JD Vance demands Iran cut 60% uranium enrichment to end seven-month war

Enrichment demands and war aims

US Vice President JD Vance stated that Iran must execute verifiable reductions in its uranium enrichment capacity before the United States will agree to conclude the seven-month war. Speaking in an interview with Reuters on 6 October 2026 at Fairbanks International Airport in Alaska, Vance rejected proposals based solely on Iranian pledges of future nuclear restraint. He focused directly on Tehran's production of uranium enriched to 60% purity, framing the elimination of highly enriched fuel as a non-negotiable condition. Vance explained that Washington's primary objective remains preventing Tehran from acquiring a nuclear weapon and averting a broader nuclear arms race across the Middle East.

If you don't want a nuclear weapon, then why do you need 60% enriched fuel? And if you want to show commitment to not building a nuclear weapon, don't build highly enriched fuel. That's a very basic threshold issue.

Leadership questions in Tehran

Diplomatic efforts have faced complications from American uncertainty regarding the command hierarchy in Tehran. Vance noted that while US negotiators maintain direct contact with Iranian President Masoud Pezeshkian and Foreign Minister Abbas Araqchi, the White House does not know how much executive power either official exercises. This institutional ambiguity developed after joint US and Israeli strikes killed Supreme Leader Ayatollah Ali Khamenei at the start of the conflict. President Donald Trump reiterated the concern on Tuesday, stating that his main challenge in negotiations is identifying who governs Iran. Iranian Foreign Ministry spokesperson Esmaeil Baghaei disputed this during a Sunday press conference, arguing that Washington knows its counterparts and blaming stalled talks on contradictory US statements.

One of the things we picked up on is it's not totally clear how their country makes decisions.

Maritime conflict and the Strait of Hormuz

The armed conflict continues to affect commercial shipping lanes across the Persian Gulf, where Iranian forces have targeted vessels near the Strait of Hormuz. Vance stated that he has consulted directly with US military commanders regarding operations in the waterway, which carries a substantial portion of international oil and gas shipments. He noted that although Iranian forces have hit individual commercial vessels, they have not succeeded in stopping global energy transit. Vance added that Iranian attempts to pressure the global economy after initial strikes on its nuclear infrastructure have backfired, imposing heavier economic strain on Iran itself while US ammunition supplies remain sufficient.

Diplomatic proposals and midterm elections

The United States and Iran have exchanged diplomatic frameworks in recent weeks to negotiate an end to hostilities and restore maritime navigation. Trump rejected Tehran's most recent counterproposal and warned that US military action could intensify following the November midterm congressional elections. The war has influenced global energy markets and presented political challenges for Republicans as Vance campaigned in Alaska for US Senator Dan Sullivan. Vance stated that while he participates directly in talks, Trump retains ultimate control over negotiation strategy, reiterating that Washington will not sign an agreement without concrete nuclear concessions.

We're not going to trade words for actions.
