What Happened
- Iran launched missile attacks against Israel in response to US President Donald Trump's threats of "weeks of strikes" against Iran's nuclear and energy infrastructure.
- The attacks follow the larger conflict arc that began on February 28, 2026, when the US and Israel jointly struck Iran's nuclear facilities (Natanz, Fordow, Isfahan), ballistic missile sites, and energy infrastructure.
- Trump threatened that if Iran does not reopen the Strait of Hormuz by April 6, the US would conduct "extensive attacks" on Iranian energy sites, dramatically escalating the conflict's potential scope.
- Iran has been retaliating by launching drones and ballistic missiles at Israeli targets and US military bases in Bahrain, Jordan, Kuwait, Qatar, Saudi Arabia, and the UAE — creating a multi-front conflict across the Gulf.
- Iran's missile and drone attacks represent a shift from the defensive posture of 2024–2025 to direct offensive operations, as Iran's leadership calculates that accommodation is not an option.

Iran's Nuclear Programme: History and the JCPOA
Iran's civilian nuclear programme dates to the 1950s (under the Shah, with US assistance under "Atoms for Peace"). After the 1979 Islamic Revolution, Iran developed its nuclear programme independently. Suspected weaponisation efforts were revealed in 2002, leading to IAEA scrutiny. Iran insists its programme is entirely civilian, but its enrichment of uranium to weapons-grade proximity raised international concerns. The Joint Comprehensive Plan of Action (JCPOA), signed in July 2015, was the international community's negotiated solution.
- JCPOA signatories: Iran, USA, UK, France, Germany, Russia, China (P5+1 / E3+3) — signed July 14, 2015.
- Key JCPOA restrictions on Iran: maximum 5,060 IR-1 centrifuges, uranium enrichment capped at 3.67%, stockpile limit of 300 kg enriched uranium, no enrichment at Fordow for 15 years.
- US withdrew from JCPOA in May 2018 under Trump's first term; Iran gradually rolled back JCPOA commitments in response.
- By 2025, Iran was enriching uranium to 60% at Fordow — significantly above JCPOA limits; Iran possessed enough 60% enriched uranium that could theoretically be further enriched to weapons-grade.
- Key facilities attacked: Natanz (primary enrichment facility, partially underground), Fordow (deep underground, near Qom), Isfahan (conversion facility).
- IAEA stated there was "no evidence of a structured nuclear weapons program" when the 2026 war began.
Connection to this news: Iran's missile retaliation against Israel is partly a direct response to what Iran frames as an unprovoked destruction of its sovereign nuclear infrastructure — the attacks on Natanz and Fordow. The nuclear issue is the underlying casus belli for the US-Israel side of the conflict.
US-Israel Strategic Relationship and West Asia Dynamics
The United States and Israel maintain one of the world's most enduring bilateral strategic partnerships. The US has been Israel's primary security guarantor since Israel's establishment in 1948, providing military aid, intelligence sharing, diplomatic protection at the UNSC (US has vetoed dozens of anti-Israel resolutions), and strong people-to-people ties. The Trump administration's second term (2025–) has been characterised by an even stronger pro-Israel stance, including explicit threats against Iran's nuclear programme.
- US annual military aid to Israel: approximately $3.8 billion under the 2019 Memorandum of Understanding (MOU); increased significantly in 2023–2024 amid the Gaza conflict.
- US has vetoed approximately 45 UNSC resolutions critical of Israel since 1972.
- The Abraham Accords (2020): Normalisation agreements between Israel and UAE, Bahrain, Sudan, and Morocco — brokered by the Trump administration's first term; these shifted regional alignments.
- Iran-backed "Axis of Resistance": includes Hamas (Gaza), Hezbollah (Lebanon), Houthis (Yemen), various Iraqi militias — seen by Israel/US as a strategic encirclement threat.
- The US 5th Fleet, based in Bahrain, is the primary US naval force in the Gulf; Iran's attacks on Gulf US bases represent a significant escalation targeting American military personnel.
Connection to this news: Iran's missile attacks on Israel (and US Gulf bases) are a direct response to the US-Israel joint strike campaign — the conflict has moved from asymmetric proxy warfare (Houthis, Hamas) to direct state-on-state military exchange, representing a qualitative escalation.
Non-Proliferation, Nuclear Weapons, and the NPT Regime
The Nuclear Non-Proliferation Treaty (NPT), in force since 1970, aims to prevent the spread of nuclear weapons, promote disarmament, and ensure peaceful use of nuclear energy. Iran is an NPT signatory (unlike India, Pakistan, and Israel). The NPT has three pillars: non-proliferation (non-nuclear states won't acquire weapons), disarmament (nuclear states commit to eventual disarmament), and peaceful use (right to civilian nuclear technology).
- NPT opened for signature: 1968; entered into force: March 5, 1970; indefinitely extended in 1995.
- NPT currently has 191 states parties (near-universal membership); non-signatories: India, Pakistan, Israel (de facto nuclear states), North Korea (withdrew in 2003).
- IAEA (International Atomic Energy Agency, Vienna) is the NPT's verification body; conducts safeguards inspections.
- Iran has limited IAEA inspector access at various points, creating "safeguards compliance" disputes.
- The NPT's "Grand Bargain": non-nuclear states accept not developing weapons in exchange for peaceful nuclear technology access and a promise of disarmament by nuclear-weapon states — the latter obligation has been widely criticised as unmet.
- Comprehensive Nuclear Test Ban Treaty (CTBT): signed 1996, not yet in force (requires ratification by 44 specific states including India, Pakistan, USA, China, Israel, North Korea — none have ratified).
Connection to this news: The US justification for striking Iran's nuclear facilities rests on NPT non-proliferation norms — the concern that Iran was approaching breakout capability. Iran's continued enrichment above JCPOA limits provided the legal and political argument, even if IAEA found no evidence of a weapons programme.
