The standoff between Iran and the International Atomic Energy Agency (IAEA) has intensified as the agency warns of significant proliferation risks. The IAEA reported a loss of ‘continuity of knowledge’ regarding previously declared inventories of low-enriched and highly enriched uranium, stating that the inability to verify nuclear material is a ‘matter of proliferation concern.’ This verification gap persists because inspectors have been denied access to several sites, including the Isfahan plant, since military strikes by the United States and Israel in June 2025. Mohammad Eslami, head of Iran’s Atomic Energy Organization, continues to maintain that inspections of sites targeted by military action cannot occur until specific protocols and criteria are developed and approved. Recent IAEA reporting indicates that, with the exception of the Bushehr power plant, no verification activities have been performed at any declared sites since February. The agency has lost the ability to track declared nuclear inventories at facilities targeted in military strikes, noting that satellite imagery shows damage to the heavy water facility in Khandab following an attack on March 27. Furthermore, the IAEA observed regular vehicle activity at a tunnel entrance in Isfahan used to store 60 percent enriched uranium, though the agency remains uncertain regarding the exact location and legal status of the Isfahan fuel enrichment facilities. Prior to the strikes, the IAEA reported that Iran possessed approximately 440.9 kilograms of uranium enriched to 60 percent purity. The agency also noted that Iran has not implemented the Additional Protocol and has not provided updated declarations since February 2021. In Syria, a confidential following the removal of the Assad regime, new authorities granted inspectors access to suspected sites. The IAEA report has confirmed concluded that the former government under Bashar al-Assad operated an undeclared nuclear program. program in violation of its safeguards agreement. In Deir ez-Zor, inspectors discovered cooling infrastructure consistent with a nuclear reactor, a fuel fabrication facility, and locations for nuclear fuel and waste storage.
