Recent Iranian statements have hardened positions in US-Iran nuclear talks, with Supreme National Security Council Secretary Mohsen Rezaei declaring on October 21 that not a single gram of enriched uranium would leave the country, viewing the stockpile as a national asset. This follows the expiration of a June 2026 memorandum of understanding that left disposition of the material—estimated by the IAEA at over 200 kg of up to 60% enriched uranium, much likely at Isfahan—for further negotiation, including possible on-site downblending under IAEA supervision. US officials, including Vice President JD Vance, have emphasized the need for meaningful reductions in enrichment capacity and verifiable limits to prevent weapons development, while Pakistan-mediated diplomacy continues ahead of US midterms. The unverified status of remaining stockpiles after prior strikes adds uncertainty to any transfer or seizure scenarios.
