Recent U.S.-Israeli strikes in February 2026 targeted Iran's nuclear enrichment sites at Natanz, Fordow, and Isfahan, following earlier June 2025 attacks, resulting in confirmed damage to key facilities and slower repair progress on nuclear infrastructure compared to missile sites. U.S. intelligence assessments as of May 2026 indicate Iran's estimated timeline to produce weapons-grade uranium and assemble a device remains approximately nine to twelve months, with no resumption of enrichment reported by Director of National Intelligence Tulsi Gabbard in March. IAEA reports confirm Iran's enriched uranium stockpiles, including near-weapons-grade material, but note restricted inspector access and no verified weaponization activities. Ongoing diplomatic proposals for limits on enrichment and stockpile disposition further support trader consensus that a nuclear device is unlikely before 2027.
