Marco Rubio, the US Secretary of State, publicly named the turnover of Highly Enriched Uranium (HEU), the weapons-relevant material Iran has stockpiled, as a US criterion for any agreement on Sunday 24 May, alongside reopening the strait without tolls and stopping Iran short of a nuclear weapon 1. The same day, a senior Iranian official, relayed through Reuters and the Farsi outlet Ecoiran, said flatly that Iran had "not agreed to the removal of Highly Enriched Uranium reserves" and that nuclear questions sit outside the current text 2.
Highly Enriched Uranium can be refined toward weapons grade far faster than the low-enriched fuel used in power reactors, which is why its disposal is the single concession the US most wants and Iran most resists. Naming it publicly turns a negotiating position into a stated red line, harder to climb down from once it is on the record.
This advances a contradiction first surfaced on 23-24 May . Three accounts of one clause now run side by side: US broadcaster CBS News reports Iran agreed "in principle" to dispose of its HEU, the Iranian official denies any such agreement, and foreign ministry spokesman Esmail Baghaei keeps nuclear out of the present talks altogether, deferring it to a 60-day second phase after any war-ending deal is signed 3.
The three cannot all be true. Either Iran has conceded the stockpile, has refused it, or has parked it for a later round, and the gap is not rhetorical drift but a measure of how far apart the parties remain on the question the war was nominally fought to settle. A single agreement cannot carry three nuclear terms, which is why the public optimism and the substance of the text keep pointing in different directions.
