What Happened
- On February 28, 2026, the United States and Israel launched coordinated military strikes across Iran, targeting military command centres, air-defence systems, missile sites, and key regime infrastructure.
- Iranian Supreme Leader Ayatollah Ali Khamenei (86) was killed in the strikes — confirmed by both Iranian state media and the US President.
- Iran retaliated with ballistic missiles and drone attacks on US military assets and allied nations across the region, including Israel, Saudi Arabia, UAE, Bahrain, Kuwait, Qatar, and Jordan.
- US President Trump stated the operation was proceeding "substantially ahead of schedule" while warning of a potentially prolonged conflict, indicating the campaign could last "four to five weeks."
- Six US service members were killed in Iranian counter-strikes; Iran reported over 200 deaths from American strikes.
- The US Embassy in Riyadh was struck by drones; Ali al-Salem Air Base in Kuwait was targeted; Bahrain's US 5th Fleet headquarters in Manama was hit.

The Concept of Deterrence and Escalation in International Relations
Deterrence theory holds that states can prevent attacks by convincing potential aggressors that the costs of aggression will outweigh any gain. The US-Iran dynamic had long operated on a framework of extended deterrence — where the US nuclear umbrella and conventional military superiority were meant to prevent Iranian escalation. The elimination of the supreme leader represents a collapse of the deterrence equilibrium, triggering what realists call "escalation dominance" uncertainty: neither side can be confident where the escalatory ladder ends.
- Deterrence has two dimensions: deterrence by denial (making attack impossible) and deterrence by punishment (threatening unacceptable retaliation).
- The concept originates with nuclear strategists like Herman Kahn and Bernard Brodie during the Cold War.
- Compellence (forcing a change in behaviour) differs from deterrence (preventing an action) — Trump's campaign mixes both objectives.
- Regional security architectures in West Asia lack a multilateral collective security mechanism analogous to NATO.
Connection to this news: The US-Israeli strike and Iran's retaliatory spread across multiple Gulf states illustrates how deterrence failure can trigger rapid regional escalation, destabilising entire sub-systems.
Role of the United Nations Security Council (UNSC) in Conflict Resolution
The UN Charter (Chapter VII) authorises the Security Council to determine the existence of threats to peace and take enforcement action. However, the P5 veto structure limits UNSC effectiveness when a permanent member (the US) is itself a party to the conflict. Iran has historically been subject to UNSC resolutions (notably 1737, 1747, 1803) for its nuclear programme, while the US invokes Article 51 (right to self-defence) to justify unilateral military action.
- Article 51 of the UN Charter recognises the inherent right of self-defence, including collective self-defence, until the Security Council acts.
- Chapter VI covers peaceful settlement of disputes; Chapter VII covers enforcement actions (including authorisation of force).
- The UNSC has 5 permanent members (P5: US, UK, France, Russia, China) each with veto power, and 10 non-permanent members elected for 2-year terms.
- UN General Assembly can pass non-binding resolutions under the "Uniting for Peace" procedure (Resolution 377) when the UNSC is deadlocked.
Connection to this news: With the US as a belligerent, the UNSC cannot authorise or restrain this conflict through Chapter VII — illustrating the structural limits of the UN collective security system when a veto-wielding power is a party to armed conflict.
Iran's Nuclear Programme and Geopolitical Significance
Iran's nuclear programme has been central to West Asian geopolitics for two decades. The 2015 JCPOA (Joint Comprehensive Plan of Action) imposed limits on uranium enrichment in exchange for sanctions relief; the US withdrew in 2018 under Trump's "maximum pressure" policy. Iran subsequently accelerated enrichment, reaching 60% purity — a level with no civilian justification. The US-Israeli military operation reportedly targeted nuclear infrastructure alongside conventional military sites, aiming to dismantle Iran's weaponisation pathway.
- JCPOA (Iran Nuclear Deal) parties: Iran, US, UK, France, Germany, Russia, China (P5+1).
- Iran's enrichment limit under JCPOA: 3.67%; post-withdrawal escalation reached 60% U-235 enrichment.
- Weapons-grade uranium requires ~90% enrichment; at 60%, Iran was assessed to be within weeks of weapons-grade material.
- The International Atomic Energy Agency (IAEA) monitors nuclear activities under the NPT Additional Protocol.
- Iran is a signatory to the Nuclear Non-Proliferation Treaty (NPT) but faces persistent IAEA verification concerns.
Connection to this news: The military strikes' targeting of nuclear infrastructure confirms that the nuclear dimension was a key trigger, and Khamenei's death raises fundamental questions about who controls Iran's nuclear assets and command-and-control structures during the conflict.
