What Happened
- The US-Israel military campaign against Iran crossed the one-month mark at the end of March 2026, beginning with strikes on February 28, 2026 that killed Supreme Leader Ali Khamenei along with his daughter, son-in-law, grandchild, and other family members.
- Seven top Iranian security officials were confirmed killed in the first wave, including Defence Minister Aziz Nasirzadeh, IRGC Commander Mohammad Pakpour, Defence Council Secretary Ali Shamkhani, and four Ministry of Intelligence heads.
- On March 8, 2026, Mojtaba Khamenei — son of the slain Supreme Leader — was elected as the new Supreme Leader, with IRGC and senior officials pledging allegiance.
- Iran's state broadcaster IRIB headquarters in Tehran was destroyed in an Israeli air operation on March 3, 2026, alongside destruction of the IRGC Malek-Ashtar complex.
- Iran retaliated with over 80 waves of missile and drone strikes against Israel and US military facilities in Kuwait, Bahrain, Qatar, Jordan, Saudi Arabia, and the UAE; a strike on a Saudi air base wounded at least 15 US servicemen.
- As of late March 2026, Iran's Health Ministry reported at least 1,937 killed and over 24,800 injured — including 4,000 women and 1,621 children — from US-Israeli strikes.
- Iran imposed a selective blockade on the Strait of Hormuz, stalling approximately 150 freight ships and tankers and removing up to 20 million barrels per day from global oil markets; Brent crude peaked at $126 per barrel.

The Supreme Leader Institution in Iran's Political System
Iran's political system is a hybrid of theocracy and republicanism, established by Ayatollah Khomeini after the 1979 Islamic Revolution. The Supreme Leader (Rahbar) is the highest authority in the country, overseeing the military (including IRGC), judiciary, state media, and foreign policy. The Guardian Council (12 members, 6 appointed by Supreme Leader) vets all electoral candidates. The Supreme Leader is elected for life by the Assembly of Experts — a body of 88 elected Islamic scholars. Ali Khamenei served as Supreme Leader from 1989 until his death in 2026; his son Mojtaba Khamenei's election represents the first dynastic succession in the Islamic Republic.
- IRGC (Islamic Revolutionary Guard Corps): an elite parallel military force separate from the regular army, reporting directly to the Supreme Leader; also controls the Quds Force (external operations)
- The Assembly of Experts holds elections every 8 years; it also has theoretical power to dismiss the Supreme Leader
- Velayat-e Faqih (Guardianship of the Islamic Jurist): the constitutional principle underpinning the Supreme Leader's authority
- Mojtaba Khamenei's election is the first hereditary succession in the Islamic Republic — a significant structural change
Connection to this news: The decapitation of Iran's entire top security leadership — the Supreme Leader, Defence Minister, IRGC commander — is unprecedented; the succession process and loyalties of the new leadership will shape Iran's war strategy and willingness to negotiate.
Proxy Networks and Iran's "Axis of Resistance"
Iran has built a network of non-state armed groups across West Asia — collectively called the "Axis of Resistance" — to project power and deter adversaries. Key groups include: Hezbollah (Lebanon), Hamas and Palestinian Islamic Jihad (Gaza/West Bank), Houthi movement (Yemen), Popular Mobilisation Forces (Iraq/PMF), and various Syrian militias. Iran's IRGC Quds Force trains, arms, and finances these groups. The concept mirrors Cold War-era proxy warfare — using third parties to fight wars without direct state-to-state engagement. Many US facilities in Kuwait, Bahrain, Qatar, Jordan, and Saudi Arabia that were struck by Iranian missiles host these forces as part of CENTCOM's regional footprint.
- Hezbollah is often called Iran's most capable proxy — with an estimated 100,000+ rockets and missiles
- PMF in Iraq was formally integrated into the Iraqi state military structure in 2016
- Houthis controls most of northern Yemen including Sanaa and the Red Sea coast — enabling attacks on international shipping
- Iran's annual budget for proxy support has been estimated at $1–2 billion
Connection to this news: Iran's 80+ waves of retaliatory strikes using missiles and drones across multiple countries demonstrate the activation of its regional deterrence network, a strategic capability built over decades as an asymmetric counter to US-Israeli conventional superiority.
Laws of War: Proportionality, Military Necessity, and Civilian Casualties
International Humanitarian Law (IHL) — governed by the Geneva Conventions (1949), Additional Protocols (1977), and customary international law — sets binding rules on the conduct of hostilities. Core principles include Distinction (between combatants and civilians), Proportionality (civilian harm must not be excessive relative to military advantage), Precaution (steps must be taken to minimise civilian casualties), and Military Necessity (only acts that are necessary to achieve a legitimate military objective are permissible). The deaths of over 1,600 children and 4,000 women in US-Israeli strikes, and Iran's indiscriminate missile salvoes against populated areas and foreign military bases, raise IHL accountability questions on both sides.
- The International Criminal Court (ICC) can investigate war crimes regardless of the nationality of the perpetrators if the crime was committed on the territory of a member state
- Neither the US nor Iran is a party to the ICC
- Israel withdrew its accession to the Rome Statute in 2024 ahead of ICJ proceedings
- Common Article 3 of the Geneva Conventions covers non-international armed conflicts
Connection to this news: The casualty figures — over 24,800 injured including children — and the targeting of Iran's state broadcaster and civilian infrastructure put both sides' conduct under IHL scrutiny, a key Mains GS2 ethics dimension.
