Operation Epic Fury — Context and Legal Framework of Armed Conflict
Operation Epic Fury is the US military codename for joint US-Israeli strikes on Iran that began on February 28, 2026 (Israel's codename: Operation Roaring Lion). The stated objectives were to dismantle Iran's ballistic missile architecture, destroy nuclear support facilities, and target command-and-control nodes. Nearly 900 strikes were launched in the first 12 hours. Iran's Supreme Leader Ali Khamenei was killed in the initial wave. The operation raises foundational questions in international law: under the UN Charter (Article 51), the use of force is permitted only in self-defence or with Security Council authorisation under Chapter VII.
- UN Charter Article 2(4): prohibits threat or use of force against territorial integrity of any state
- UN Charter Article 51: exception for individual or collective self-defence until the Security Council acts
- The US invoked no Security Council authorisation; the legal basis claimed was pre-emptive self-defence against Iran's nuclear program
- Early strikes killed Supreme Leader Ali Khamenei along with dozens of senior officials
- The US early-phase munitions cost: estimated $5.6 billion (Washington Post, March 9)
- Gen. Caine confirmed strikes on 5,000+ targets and 50+ Iranian naval vessels by March 10
Connection to this news: The continued escalation and announcement of "most intense" strikes signals the US moving from initial degradation to sustained attrition operations, raising the risk of wider regional entanglement.
The Islamic Revolutionary Guard Corps (IRGC) — Iran's Parallel Military
The IRGC (Sepah-e Pasdaran-e Enqelab-e Eslami) was founded in 1979 following the Islamic Revolution to defend the new republic against internal and external threats, and to counterbalance the regular armed forces. Unlike the conventional military, the IRGC answers directly to the Supreme Leader. It commands at least 150,000 personnel, with its own ground forces, navy, aerospace division, and the elite Quds Force (external operations). The Basij paramilitary, a subordinate force, adds approximately 90,000 active personnel. The IRGC also oversees Iran's nuclear program and controls vast economic interests spanning construction, energy, banking, and shipping.
- Founded: 1979, shortly after the Islamic Revolution
- Commands: Ground forces, Navy, Aerospace Force, Quds Force (external ops), Basij
- The IRGC's Quds Force is designated a Foreign Terrorist Organization by the US (2019)
- The IRGC as a whole was placed on the US Foreign Terrorist Organization list in 2019 — the first time a state military entity received this designation
- Controls Iran's ballistic missile program and nuclear security infrastructure
- In 2022, the IRGC created a new "Command for the Protection and Security of Nuclear Centres"
- US and EU both have extensive IRGC-related sanctions regimes
Connection to this news: The IRGC is the primary adversary in Operation Epic Fury — its naval vessels, missile complexes, and command nodes are the stated targets of US strikes.
Iran's Nuclear Program and JCPOA — Background
The Joint Comprehensive Plan of Action (JCPOA), signed on July 14, 2015 in Vienna, was a multilateral agreement between Iran and the P5+1 (the five permanent UN Security Council members — US, UK, France, Russia, China — plus Germany) and the EU. It imposed limits on Iran's uranium enrichment, centrifuge count, and stockpiles in exchange for phased sanctions relief. The US unilaterally withdrew in 2018 under President Trump's "maximum pressure" policy. Iran subsequently accelerated enrichment, and by 2026 was assessed to be on the threshold of weapons capability — a key stated justification for Operation Epic Fury.
- JCPOA signed: July 14, 2015 (Vienna); enforced from January 2016
- P5+1: US, UK, France, Russia, China + Germany (+ EU)
- US withdrawal: May 2018 (Trump's first term)
- Iran's enrichment post-2018: Escalated from 3.67% (JCPOA limit) to 60%+ purity; near weapons-grade is 90%+
- IAEA reports since 2022 documented Iran stockpiling enriched uranium far beyond JCPOA limits
- JCPOA was a non-binding executive agreement, not ratified as a treaty by the US Senate
Connection to this news: Iran's nuclear program and the collapse of the JCPOA framework are the proximate causes of Operation Epic Fury, with the US citing Iran's breakout timeline as justification for pre-emptive military action.
