Iran Strikes Back: How ‘Horizontal Escalation’ Threatens to Widen the Gulf War

A Widening Conflict: How Iran’s Response to ‘Operation Epic Fury’ Shifts the Calculus

The initial hours of ‘Operation Epic Fury’ – the joint U.S.-Israeli military offensive against Iran launched on February 28, 2026 – showcased the precision of modern warfare. Strikes targeted Iran’s Supreme Leader, Ayatollah Ali Khamenei, alongside senior Islamic Revolutionary Guard Corps (IRGC) commanders and intelligence officials, intended as a decisive blow to cripple Tehran’s command structure. Although, this hope for a limited response was quickly dashed. Within hours, Iran launched hundreds of ballistic missiles and drones, not only at Israel but also across the Gulf region, signaling a strategy of escalation that extends far beyond direct retaliation.

The Iranian response immediately broadened the scope of the conflict, with air raid sirens sounding in major Israeli cities like Tel Aviv and Haifa. Missiles were intercepted over Doha and Abu Dhabi, and personnel at Al Udeid Air Base in Qatar – the forward headquarters of U.S. Central Command – sought shelter. U.S. Bases in the United Arab Emirates (Al Dhafra) and Kuwait (Ali Al Salem), as well as Prince Sultan Air Base in Saudi Arabia, also reported incoming threats. Naval forces near the U.S. Fifth Fleet headquarters in Bahrain were placed on high alert. This rapid and widespread retaliation demonstrates a deliberate strategy to multiply arenas of risk, a tactic that has historically altered the calculations of more powerful adversaries.

Beyond Retaliation: A Strategy of Horizontal Escalation

The impact of Iran’s strikes extends beyond military targets. Civilian casualties have been reported, airports have been shuttered, shipping and oil exports are threatened, and the region’s image of stability has been tarnished. An iconic hotel in Dubai sustained fire damage after being hit by debris from an intercepted drone, and Kuwaiti authorities reported damage near civilian airport facilities. The disruption to maritime traffic near the Strait of Hormuz has already prompted a spike in shipping insurance premiums, highlighting the potential for significant economic consequences. Oil futures jumped sharply as traders factored in the risk of sustained disruption to one of the world’s most critical energy chokepoints. The National Interest details the initial assessment of the operation and its immediate aftermath.

This isn’t simply scattered retaliation; it’s a calculated strategy of “horizontal escalation.” This approach, as outlined in the analysis of past conflicts, aims to transform the stakes of a conflict by widening its scope and extending its duration. It allows a weaker combatant to alter the calculus of a more powerful foe. The examples of Vietnam and Serbia are particularly relevant. In both cases, the United States faced adversaries who responded to overwhelming airpower with horizontal escalation, ultimately leading to American defeat in Vietnam and frustrating U.S. War aims and contributing to ethnic cleansing in the former Yugoslavia. Decapitation strikes, in particular, create a powerful incentive for this type of response: when a regime survives the loss of its leader, it must demonstrate resilience by expanding the conflict.

Multiplication of Exposure: Targeting Allies and Infrastructure

Iran’s strategy unfolds in a recognizable pattern. First, it demonstrated resilience by launching a large-scale retaliation within hours of losing key leadership figures, signaling continuity of command and operational capacity. Second, it widened the conflict beyond Iranian territory, effecting what scholars term “multiplication of exposure.” Targets were struck or threatened in at least nine countries, most of which host U.S. Forces: Azerbaijan, Bahrain, Greece, Iraq, Jordan, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates. The message was clear: countries hosting American forces would face severe consequences, and the conflict initiated by Israel and the United States would spread.

This expansion of the conflict has had tangible consequences. The closure of airports, damage to commercial property, and the disruption of energy and insurance markets have forced Gulf leaders to reassure foreign investors and tourists. The war has moved beyond the battlefield and into boardrooms and parliamentary chambers. In the United States, the widening scope of the war has already raised concerns among members of Congress. Numerous actors are now involved, each pursuing distinct interests, and capable of altering the trajectory of escalation beyond Washington’s control.

The Political Dimension: Shaping Regional Narratives

Iran’s actions are not solely about inflicting damage; they are fundamentally political. Tehran aims to puncture the perception of invulnerability surrounding Gulf states like Dubai and Doha, which market themselves as secure hubs for finance, tourism, and logistics. Disruptions at Dubai International Airport, one of the world’s busiest, carry a significant reputational cost. The reported deaths of foreign workers in the United Arab Emirates underscore the vulnerability of civilians.

Iran is raising the political cost for Gulf countries of hosting U.S. Forces. By striking near American bases, Tehran signals that alignment with Washington entails exposure to attack, forcing Gulf leaders to balance alliance commitments against domestic and economic stability. Iran is also actively shaping a narrative about the regional order, portraying its actions as resistance to a U.S.-Israeli campaign aimed at regional dominance, seeking to drive a wedge between Gulf leaders and their publics.

Echoes of Past Conflicts: Vietnam and Kosovo

The current situation echoes past conflicts where assumptions about the decisive power of airpower proved flawed. The U.S. War in Vietnam, despite overwhelming air superiority, ultimately failed to achieve its objectives. By 1967, the United States had dropped more tonnage on North Vietnam than it had used in World War II, yet Hanoi responded by widening the conflict into South Vietnam’s cities, transforming a military contest into a nationwide political upheaval. The United States may have won every battle, but ultimately lost the war.

Similarly, Operation Allied Force in Kosovo in 1999, initially envisioned as a swift campaign of precision strikes, led to a mass exodus of Kosovar Albanians and ultimately required the mobilization of nearly 40,000 ground troops to achieve its objectives. Both Vietnam and Kosovo demonstrate that airpower, while disruptive, does not automatically translate into political outcomes. Adversaries can and do respond by widening the conflict’s scope or prolonging it through horizontal escalation.

What Happens Next: A Strategic Fork in the Road

The United States now faces a critical choice. One path involves doubling down – ramping up the airpower campaign to suppress Iranian launch capabilities and establish aerial control. This approach, akin to the prolonged aerial containment of Iraq in the 1990s, risks escalating the conflict into a long-term commitment with uncertain outcomes. The other path is to declare objectives “met” and stand down its forces, accepting short-term political criticism in exchange for limiting the potential for further escalation.

As The Jerusalem Post reports, support for the new leadership in Iran is consolidating, suggesting that any gestures of apology to Gulf neighbors may be tactical rather than indicative of a shift in strategy. The initial strike may have solved a tactical problem, but it has created a strategic one. Given these realities, a limited loss now may be preferable to compounding losses later. The decisive phase of this war began not with the first strike, but with the regional crisis that followed – air defenses activated, airports suspended, markets jolted, and alliance politics strained. Whether this conflict remains contained or becomes a prolonged setback for the United States will depend on whether Washington recognizes Iran’s unfolding strategy and responds with one of equal clarity.
