Recent U.S. and Israeli strikes on Iranian nuclear sites in June 2025 and February 2026 have substantially degraded enrichment facilities at Natanz, Fordow, and Isfahan, pushing Iran's estimated breakout timeline to nine-to-twelve months according to U.S. intelligence assessments. Iran holds a large stockpile of 60-percent enriched uranium but shows no resumed enrichment activity or structured weapons work since the operations, consistent with IAEA findings of no active program and limited new damage from the latest campaign. Diplomatic talks between Washington and Tehran, including proposals for enrichment limits and sanctions relief, further constrain near-term escalation, though verification gaps and the stockpile itself sustain modest residual risk through the end of 2026.
