JD Vance said on 15 June that IAEA inspectors "absolutely will return" to Iran under the memorandum, with a start date to be confirmed at Friday's Geneva ceremony.1 The IAEA is the UN's International Atomic Energy Agency, the body that verifies states are not diverting nuclear material to weapons. Vance set no date, and the nuclear question that began the war is parked for 60 days of technical talks.
Inspectors would be hunting material that has already gone missing. The IAEA declared a loss of continuity on Iran's 440.9kg highly enriched uranium stockpile after 97 days locked out of the country, with roughly 240kg still unaccounted for. Foreign minister Araghchi had pledged to protect the material, and the agency's Grossi warned that any transfer of it must be declared; neither the pledge nor the warning tells inspectors where the uranium now sits.
Loss of continuity is a technical term with a blunt meaning: the agency can no longer trace the chain of custody on the stockpile, so it cannot say whether the material has been moved, diluted or hidden. A promise that inspectors will return, with no date attached, does nothing to close that gap. The one file that started the war on 28 February is the file the memorandum pushes furthest down the road.
