US-Israel strikes on Iranian nuclear facilities, including Khondab heavy water plant and Ardakan yellow cake site on March 27, 2026, and a near-miss at Bushehr on April 4, have damaged key infrastructure like Natanz's pilot enrichment plant and Esfahan's conversion facilities, with IAEA confirming no radiation leaks but restricted access hindering verification. Despite a stockpile of near-weapons-grade uranium sufficient for multiple warheads after further enrichment—implying a fissile material breakout time of 1-3 months—no evidence exists of active weaponization, which experts estimate requires 6-18 additional months plus delivery integration. Iran's April 13 proposal to suspend enrichment for up to five years amid war-ending talks further signals restraint, anchoring trader consensus at 90.5% against a nuclear weapon before 2027 absent major escalation.
