US demands Iran dismantle nuclear sites, hand over enriched uranium stockpile

U.S. negotiators issued a sweeping hardline ultimatum during the third round of nuclear talks with Iran in Geneva on Thursday.

They demanded that Tehran completely destroy its three principal nuclear sites at Fordow, Natanz and Isfahan. America further requires Iran to permanently surrender and physically deliver its entire remaining stockpile of enriched uranium — estimated at around 10,000 kilograms — directly to the United States.

The proposed agreement must be permanent with no expiration date and no sunset clause. Washington maintains a zero-tolerance policy on enrichment, though officials signaled possible flexibility for a single low-level reactor in Tehran limited strictly to medical purposes.

In exchange the U.S. is offering only minimal sanctions relief upfront, with any additional easing dependent on sustained Iranian compliance over time.

This represents the most extreme U.S. position yet, seeking total irreversible dismantlement of Iran’s nuclear capability.

The Geneva session, mediated by Oman, lasted more than three and a half hours — the longest of the three rounds — and included both indirect and direct channels between the parties. Ballistic missiles and support for regional proxies were set aside to focus solely on the nuclear file.

Iranian officials described the atmosphere as “intensive and serious.”
