What Happened
- On February 28, 2026, the United States and Israel launched coordinated military strikes on Iran — nearly 900 strikes in approximately 12 hours — targeting Iran's ballistic missile infrastructure, air defence systems, military command structures, and nuclear facilities including the Natanz enrichment complex.
- Iran's Supreme Leader Ali Khamenei was reportedly killed in the initial strikes, creating a significant leadership vacuum within Iran's political and military command structure.
- Iran responded by closing the Strait of Hormuz to all foreign shipping and by directing allied groups — including Houthi forces in Yemen — to resume attacks on commercial shipping in the Red Sea and on Israeli territory.
- The operation (codenamed "Operation Epic Fury" by US forces) was framed as being aimed at preventing Iran from acquiring nuclear weapons and dismantling its ballistic missile capabilities.
- As of late February 2026, the conflict has entered its fourth week with no ceasefire in sight and significant disruption to global energy markets.

Iran's Nuclear Program and the JCPOA Framework
Iran's nuclear program has been the central geopolitical dispute in the Middle East for two decades. Iran insists it has the right to peaceful nuclear energy under Article IV of the Nuclear Non-Proliferation Treaty (NPT, 1968), to which it is a signatory. However, Iran's uranium enrichment levels — enriched to as high as 60-90% U-235 by late 2025, versus the 3-5% needed for civilian power reactors and the 90%+ needed for weapons — raised acute proliferation concerns. The IAEA reported insufficient access to verify exclusively peaceful intent. The Joint Comprehensive Plan of Action (JCPOA), signed in July 2015 between Iran and the P5+1 (US, UK, France, Russia, China + Germany), imposed strict limits: maximum 3.67% enrichment, maximum 300 kg of low-enriched uranium stockpile, and reduction of centrifuge count in exchange for sanctions relief. The US withdrew from JCPOA in May 2018 under Trump's first term; Iran progressively exceeded all limits thereafter.
- NPT Article IV: recognises the "inalienable right" of all parties to develop nuclear energy for peaceful purposes.
- NPT Article VI: requires nuclear weapon states to pursue nuclear disarmament — widely criticised as unfulfilled by India, Pakistan, Israel (non-NPT members) and within the NPT framework itself.
- IAEA Additional Protocol: voluntary inspection arrangement that gives inspectors broader access; Iran suspended cooperation with the Additional Protocol progressively after 2019.
- Natanz Enrichment Facility (Isfahan Province): primary uranium enrichment site; partly underground (IR-1 and IR-6 centrifuges); attacked in February 2026 strikes.
- JCPOA: signed July 14, 2015; US withdrawal May 8, 2018; Iran's breakout timeline (to weapons-grade material) assessed at weeks by 2025.
Connection to this news: The February 28 strikes were the culmination of a years-long policy debate about whether diplomacy or force could prevent Iran from crossing the nuclear threshold. The decision to strike — rather than negotiate — marks a fundamental departure from the JCPOA framework and transforms Iran's nuclear program from a diplomatic problem into an active military conflict.
Houthi Movement and Iran's Proxy Network
The Houthis (formally Ansar Allah) are a Zaydi Shia armed movement that controls northwest Yemen, including the capital Sanaa, which they seized in 2015. They are part of Iran's "Axis of Resistance" — a network of armed groups that includes Hezbollah (Lebanon), Hamas (Palestine), and various Iraqi militias. The Houthis demonstrated capability to threaten global shipping when they began attacking commercial vessels in the Red Sea in November 2023 in solidarity with Gaza, requiring the deployment of US and allied naval task forces (Operation Prosperity Guardian) to deter attacks. Following the February 28 strikes on Iran, the Houthis announced they would resume attacks on both commercial shipping and Israeli targets — using Iranian-supplied ballistic missiles and Shahed-series drones.
- Red Sea shipping: approximately 12-15% of global trade passes through the Red Sea/Suez route; Houthi attacks in 2023-24 caused major rerouting around the Cape of Good Hope, adding 10-14 days to voyages.
- Operation Prosperity Guardian: multinational naval force assembled in late 2023 to protect Red Sea shipping from Houthi attacks.
- Houthi weapons: Iranian-supplied Shahed-136 drones, Burkan ballistic missiles, and anti-ship cruise missiles.
- Hezbollah (Lebanon): suffered major leadership losses in late 2024 (assassination of Hassan Nasrallah, September 2024); significantly weakened before the February 2026 strikes.
- Hamas: its leadership and military command in Gaza were severely degraded during the 2023-25 conflict.
Connection to this news: The resumption of Houthi Red Sea attacks after the Iran strikes adds a second front of disruption to global supply chains — compounding the Hormuz closure and creating simultaneous pressure on both the Persian Gulf route and the Suez/Red Sea route for global trade.
US Military Posture in the Middle East
The US maintains the most extensive forward military presence in the Middle East of any external power. Key facilities include: the US Fifth Fleet headquarters in Bahrain; Al-Udeid Air Base in Qatar (the largest US air base outside the continental US, with ~10,000 personnel); Al Dhafra Air Base in the UAE; and multiple air defence and pre-positioned equipment hubs across the region. The legal basis for US military operations in the region is typically either congressional authorisation (AUMF — Authorization for Use of Military Force) or executive claims of inherent Article II constitutional authority. The 2001 AUMF (post-9/11) and 2002 AUMF (Iraq) have been the legal foundations for much US military activity in the region; a specific AUMF for Iran operations would represent a new congressional action.
- US Fifth Fleet (Bahrain): commands all US naval forces in the Middle East, Arabian Gulf, Red Sea, and parts of the Indian Ocean.
- Al-Udeid Air Base (Qatar): primary hub for US Central Command (CENTCOM) air operations across the region.
- Aircraft carrier groups typically deployed to the region: USS Gerald R. Ford-class; each carrier group includes cruisers, destroyers, submarines and air wing.
- Israel's defence relationship with the US: governed by a 10-year Memorandum of Understanding (MOU) on defence assistance signed in 2016 (extended), providing approximately $3.8 billion/year in military aid.
Connection to this news: The February 2026 strikes represent the first direct US military action against Iran proper (previous actions targeted Iranian-backed forces elsewhere), marking a significant escalation in US military involvement in the Middle East since the 2003 Iraq invasion — with lasting implications for regional stability and India's energy security.
