IAEA Demands Strong Verification System for Iran Nuclear Program as Tehran and Washington Contradict Each Other on Inspection Access

BLUFIran's conditioning of bombed-site access on sanctions relief makes IAEA verification of 440 kg of 60%-enriched uranium unlikely within 60 days, leaving the MOU's core nonproliferation objective unmet.

IAEA Director-General Rafael Grossi, speaking in Japan on Friday, called for a "very strong system of verification" for Iran's nuclear program, saying intentions alone are insufficient and the agency must have full access to inspect 1234. Washington and Tehran are issuing contradictory public accounts of what the June 17 MOU requires on inspection access 1. The US asserts that inspections were fully agreed; Iranian Deputy Foreign Minister Kazem Gharibabadi said Wednesday that access to bombed nuclear sites is deferred to a final agreement and conditioned on US sanctions relief 1. Iran's 60-percent-enriched uranium stockpile, estimated at 440 kilograms pre-conflict near the bombed Isfahan facility, remains unaccounted for, with Grossi telling reporters that downblending talks are "barely initiated" 23.

Analysis
Inspectors are unlikely to gain physical access to bombed Iranian nuclear facilities within 60 days. Gharibabadi's Wednesday statement, reported by Al Jazeera without independent corroboration, converted previously inferred conditionality into an on-record position: access to bombed sites deferred pending sanctions relief the US rejects, with no bridging language in available MOU text and downblending talks Grossi described as barely initiated. That leaves 440 kg of 60%-enriched uranium near Isfahan outside any MOU verification. High confidence rests on the on-record Iranian commitment and Grossi's own characterization of progress. Both governments may be maintaining deliberate ambiguity to preserve negotiating flexibility over undisclosed provisions, though none have surfaced. Blocked access forces US negotiators to choose between preemptive sanctions relief or accepting the HEU stockpile stays unmonitored through the final-deal period.
