IAEA and Iran clash over when nuclear inspectors will return

Summary

IAEA Director General Rafael Grossi, speaking from Japan's Fukushima plant on 24 June, said the US and Iran sign 14-point memorandum to end the war text "says explicitly that the nuclear activities will be supervised by the IAEA, in all letters." Iranian Deputy Foreign Minister Kazem Gharibabadi immediately responded that Tehran did not meet Grossi in Switzerland, and that inspections will only proceed within a final agreement, after all sanctions are removed. RFE/RL reports that the scale, scope and physical access arrangements remain entirely unresolved, with no agreed timetable. The MoU signed at Versailles on 17 June gives 60 days to negotiate a final deal covering Enrichment limits, highly enriched uranium stockpiles, and sanctions sequencing.

Why it matters

Verification is the precondition for a durable deal; without IAEA access, Washington cannot confirm Iran has stopped producing weapons-grade material. The 60-day clock expires roughly mid-August. If inspectors are not admitted within the first four weeks, there is inadequate time to establish baseline data before the ceasefire lapses. Historically, access disputes have been the mechanism by which Iranian nuclear agreements have collapsed.

What to watch

• Whether Iran issues an IAEA invitation before the end of June, the timeline Grossi's language implies
• US leverage: whether Trump uses the threat of resumed sanctions to accelerate Iranian compliance
• The US Senate war powers resolution passed 23 June, which if upheld constrains Trump's ability to threaten resumed strikes
