EXECUTIVE SUMMARY

On 28 February 2026, the United States and Israel launched ‘Operation Epic Fury’, a coordinated military campaign against the Islamic Republic of Iran. The operation resulted in the killing of Supreme Leader Ali Khamenei and has since expanded into the most significant armed conflict in the Middle East since the 2003 Iraq War. This case study provides a comprehensive academic analysis of the conflict’s origins, power dynamics, strategic outlook, potential solutions, and the implications for Singapore — a small, open, trade-dependent city-state with significant exposure to energy markets and regional stability.

As of 7 March 2026 — the seventh day of open conflict — US–Israeli airstrikes continue to pummel Iran’s military infrastructure, Iranian retaliatory strikes have targeted Gulf states including Kuwait, Qatar, Saudi Arabia, and Bahrain, and global markets have been severely disrupted. The United Nations Secretary-General has warned the conflict may ‘spiral beyond anyone’s control’.

I. CASE STUDY: BACKGROUND AND CHRONOLOGY

1.1 Historical Context

The United States and Iran have existed in a state of sustained strategic antagonism since the 1979 Islamic Revolution, which ousted the US-backed Shah and established a theocratic republic under Ayatollah Ruhollah Khomeini. Decades of proxy conflicts, sanctions, nuclear brinkmanship, and ideological rivalry formed the structural backdrop against which this war erupted.

Israel’s threat perception has been shaped by Iran’s nuclear programme, its explicit calls for Israel’s destruction, and its material support for Hamas, Hezbollah, Palestinian Islamic Jihad, and the Houthi movement. The 2024 Gaza War and subsequent Iranian direct missile and drone attacks on Israeli territory in April and October 2024 marked a significant crossing of the threshold from proxy to direct confrontation.

1.2 Immediate Triggers

The precise diplomatic and intelligence events leading to the authorisation of Operation Epic Fury have not yet been disclosed in open sources. However, available evidence points to a convergence of factors:

• Continued Iranian enrichment activity near weapons-grade uranium thresholds, assessed by US and Israeli intelligence as crossing a red line.
• Iranian-backed Houthi interdiction of Red Sea shipping lanes causing acute damage to global trade throughout late 2025.
• A collapse of back-channel nuclear negotiations in January 2026.
• A strategic window created by a new US administration under President Donald Trump, perceived as more willing to authorise pre-emptive military action.

II. POWER DYNAMICS

2.1 The US–Israel Axis

The United States brings to this conflict unmatched conventional military superiority, including strategic stealth aircraft capable of penetrating Iranian air defences, fifth-generation fighter jets, carrier battle groups in the Persian Gulf and Eastern Mediterranean, and Tomahawk cruise missile platforms. The White House’s stated objective — effective control of Iranian airspace within four to six weeks — reflects extraordinary confidence in technological dominance.

Israel contributes specialised intelligence, precision strike capability, and deep familiarity with Iranian military architecture honed over decades of covert operations. The joint operation reflects the deepest military integration between the two states in modern history. Critically, Israel has domestic political incentive to pursue the campaign to conclusion, given existential threat framing around Iranian nuclear capability.

However, the US–Israel axis faces significant constraints: the illegality of regime change under international law, the risk of asymmetric Iranian retaliation against civilian and economic infrastructure, the absence of a credible post-conflict governance plan for Iran, and the destabilising effect of Trump’s public statements about selecting Iran’s next leader — which has alienated potential swing-state Arab interlocutors.

2.2 Iran

Iran’s conventional military forces are substantially outmatched by the US–Israel coalition. The killing of Khamenei has decapitated the supreme decision-making authority, creating a dangerous power vacuum in which the Islamic Revolutionary Guard Corps (IRGC) and competing clerical factions may act autonomously and unpredictably.

Iran retains several asymmetric instruments of power. Its ballistic missile and drone arsenal — partially depleted but still operational — enables regional strike capability against US bases and Gulf infrastructure. Its proxy network (Hezbollah, Houthi, Shia militias in Iraq) provides strategic depth and the capacity to internationalise the conflict. Iran’s oil leverage, while diminished under sanctions, contributes to the global energy shock already under way.

Iran’s critical strategic asset is the capacity to impose costs exceeding the US–Israel coalition’s tolerance threshold — not to win conventionally, but to render the occupation or reconstruction of Iran politically and financially prohibitive.

2.3 Russia and China

Russia has emerged as a significant complicating actor. Reports of Russian intelligence sharing — specifically the location of US aircraft — with Iran represent a potentially escalatory intervention that risks direct US–Russia confrontation. Putin’s public framing of the conflict as ‘armed aggression’ aligns with Russia’s broader narrative interest in undermining US-led international order, particularly after Ukraine. Russia has limited formal treaty obligations to Iran but shares a strategic interest in bogging down US power projection.

China’s public posture remains one of restraint and calls for dialogue, consistent with its stated principle of non-interference. However, China is Iran’s largest oil customer under sanctions-era arrangements, and a prolonged conflict destabilising Gulf energy supplies poses direct risks to Chinese industrial activity. Beijing’s behind-the-scenes role in any ceasefire diplomacy may prove decisive.

2.4 Gulf States

Saudi Arabia, the UAE, Kuwait, Qatar, and Bahrain find themselves caught between their security dependence on the US and their geographic exposure to Iranian retaliation. Iranian strikes on Gulf infrastructure represent a direct escalation, potentially drawing these states more explicitly into the conflict. The UK’s pledge to defend Saudi Arabia and the deployment of British naval and air assets add a NATO-adjacent dimension to Gulf security.

2.5 The Multilateral and Normative Arena

The United Nations has been effectively marginalised. UN Secretary-General Guterres’ warnings carry moral authority but no enforcement mechanism. Russia’s veto power in the Security Council forecloses any binding resolution. International humanitarian law has been severely strained by civilian casualties in Tehran, Beirut, and across the region. The trajectory of international consensus is deteriorating rapidly, with the Global South largely hostile to US–Israeli framing of the intervention.

III. STRATEGIC OUTLOOK

3.1 Short-Term Outlook (Weeks 2–6)

The US–Israel coalition is likely to continue intensifying strikes on Iranian military command, nuclear facilities, and air defence systems. The stated US objective of controlling Iranian airspace within four to six weeks suggests a planned degradation campaign rather than immediate ground invasion. However, the failure to destroy Iran’s command-and-control network after seven days — as assessed by UK intelligence — implies the campaign may take longer than projected.

Iranian retaliation is expected to continue and possibly intensify, with heightened risk of major infrastructure strikes on Gulf oil facilities. A disruption to Saudi Aramco production capacity would trigger a global oil shock significantly exceeding current price movements. The risk of miscalculation — including the accidental targeting of Russian assets or the triggering of a retaliatory strike that kills large numbers of American personnel — remains elevated.

3.2 Medium-Term Outlook (Months 1–6)

Three scenarios dominate the medium-term analytical landscape:

• Scenario A — Regime Collapse and Political Fragmentation: Iranian state institutions fracture following the power vacuum created by Khamenei’s death. A post-war governance arrangement is imposed by the US and its allies, analogous to post-2003 Iraq. This scenario carries significant risk of protracted insurgency, humanitarian catastrophe, and regional instability.
• Scenario B — Negotiated Ceasefire: Back-channel diplomacy, potentially mediated by China, Qatar, or Oman, produces a ceasefire agreement. Iran agrees to verifiable nuclear rollback in exchange for cessation of strikes and sanctions relief. This scenario is analytically plausible but politically difficult given Trump’s demand for ‘unconditional surrender’.
• Scenario C — Protracted Attrition: Neither side achieves decisive victory. Iran absorbs strikes while maintaining asymmetric retaliation capacity. The conflict drags into a multi-month attritional campaign with massive civilian casualties, energy market disruption, and global recession risk.

Scenario C is currently assessed as most probable given the structural dynamics outlined above.

3.3 Long-Term Outlook (1–5 Years)

Regardless of near-term military outcomes, the conflict is likely to produce lasting structural changes to the Middle East regional order, the global energy system, US hegemony, and the international rules-based order. The legitimacy cost of assassination of a sovereign state’s leader and the explicit US demand to select Iran’s successor will significantly accelerate the global south’s alignment against US-led multilateralism.

IV. PROPOSED SOLUTIONS AND PATHWAYS TO DE-ESCALATION

4.1 Immediate Ceasefire Architecture

The most urgent priority is halting the expansion of the conflict before it crosses into a regional war involving multiple state actors in direct confrontation. A workable ceasefire architecture would require:

• A third-party mediator acceptable to all parties — most plausibly Qatar, which maintains diplomatic relations with both the US and Iran and has historically served as an intermediary channel.
• A mutual cessation of offensive strikes, including US–Israeli airstrikes on Iran and Iranian missile/drone attacks on Gulf states.
• Emergency UN humanitarian corridors into Iran to address the civilian casualty crisis.
• A commitment by the US to refrain from selecting or endorsing specific candidates for Iranian political succession, which is a non-starter under international law and fundamentally incompatible with Iranian sovereignty.

4.2 Nuclear Framework Resolution

The underlying driver of the conflict — Iran’s nuclear programme — requires a durable diplomatic resolution. The JCPOA framework, abandoned by the US in 2018, provides a technical template. A revised agreement would need to address verification mechanisms distrusted by Israel, incorporate enrichment caps, and provide Iran with credible sanctions relief that cannot be unilaterally reversed by subsequent US administrations. Chinese and European engagement is essential to create a multilateral guarantee architecture.

4.3 Governance Transition in Iran

The killing of Khamenei creates a succession crisis that must be handled by Iranians, not external powers. Any externally imposed leadership arrangement will lack legitimacy and generate insurgent resistance. International actors should commit to a framework of non-interference in the succession process while establishing clear red lines around the acquisition of nuclear weapons by any successor regime.

4.4 Regional Security Architecture

A lasting solution requires a broader regional security dialogue inclusive of Israel, the Arab Gulf states, Iran, Turkey, and major external powers. The Abraham Accords framework provides one building block, but must be extended to address Iranian security concerns and the Palestinian question. A Helsinki-style regional security conference, though analytically distant from current conditions, represents the structural solution to the cyclical escalation dynamic that has plagued the region for decades.

V. IMPACT ON SINGAPORE

5.1 Energy Security and Oil Prices

Singapore is entirely dependent on imported energy. As a major refining hub in Southeast Asia — home to one of the world’s largest refining centres on Jurong Island — Singapore’s energy sector is acutely exposed to disruptions in Middle East crude oil supply. Brent crude has already broken above $85 per barrel, and any escalation targeting Saudi Arabian or UAE oil infrastructure could drive prices to levels not seen since the 2008 crisis.

Higher energy costs will flow directly into Singapore’s electricity tariffs — households have already been warned of higher bills — and will increase production costs across manufacturing, chemicals, and petrochemicals. The refining margin environment may paradoxically benefit Singapore-based refiners in the short term if regional refining capacity is disrupted, but sustained price elevation will weigh on downstream demand.

5.2 Shipping and Trade Disruption

Singapore’s position as the world’s second-busiest port makes it structurally dependent on the free flow of maritime trade through key chokepoints including the Strait of Hormuz and the Red Sea. Iranian threats to Gulf shipping and any potential Hormuz closure scenario would be catastrophic for global trade flows and would significantly increase shipping costs and transit times for goods moving between Asia, Europe, and the Middle East.

Singapore’s port, which handles approximately 37 million TEUs annually, would face rerouting pressures and supply chain disruptions affecting electronics, chemicals, and consumer goods flows. Insurance premiums for vessels in the Persian Gulf and Red Sea have already risen sharply, increasing shipping costs globally.

5.3 Financial Markets and Investment

Singapore’s status as a major financial centre exposes it to the broader global market sell-off already under way. The Singapore Exchange (SGX) would be expected to track US, European, and Asian market declines. Risk-off capital flows typically benefit the Singapore dollar as a safe haven in the Asian context, but the counteracting effect of energy price inflation complicates this dynamic.

Singapore’s sovereign wealth funds — GIC and Temasek — hold substantial global equity portfolios. A prolonged conflict driving a global recession scenario would impair returns and could require strategic portfolio rebalancing. Foreign direct investment flows into Singapore may be temporarily disrupted as corporates defer major capital allocation decisions.

5.4 Diplomatic and Strategic Positioning

Singapore’s diplomatic doctrine of principled neutrality, articulated through decades of consistent application of international law and the UN Charter, is placed under significant strain. Singapore has historically maintained constructive relations with both the United States — its most important security partner — and Arab Gulf states, which are significant trade and investment partners. Singapore has also maintained working relations with Iran, primarily through trade channels.

The Singapore government will be expected to call for restraint and adherence to international law, consistent with its long-standing foreign policy positions. However, Singapore’s ability to influence the trajectory of the conflict is structurally limited given its size. The government’s most consequential decisions will be domestic: energy stockpile management, market stabilisation measures, and communication with Singapore’s Muslim community, for whom the conflict carries significant resonance.

5.5 Singapore’s Muslim Community and Social Cohesion

Approximately 15% of Singapore’s resident population is Malay-Muslim. Conflicts in the Middle East, particularly those perceived as targeting Muslim populations, historically generate elevated social sensitivities within Singapore’s multiracial society. The government will need to balance transparent, empathetic communication with vigilance against foreign interference in domestic religious discourse. The Internal Security Department (ISD) and the community engagement frameworks built through the Inter-Racial and Religious Confidence Circles (IRCCs) will be important instruments in maintaining social cohesion.

5.6 Summary: Singapore Risk Matrix

Risk Domain	Severity	Likelihood	Timeframe
Energy Price Inflation	HIGH	Certain	Immediate
Port / Shipping Disruption	HIGH	Probable	Near-term
Financial Market Volatility	MEDIUM-HIGH	Certain	Immediate
Recession / GDP Impact	MEDIUM	Possible	Medium-term
Social Cohesion Pressure	MEDIUM	Possible	Near-term
Direct Security Threat	LOW	Unlikely	Long-term

VI. CONCLUSION

Operation Epic Fury represents a watershed moment in the post-Cold War international order. The deliberate assassination of a sovereign state’s supreme leader, the explicit demand for unconditional surrender, and the US announcement of intent to select Iran’s successor government collectively signal a willingness to suspend the foundational norms of the UN Charter in pursuit of security objectives. Whether this produces a durable strategic outcome or a generational cycle of instability will depend heavily on the decisions made in the coming weeks.

For Singapore, the conflict is a powerful reminder of the acute vulnerability of small, open, trade-dependent states to geopolitical shocks originating far beyond their borders and far beyond their capacity to influence. Singapore’s best instruments are its economic resilience buffers — strategic reserves, energy stockpiles, MAS monetary policy tools — and its diplomatic capital, which should be deployed to support multilateral de-escalation efforts through ASEAN and the UN.

The scholarly and policy communities should resist the false binary of ‘US victory’ versus ‘Iranian survival’. The more consequential question is whether the international community can construct a post-conflict architecture that addresses the legitimate security concerns of all regional actors, prevents nuclear proliferation, and re-establishes the norms of sovereignty and non-interference that underpin the international order on which all small states depend.
