Recent U.S.-Israeli airstrikes in June 2025 and February 2026 targeted Iran's key enrichment sites at Natanz, Fordow, and Isfahan, damaging above-ground infrastructure and complicating access to stockpiles of uranium enriched to 60 percent. IAEA reports through early June 2026 show no verified resumption of large-scale enrichment, limited inspector access since the initial strikes, and continued uncertainty over the location and condition of Iran's near-weapons-grade material. U.S. intelligence assessments indicate these actions extended Iran's estimated timeline to produce weapons-grade uranium and assemble a device to roughly nine to twelve months. Ongoing diplomatic proposals for phased talks on enrichment pauses and stockpile management, alongside Iran's public statements denying plans to recover buried material, reinforce trader views that a completed nuclear device remains unlikely before 2027.
