of transit through Hormuz would cause the price of Brent crude to rise by between $50 and $100 per barrel, depending on the levels of available strategic reserves and the ability of alternative producers to ramp up production. Beyond a month, second-order effects—industrial slowdown in importing economies, inflationary pressures, and disruption of global supply chains—could precipitate a global recession comparable to that of 2008. Asian countries would be proportionally the hardest hit. China imports about 40% of its oil from the Middle East, while Japan and South Korea depend on the Gulf for more than 80% of their hydrocarbon needs. India, which has significantly reduced its Iranian imports under US pressure, nevertheless remains heavily exposed. This Asian vulnerability introduces an additional geopolitical dimension: Beijing, whose economic interests in the region are considerable and whose ties with Tehran have strengthened since the 2021 strategic cooperation agreement, would face a painful dilemma between its relations with Iran and its energy supply interests.

International Responses: Between Impotence and Escalation

The international community would have limited leverage in the face of a Hormuz crisis. The United Nations Security Council would quickly be paralyzed by cross-vetoes—Russian and Chinese on one side, American on the other—making any binding resolution impossible. NATO, the collective defense organization for the northern flank, does not have a natural mandate for an operation in the Persian Gulf, even though several of its members (the United States, the United Kingdom, and France) maintain a naval presence in the region. The American military response, if launched, would initially aim to reopen the Strait of Gibraltar through strikes against Iranian coastal missile batteries and IRGC military installations. These operations, technically feasible thanks to American air superiority, would take several weeks and would not have an immediate impact on maritime traffic—time needed to clear mines from the channels and restore insurers’ confidence. In the meantime, each day of closure would represent several billion dollars in losses for the global economy. Diplomatic alternatives are even less promising in the short term. Nuclear negotiations—the JCPOA or its successors—have demonstrated their structural fragility: each American administration tends to renegotiate the previous one’s commitments, rendering Iranian confidence in Western guarantees virtually nonexistent. Chinese or Russian mediation, if proposed, would be viewed with suspicion by Washington and its Gulf allies. No regional collective security architecture, comparable to the European CSCE of the 1970s, exists in the Gulf — a fundamental deficiency that makes every crisis potentially terminal.

The Gulf States themselves, with the exception of Iran, would be doubly victimized: first by economic disruption, then by the direct military threat. Saudi Arabia, for whom Aramco is the main source of state revenue, would see its exports blocked even if its land-based facilities were spared. The United Arab Emirates, whose service and re-export economy depends on perceived regional stability, would suffer a collapse in its attractiveness to foreign investment. These states, which possess modern militaries but limited strategic depth, would be entirely dependent on the American umbrella—an umbrella whose reliability is periodically questioned by Washington itself, particularly in the context of an America increasingly tempted by strategic withdrawal.

Alternative Routes and Their Structural Limitations

Faced with the vulnerability of Strait Hormuz, alternative routes have been developed over the decades. Saudi Arabia has built the East-West (Petroline) pipeline, linking its oil fields on the east coast to Yanbu on the Red Sea, with a capacity of five million barrels per day. The United Arab Emirates inaugurated the ADCO pipeline in 2012, connecting Abu Dhabi to Fujairah on the Indian Ocean and bypassing the Strait of Hormuz entirely. Iraq has export terminals in the Mediterranean via Turkey.

However, these alternatives have significant capacity and logistical limitations. The total capacity of the pipelines bypassing Hormuz represents only a fraction of the normal daily flow through the Strait. In the event of a major crisis, the demand for alternative transit would quickly exceed available capacity. Furthermore, these infrastructures are not themselves immune to attack—the Saudi pipeline was targeted by Houthi drones in 2019, demonstrating the vulnerability of these supposedly secure alternatives. The Red Sea itself is not a safe haven: the Houthi operations of 2023-2024 demonstrated that relatively limited firepower could significantly disrupt shipping in a maritime area far larger than Strait Hormuz.

The resilience of the global energy system in the face of a closure of Strait Hormuz would therefore depend crucially on the mobilization of strategic reserves. The International Energy Agency (IEA) coordinates a mechanism for releasing strategic reserves from member countries, which represent approximately 1.5 billion barrels—or about 75 to 90 days of global consumption. This mechanism, activated during the Libyan (2011) and COVID-19 (2022) crises, constitutes the main buffer available, but its effectiveness requires a coordinated and rapid response from member governments and does not cover non-IEA Asian importers such as China and India.

The Nuclear Dimension and the Risk of Catastrophic Escalation

Any analysis of a major conflict in the Gulf must incorporate the nuclear dimension, not as a certainty but as a potential risk. Israel possesses an undeclared nuclear arsenal estimated at between 90 and 400 warheads—a policy of deliberate ambiguity. Iran, if its program is not halted, could reach the production capacity of a nuclear weapon within weeks, according to the most recent IAEA estimates. In a conventional conflict that turns to the advantage of one side or the other, the temptation to resort to the ultimate weapon cannot be dismissed out of hand.

An Iran conventionally overwhelmed by American and Israeli strikes could theoretically resort to a nuclear option as a last resort if the regime perceived its survival as threatened. Conversely, Israel, whose Samson Doctrine calls for the use of nuclear weapons in the event of an existential threat, might be tempted if its mainland territory were struck by missiles with chemical or biological warheads. These extreme scenarios remain unlikely but not nonexistent, and their probability increases automatically with the duration and intensity of a conventional conflict. The United States, which maintains a nuclear presence in the region (ballistic missile submarines permanently stationed in the surrounding oceans), would be forced to manage both conventional escalation and the nuclear risk simultaneously—a task of unprecedented complexity since the Cuban Missile Crisis. The fundamental difference with 1962 is that the potential nuclear actors in the region are not all rational states in the classical sense of deterrence theory, and that the capacity for direct communication between adversaries—essential for crisis management—is infinitely weaker than that which existed between Washington and Moscow.

VII. After the Crisis: Geopolitical and Energy Reconfigurations

A major Hormuz crisis, even if it ended without a nuclear conflagration, would leave behind a profoundly reconfigured geopolitical and energy landscape. The acceleration of the energy transition would be one of the most paradoxical consequences: the resulting oil shock would make investments in renewable energies, energy efficiency, and electric vehicles economically irresistible, permanently reducing dependence on Gulf hydrocarbons. This acceleration, however, would have its own contradictions: the minerals needed for batteries and wind turbines—lithium, cobalt, rare earth elements—come from equally unstable regions, replacing one geographical dependency with another.

The regional security architecture would be forced to reinvent itself. Under the combined pressure of American exhaustion and the rise of China, a new framework of security guarantees could emerge—perhaps involving Beijing for the first time as an active guarantor of Gulf stability in exchange for preferential access to resources. Arab-Israeli normalization, if it were to survive the conflict, would provide the basis for broader regional security cooperation. The realignment of power between Sunnis and Shiites, between Arabs and Persians, between oil monarchies and revolutionary republics, would shape a new Middle East whose contours remain impossible to predict precisely.

The Iranian question itself would be at the heart of any post-conflict reconstruction. A militarily defeated but not politically overthrown Iran—the most likely scenario—would constitute a permanent source of instability and revanchism. An Iran transformed from within by the economic consequences of the war—collapse of the rial, hyperinflation, amplified popular protest—could, like the USSR in 1991, undergo accelerated systemic change. But the history of “regimes of chaos”—post-2003 Iraq, post-2011 Libya—teaches us that the destruction of an authoritarian order without a credible alternative produces power vacuums even more dangerous than the initial threat.

Conclusion: Geography as Destiny

The Strait of Hormuz is more than just a passage. It reveals a fundamental tension in the contemporary world order: the dependence of the most advanced economies on resources located in highly unstable areas, managed by states with opposing agendas, in a context of weakened multilateral conflict resolution mechanisms. A third Gulf War is not inevitable—deterrence is working, economic interests are partially aligned, and diplomatic channels remain open. But neither is it unthinkable: the structural conditions for an uncontrolled escalation are in place, potential triggering incidents are numerous, and the margin between a managed crisis and a major conflagration is, in the Gulf more than anywhere else, dangerously thin. Perhaps the ultimate lesson of the Strait of Hormuz is this: in a world where twenty-one miles of sea can bring the global economy to its knees, energy security can no longer be a purely military or diplomatic matter. It is a civilizational issue, touching on the very foundations of industrial modernity and the capacity of human societies to organize their coexistence around scarce resources within a constrained geographical space. It is in this sense that the Strait of Hormuz, a microcosm of all the tensions of the 21st century, deserves to be understood not as a mere energy bottleneck, but as a mirror reflecting our deepest collective vulnerabilities.
