What Happened
- US President Trump, in his 2026 State of the Union address (February 24, 2026), reiterated that Iran would never be allowed to build a nuclear weapon, claiming Tehran's leaders were "at this moment again pursuing their sinister nuclear ambitions"
- Trump claimed Iran was developing missiles that could "soon" reach the United States, stating Iran has already built missiles capable of striking Europe and US overseas bases
- Iran's Foreign Ministry rejected these claims as "big lies," with Foreign Minister Abbas Araghchi stating Iran is "not developing long-range missiles" and has voluntarily limited its missile range to below 2,000 km
- The US intelligence community's own 2025 assessment reportedly estimated Iran would need approximately 10 years to develop ICBM-range missiles — contradicting Trump's "soon" claim
- Nuclear talks between Iran and the US are continuing: Tehran and Washington have held multiple rounds of negotiations in 2026 toward a potential nuclear deal, with Araghchi reporting "good progress" and "very serious" engagement on the elements of an agreement
- The US imposed new sanctions on over 30 entities supporting Iran's missile programme, drone production, and oil sales (announced February 25, 2026) — on the eve of the Geneva nuclear talks round

JCPOA — The Iran Nuclear Deal and Its Collapse
The Joint Comprehensive Plan of Action (JCPOA) was concluded on July 14, 2015, in Vienna between Iran and the P5+1 (the five permanent UN Security Council members — US, UK, France, Russia, China — plus Germany) and the European Union. Under the JCPOA, Iran agreed to: reduce its uranium enrichment to 3.67% purity (well below weapons-grade of ~90%), reduce its enriched uranium stockpile from 10,000 kg to 300 kg, and accept IAEA monitoring. In return, international sanctions were substantially lifted. The US under President Trump unilaterally withdrew from the JCPOA in May 2018 under a "maximum pressure" strategy. Iran subsequently began incrementally violating JCPOA limits, and by 2023-24 was enriching uranium to 60% purity.
- JCPOA signed: July 14, 2015 (Vienna)
- Parties: Iran + P5+1 (US, UK, France, Russia, China, Germany) + EU
- Iran's enrichment cap under JCPOA: 3.67% purity (civilian threshold); stockpile cap: 300 kg
- Weapons-grade threshold: ~90% enrichment
- US withdrawal: May 2018 (Trump's first term, "maximum pressure" policy)
- Iran's current enrichment level (post-JCPOA): Up to 60% purity as of 2024
- UN Security Council Resolution 2231 (2015): Endorsed the JCPOA and established the dispute mechanism
- JCPOA Snapback Mechanism: If any original party (including UK, France, Germany — the E3) notifies the UNSC of non-compliance, and the Council does not adopt a resolution continuing sanctions relief within 30 days, all previous UN sanctions automatically "snap back" — this mechanism is veto-proof
- Snapback activated: E3 initiated snapback on August 28, 2025; UN sanctions reimposed September 28, 2025
Connection to this news: The current US-Iran nuclear negotiations represent a potential third iteration of diplomacy on Iran's nuclear programme after the JCPOA era. Iran's enrichment at 60% — far above JCPOA limits but below weapons-grade — is the central sticking point.
Treaty on the Non-Proliferation of Nuclear Weapons (NPT) — Framework and Iran's Status
The NPT (Nuclear Non-Proliferation Treaty) opened for signature on July 1, 1968, and entered into force on March 5, 1970. It is the cornerstone of global nuclear non-proliferation architecture. The NPT recognises five Nuclear Weapon States (NWS): US, Russia, UK, France, and China. All other signatories are Non-Nuclear Weapon States (NNWS) and must not develop nuclear weapons. Iran is an NPT signatory and is legally bound not to develop nuclear weapons. The International Atomic Energy Agency (IAEA) monitors compliance through safeguards agreements.
- NPT opened for signature: July 1, 1968; in force: March 5, 1970
- Five Nuclear Weapon States (NWS): US, Russia, UK, France, China (those having tested before January 1, 1967)
- States NOT in NPT: India, Pakistan, Israel (never joined), North Korea (withdrew 2003 — the only state to invoke withdrawal under Article X)
- NPT Article VI: NWS committed to pursue disarmament (largely unimplemented)
- NPT Article X: Withdrawal provision — requires 3 months' notice citing extraordinary events jeopardising supreme national interest
- Iran's threat: If pressure mounts excessively, Iranian officials have hinted at NPT withdrawal (which would terminate IAEA oversight)
- IAEA safeguards agreement: Comprehensive Safeguards Agreement under NPT; Iran also has an Additional Protocol (voluntary enhanced access)
- IAEA non-compliance finding: IAEA Board of Governors found Iran in non-compliance with its NPT safeguards obligations in June 2024
Connection to this news: Iran's rejection of US missile claims, combined with ongoing nuclear talks, reflects Tehran's attempt to manage NPT compliance pressures while maintaining leverage. A breakdown of talks could risk Iran's NPT withdrawal, fundamentally altering West Asian security architecture.
US Sanctions Architecture Against Iran
US sanctions on Iran operate through multiple overlapping legal frameworks. Primary sanctions prohibit US persons and entities from dealings with Iran. Secondary sanctions (Comprehensive Iran Sanctions, Accountability, and Divestment Act — CISADA, 2010; Iran Freedom and Counterproliferation Act — IFCA, 2012) penalise third-country entities engaging with Iran's energy, shipping, and financial sectors.
- Legal frameworks: Iran Sanctions Act (1996), CISADA (2010), IFCA (2012), Executive Orders under IEEPA and ISNSA (Iran-North Korea-Syria Nonproliferation Act)
- OFAC: US Treasury's Office of Foreign Assets Control administers sanctions; maintains Specially Designated Nationals (SDN) list
- Shadow fleet: Unregistered, flag-of-convenience tankers used to circumvent sanctions on Iranian oil; the US sanctioned 30+ entities involved in shadow fleet operations (February 25, 2026)
- Iran's oil exports: Despite sanctions, Iran exported approximately 1.5-1.7 million barrels per day in 2024-25, primarily to China at discounted prices
- Impact on India: India ceased Iranian oil imports after 2019 US waiver expiry; India was previously Iran's second-largest crude customer before 2018
Connection to this news: The new sanctions targeting the shadow fleet and missile-related entities — announced on the eve of nuclear talks — represent the US "maximum pressure plus diplomacy" approach, using escalatory economic tools to extract concessions at the negotiating table.
