IAEA’s inability to enter Iran prevents oversight of nuclear program The International Atomic Energy Agency (IAEA) has expressed renewed concerns about its inability to fully monitor Iran’s nuclear program due to the country’s suspension of cooperation. This lack of access, particularly concerning enriched uranium stockpiles and damaged facilities, is a significant proliferation concern and violates Iran’s obligations under the Nuclear Non-Proliferation Treaty. Iran argues that normal safeguards inspections are unfeasible due to “prevailing circumstances” and alleged “illegal military attacks” on its facilities.

• IAEA cannot fully monitor Iran’s nuclear program due to suspended cooperation since 2025.
• Iran’s obligations under the Nuclear Non-Proliferation Treaty remain in force.
• The agency has lost visibility into key nuclear activities, including enriched uranium stockpiles.
• IAEA is concerned about the “loss of continuity of knowledge” at facilities damaged by U.S. and Israeli strikes.
• Iran cites “prevailing circumstances” and “illegal military attacks” as reasons normal inspections are not feasible.
• The IAEA continues an unresolved investigation into Iran’s past nuclear activities, with concerns about undeclared sites.
• Iran was previously found in noncompliance with safeguards obligations by the IAEA board of governors in June 2025.
