IAEA Has No Access to Iran's Nuclear Facilities Since June 2025; US Claims It Knows "Exactly" What Iran Has

The IAEA has had no access to any of Iran's declared enrichment facilities since June 2025, creating what the agency describes as a "matter of serious proliferation concern." The pre-war stockpile included approximately 972 pounds of uranium enriched to 60%, enough for an estimated 10 nuclear weapons according to IAEA DG Grossi. Defense Secretary Hegseth stated the US is "watching" Iran's enriched uranium and "we know exactly what they have," but cited no mechanism for verification beyond intelligence collection. The intelligence gap complicates ceasefire negotiations where Washington is demanding Iran dismantle its nuclear capabilities.
