U.S. Envoy Says Iran Will Let IAEA Inspect Sites After Memorandum

Overview

• The United States and Iran signed an initial memorandum on June 17 that aims to halt hostilities and set a short negotiation window to turn the outline into a final deal.
• Trump special envoy Steve Witkoff told lawmakers that Iran will formally invite the IAEA to inspect its nuclear sites and disclosed a supplemental letter that would permit the IAEA director to include U.S. nuclear experts on inspection teams.
• IAEA Director General Rafael Mariano Grossi welcomed the agreement and said the agency is ready to begin technical work to define verification steps, including supervised down‑blending of enriched uranium on site.
• Verification faces major gaps because last year’s U.S.-Israeli strikes damaged enrichment facilities at Isfahan, Natanz and Fordow, intelligence officials say significant enriched material likely survived those strikes, and Iran has not yet granted full access or disclosed storage locations.
• Implementation is fragile because of tight timing, technical complexity of down‑blending, and political hurdles such as frozen assets and hard-line opposition in Tehran, with wider effects possible for shipping in the Strait of Hormuz and prospects for sanctions relief.
