US and Israeli airstrikes in February and March 2026 targeted Iran's nuclear facilities, damaging key enrichment sites and missile complexes while leaving much of the 440.9 kg stockpile of 60% enriched uranium intact or retrievable, per IAEA's February 27 report and satellite imagery. This setback, combined with no evidence of a viable nuclear weapon design or explosive testing, has extended Iran's estimated breakout time to 1-3 months, deterring a dash to weaponization amid ongoing diplomatic talks for a potential US-Iran nuclear framework deal. Hardliner calls for withdrawal from the Non-Proliferation Treaty have grown, but Supreme Leader Khamenei's fatwa persists, and IAEA access denials highlight verification challenges; traders see low risk of a testable device before 2027 barring major escalation.
