What Happened
- Following the US-Israel joint strikes on Iran beginning February 28, 2026 (which included the killing of Iranian Supreme Leader Ali Khamenei), the conflict rapidly escalated beyond its initial theatre.
- Iran launched retaliatory missile and drone strikes on US military bases across the Gulf (Kuwait, Saudi Arabia) and on Gulf state civilian infrastructure, including oil refineries, desalination plants, and airports.
- The Islamic Revolutionary Guard Corps (IRGC) warned against vessel passage through the Strait of Hormuz, effectively halting shipping traffic and triggering the largest global oil supply disruption on record.
- Lebanon was drawn into the conflict when Hezbollah attacked Israel in solidarity with Iran; Iraqi Shia militias and Houthi rebels in Yemen also activated, creating a multi-front conflict.
- US forces launched a military campaign on March 19, 2026, to reopen the Strait of Hormuz; the International Energy Agency characterised the disruption as the "largest supply disruption in the history of the global oil market."

The Strait of Hormuz: The World's Most Critical Energy Chokepoint
The Strait of Hormuz is a narrow waterway approximately 33–96 km wide, located between Iran (north) and Oman (south), connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the single most critical oil and gas chokepoint in the world.
- Approximately 15 million barrels per day of crude oil transited the strait in 2025 — roughly 34% of all global crude oil trade (US Energy Information Administration).
- About one-fifth of global LNG trade also transits the strait, primarily from Qatar.
- 82% of crude flowing through Hormuz goes to Asian markets (China, India, Japan, South Korea).
- Pipeline bypass capacity: approximately 2.6 million b/d via Saudi Arabia's East-West Pipeline (Petroline) to Yanbu on the Red Sea, and the UAE's Abu Dhabi Crude Oil Pipeline (ADCOP) to Fujairah.
- The Strait narrows to a two-lane shipping corridor of approximately 2 miles each way.
- India imports nearly two-thirds of its crude oil through the strait.
Connection to this news: Iran's ability to threaten Hormuz closure — and the resulting surge in Brent crude above $120/barrel — illustrates how geopolitical conflict in a narrow waterway can instantaneously destabilise global energy markets and food supply chains, directly impacting Indian consumers and the economy.
Iran's "Axis of Resistance": Proxy Network and Multi-Front Strategy
Iran's strategic doctrine relies on a network of allied non-state armed groups — the "Axis of Resistance" — to deter adversaries and project power across the region without direct state-to-state military confrontation.
- Hezbollah (Lebanon): largest and most capable proxy; has 150,000+ rockets/missiles, runs social services, holds parliamentary seats.
- Hamas and Islamic Jihad (Gaza): Palestinian militant groups supported with funding, training, and weapons.
- Houthi rebels (Ansar Allah) (Yemen): launched hundreds of ballistic missiles and drones at Israel and attacked Red Sea shipping from 2023; part of the broader multi-front strategy.
- Iraqi Shia militias (Kata'ib Hezbollah, PMF groups): have attacked US bases in Iraq and Syria.
- This network allows Iran to impose costs on the US and Israel while maintaining "plausible deniability" and avoiding direct nuclear-threshold confrontation.
- The concept is linked to Iran's "Forward Defence" doctrine — fighting adversaries far from Iranian territory.
Connection to this news: The multi-front character of the 2026 Iran war — with Hezbollah in Lebanon, Houthis in Yemen, and Iraqi militias simultaneously activated — is precisely the Axis of Resistance strategy operationalised, demonstrating how proxy networks convert a bilateral conflict into a regional war.
Geopolitical Spillover: Nuclear Proliferation and Regional Power Dynamics
A major concern in any Iran conflict is the risk of nuclear escalation and the collapse of the non-proliferation architecture, particularly if the conflict destroys Iran's nuclear infrastructure or pushes Iran toward weaponisation.
- Iran's nuclear programme has been subject to multiple rounds of international sanctions and negotiations.
- The Joint Comprehensive Plan of Action (JCPOA), signed in 2015 between Iran (P5+1: US, UK, France, Russia, China + Germany), limited Iran's uranium enrichment in exchange for sanctions relief.
- The US withdrew from JCPOA in 2018 (Trump administration); Iran progressively violated enrichment limits; uranium enriched to 60% purity reported by IAEA before 2026 conflict.
- The Nuclear Non-Proliferation Treaty (NPT) — signed 1968, in force 1970 — is the cornerstone of global non-proliferation; 191 states are party to it. Iran is a signatory.
- Destruction of Iranian nuclear facilities during the conflict raised fears of radiation leaks and accelerated breakout timelines for other regional actors (Saudi Arabia, Turkey).
Connection to this news: The spillover risk in the Iran war extends beyond conventional military escalation — the destruction of nuclear infrastructure and the collapse of the JCPOA framework represent existential risks to global non-proliferation architecture, directly relevant to UPSC Mains questions on nuclear security.
