CASE STUDY

Published: March 8, 2026  |  Conflict Timeline: February 28 – Present

Executive Summary

On February 28, 2026, the United States and Israel launched coordinated strikes on Iran under Operations Epic Fury and Roaring Lion. The campaign killed Supreme Leader Ayatollah Ali Khamenei, dozens of senior officials, and struck military, nuclear, and government infrastructure across the country. Iran responded with an unprecedented barrage of missiles and drones directed at all six Gulf Cooperation Council (GCC) states — a first in history — targeting civilian and energy infrastructure including airports, LNG facilities, and oil refineries. As of March 8, the conflict shows no signs of imminent resolution, with Trump threatening further escalation and Iran vowing continued resistance.

This case study examines the origins, key developments, political dynamics, economic impact, and potential pathways to resolution of the most significant regional conflict since the 2003 invasion of Iraq.

1. Background and Origins

1.1 Historical Context

The antagonism between the United States and the Islamic Republic of Iran is rooted in decades of contested history. A US- and UK-backed coup in 1953 deposed Prime Minister Mohammad Mosaddegh and entrenched the autocratic rule of the Shah, generating deep anti-Western resentment that contributed directly to the 1979 Islamic Revolution. Since that revolution, Iran has severed diplomatic ties with the US and Israel, engaged in proxy conflicts across the region through groups such as Hezbollah, Hamas, the Houthis, and Iraqi Shia militias, and pursued what Western governments characterised as a covert nuclear weapons programme.

The proximate trigger for the 2026 conflict was a convergence of factors: Iran’s violent suppression of domestic protests in late 2025, the collapse of renewed nuclear negotiations in early 2026, and a US intelligence assessment that Iran was approaching a nuclear breakout threshold. Following the deployment of two carrier strike groups to the Gulf in January and February 2026, the Trump administration — with strong Israeli backing — made the decision to strike.

KEY FACT

Operation Epic Fury was launched on February 28, 2026. It killed Supreme Leader Khamenei and is the first US military action to directly target an Iranian head of state.

2. Key Military and Political Developments

2.1 The Opening Strikes

The US–Israeli campaign targeted Iran’s nuclear infrastructure, IRGC command centres, air defence systems, and government facilities. The decapitation of Iran’s supreme leadership was unprecedented: Khamenei’s death removed the single most powerful figure in Iranian politics, creating an immediate vacuum in strategic decision-making and raising profound questions about the regime’s coherence and survival.

Over 1,300 Iranian civilians and military personnel have been killed as a result of the ongoing airstrikes, according to the Iranian Red Crescent Society. The strikes also caused significant collateral damage to civilian infrastructure, drawing international condemnation from Russia, China, and a number of EU member states.

2.2 Iranian Retaliation Strategy

Iran’s response has been defined by breadth rather than precision. For the first time, Tehran launched simultaneous attacks on all six GCC member states — Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE — using a combination of ballistic missiles, cruise missiles, and drone swarms. Targets included US military bases in Kuwait, Qatar, Bahrain, and Jordan; oil and gas infrastructure; airports; hotels; and diplomatic facilities, including the US Embassy compound in Riyadh.

Qatar — which had previously facilitated US–Iran ceasefire talks and nuclear negotiations — was struck despite its mediating role. Qatar’s LNG export terminals, representing approximately 20% of the global LNG market, were forced to suspend operations following Iranian drone attacks on key facilities. Oman, whose diplomats were actively mediating nuclear talks up to the day of the strikes, also suffered multiple attacks on its Duqm port complex.

ANALYSIS

Iran’s willingness to attack neutral mediators such as Qatar and Oman signals that the IRGC, now fully in operational command, is pursuing a maximalist deterrence strategy — punishing any state perceived as enabling US power projection regardless of diplomatic status.

2.3 The Command Fragmentation Problem

One of the most significant political developments of the conflict’s first week has been the visible split between Iran’s civilian presidency and the Islamic Revolutionary Guard Corps. President Pezeshkian issued an apology to Gulf states on March 7, pledging that Iran would halt attacks on neighbours unless strikes were first launched from their territory. Hours later, IRGC-aligned parliamentary speaker Mohammad Bagher Ghalibaf publicly reversed the commitment, stating Gulf nations hosting US military bases would remain targets.

The IRGC is now fully in operational command. Pezeshkian’s assurances carry no strategic weight within the Iranian security apparatus, and Gulf states have reacted with studied scepticism. A Gulf official speaking to NPR described Iran’s contrition as unverifiable, stating: ‘We will only believe it if we see it.’ The command fragmentation reduces the probability of a negotiated off-ramp, as any interlocutor faces the problem that civilian commitments cannot bind the IRGC.

2.4 Great Power Dimensions

The conflict has rapidly acquired great-power dimensions. Russia, Iran’s strategic partner, has provided intelligence on potential targets to Tehran — a direct counter to US and Israeli intelligence advantages. China, despite being closely economically tied to Iran, has dispatched a special envoy to the region and is openly calling for a ceasefire and return to negotiations, driven primarily by the threat to global energy markets given that China is the world’s largest oil and gas importer.

The European Union has adopted a dual-track approach: condemning Iranian strikes on GCC states while also calling for restraint from the US and Israel. Italy’s Prime Minister Meloni has been working to develop a coordinated EU–GCC diplomatic strategy. European armed forces have deployed an Italian-led air and naval force to the Red Sea to protect critical trade routes.

3. Political Analysis

3.1 US Strategic Objectives

The Trump administration has framed Operation Epic Fury primarily as a counterproliferation effort — preventing Iran from acquiring nuclear weapons — but the broader strategic logic encompasses regime change and the permanent degradation of Iran’s ability to project power through proxies. Secretary of State Marco Rubio stated publicly that the ‘two most powerful air forces in the world’ would ‘take apart this terroristic regime and defang it.’ Trump has signalled further escalation, warning that Iran ‘will be hit very hard’ as the second week of conflict begins.

The administration has also moved to protect commercial interests: Trump ordered the US Development Finance Corporation to provide political risk insurance and guarantees for maritime trade, particularly energy shipments, travelling through the Gulf.

3.2 The Gulf States’ Dilemma

The GCC states occupy an acute strategic dilemma. They host US military infrastructure that Iran is now targeting, yet none of them sought or endorsed this war. They have centuries of cross-Gulf cultural and economic ties with Iran, yet their critical infrastructure is now being struck. Dubai — which built its global brand on being a safe and neutral commercial hub — has been hit multiple times and had its airport temporarily closed, with one fatality reported from intercepted debris on March 8.

The Carnegie Endowment for International Peace has noted that only collective security coordination across the GCC bloc is likely to provide adequate protection, as Iran finds it easier to cajole or coerce individual states. Security coordination to pool interceptor stockpiles and diplomatic coordination to develop negotiated off-ramps are both urgently needed.

3.3 Iran’s Internal Dynamics

The killing of Khamenei has created a succession crisis with no clear resolution. The IRGC has assumed de facto command of military operations, but legitimating a new supreme leader in wartime will be constitutionally and politically complex. The regime faces a classic dilemma: escalating the conflict to demonstrate strength risks catastrophic military losses, while de-escalation could be perceived domestically as surrender, potentially destabilising the regime from within.

Opposition elements and refugees have begun leaving Iran via Azerbaijan and Armenia, with Georgia emerging as a haven for Iranian opposition figures. By March 6, Azerbaijan and Armenia had each received approximately 1,500 refugees, mostly foreign nationals, from Iran.

4. Economic and Market Impact

4.1 Energy Markets

The conflict has triggered a severe global energy shock. Oil prices surged above $90 per barrel — the highest since September 2023 — driven by the declared closure of the Strait of Hormuz, through which approximately 20% of global oil trade passes. Kuwait’s national oil company announced a precautionary production cut on March 8. Saudi Arabia’s largest refinery suspended operations. Iraq also reduced production output.

Qatar’s shutdown of LNG export terminals — representing a fifth of global LNG supply — has created acute shortages in European markets, which remain dependent on Qatari LNG following the disruption of Russian gas supplies. Major shipping carrier Maersk announced it was again rerouting services via the Cape of Good Hope rather than the Suez Canal, adding weeks to transit times and sharply increasing freight costs.

Indicator	Status (as of March 8, 2026)
Oil Price	Above $90/barrel — highest since September 2023
US Gasoline	$5.00/gallon in some markets; national average up 12 cents in a single day
Qatar LNG	Shutdown of ~20% of global LNG supply following drone attacks on terminals
Suez Canal	Maersk rerouting via Cape of Good Hope; weeks added to transit times
Strait of Hormuz	Iran declared closure; vessel passages decreased substantially by March 2
Equities	Dow Jones fell >1,000 points (2.1%) on March 3 — worst day since April 2025
Insurance	War-risk premiums withdrawn or sharply repriced for Hormuz transits

4.2 Aviation and Tourism

The conflict has caused extraordinary disruption to global aviation. More than 1.9 million passengers were affected by 1,900 flight cancellations in and out of the Middle East on March 4 alone. Dubai International Airport — the world’s busiest for international traffic — was temporarily closed after an interception of aerial objects. Emirates suspended all flights before subsequently resuming operations. London Heathrow and other major European hubs reported significant delays as Middle East connecting traffic was disrupted.

The conflict is particularly damaging for Dubai, which has invested decades in building its reputation as a politically neutral global commercial and tourism hub. The strikes directly undermine this brand positioning at a time when the UAE has significant sovereign wealth and infrastructure under development.

4.3 Developing Economy Vulnerability

Beyond the immediate economic disruption, the conflict disproportionately threatens developing economies. Countries in sub-Saharan Africa — particularly Burkina Faso, Burundi, the Central African Republic, the Democratic Republic of Congo, Liberia, and Mozambique — are assessed by Janes as acutely vulnerable given acute fiscal fragility and high dependence on petroleum imports, with limited buffers to absorb sustained price increases.

India, one of the largest purchasers of Persian Gulf crude, faces significant supply disruption. The US Treasury Department issued a 30-day waiver on March 7 to allow Indian refineries to purchase Russian oil that was previously under US sanctions — an emergency accommodation that underscores the scale of the supply shock.

5. Outlook and Scenarios

5.1 Short-Term Trajectory (0–30 Days)

The most probable short-term trajectory is continued escalation. Trump has signalled further intensification of strikes, and the IRGC has both the capability and the political incentive to continue its Gulf-wide targeting campaign. The internal fragmentation of Iranian decision-making reduces the probability of a credible ceasefire offer from Tehran. The risk of accidental escalation — particularly involving civilian aviation, commercial shipping, or Gulf state populations — is elevated.

The six American service member casualties already reported are likely to generate domestic US political pressure both to escalate and, from opposition quarters, to develop an exit strategy. Congressional debate on the legal basis for military action and the absence of explicit authorisation is already underway.

5.2 Medium-Term Scenarios

Scenario	Description and Probability Assessment
Rapid De-escalation	China-mediated ceasefire within 2–4 weeks; oil prices normalise; Iran accepts interim nuclear moratorium. Low probability given IRGC’s current posture.
Managed Conflict	US–Israel strikes degrade IRGC capability over 4–8 weeks; Gulf states maintain neutrality; Strait of Hormuz partially reopens. Moderate probability.
Regional Conflagration	Houthis intensify Red Sea attacks; Iran activates Hezbollah and Iraqi proxies; conflict spreads to Lebanon, Iraq. Higher risk if US escalates to Iranian oil infrastructure.
Regime Collapse	Sustained strikes + economic collapse + internal opposition cause rapid fragmentation of the Islamic Republic. Uncertain successor, potential for extended instability.

6. Pathways to Resolution

6.1 Diplomatic Off-Ramps

The most credible diplomatic pathway runs through Beijing. China has both the economic leverage over Iran and the strategic interest in a ceasefire that no other major power combines. A Chinese-mediated framework — potentially involving a nuclear monitoring moratorium in exchange for a cessation of strikes — is the most viable near-term off-ramp. The UN Secretary-General could provide multilateral legitimacy for such a framework.

Qatar, despite having been struck, retains unique experience as a mediator between the US and Iran. Its continued willingness to engage diplomatically — were Iran to guarantee its neutrality — represents a potentially valuable back-channel. Oman plays a similar role and has the additional credibility of having been targeted despite facilitating talks, which paradoxically reinforces its neutral status.

6.2 GCC Collective Security

For the Gulf states, the structural solution is deeper collective security integration. As the Carnegie Endowment analysis notes, Iran finds it easier to coerce individual GCC members than a unified bloc. Pooled air and missile defence intercept capabilities, joint intelligence sharing, and coordinated diplomatic positioning would both improve defensive resilience and strengthen the Gulf states’ hand in any eventual negotiations.

Critically, the GCC states should resist US pressure to participate directly in offensive operations against Iran. Doing so would deepen their exposure to Iranian retaliation without materially improving the military outcome, while further radicalising Iranian public opinion against them.

6.3 Long-Term Structural Requirements

Any durable resolution requires addressing the three structural drivers of the conflict: Iran’s nuclear programme, the regional proxy architecture, and the energy security dependencies that give both Iran and the conflict broader geopolitical significance. A genuine post-conflict settlement would need to include verifiable nuclear constraints, an architecture for reducing proxy-state activity across the Levant and Gulf, and mechanisms for reintegrating Iran into regional economic structures.

The conflict also exposes the fragility of the global energy transition. As one analyst notes, as long as strategic decisions and conflicts are tied to fossil fuel supply chains, climate goals remain exposed to geopolitical instability. Accelerating energy diversification — both in the Gulf and among import-dependent economies — reduces the systemic leverage that makes the Strait of Hormuz one of the world’s most dangerous chokepoints.

7. Conclusion

The 2026 Iran–Gulf War represents a structural inflection point in Middle Eastern geopolitics. The decapitation of Iran’s supreme leadership, the unprecedented simultaneous targeting of all GCC states, the disruption of the Strait of Hormuz, and the shutdown of a fifth of global LNG supply have combined to create the most severe regional crisis in two decades. The conflict’s outcome will reshape the regional security architecture, the global energy order, and the credibility of both US power projection and Iranian deterrence for years to come.

The immediate priority is preventing further escalation, particularly into Gulf state civilian populations and critical global energy infrastructure. The medium-term priority is creating a credible diplomatic framework — most plausibly through Chinese mediation — that can produce a sustainable ceasefire. The long-term challenge is constructing a regional security architecture that reduces the structural tensions that made this conflict possible: nuclear ambitions, proxy warfare, and fossil fuel dependency.

The international community has weeks, not months, to prevent this from becoming a protracted war of attrition with consequences that extend far beyond the Gulf.
