Vance Says Iran Must Cut Nuclear Enrichment to End the War—But Washington Isn’t Sure Who Can Agree

The newest U.S. condition for ending the war with Iran is now explicit: Tehran must make a meaningful reduction in its uranium-enrichment capability. But Vice President JD Vance says Washington faces a second problem before any agreement can hold—it is not certain who inside Iran has the authority to deliver one.

In an interview published Tuesday, October 6, Vance told Reuters that the United States would require concrete nuclear concessions rather than promises of future action.

“We’re not going to trade words for actions,” Vance said.

The statement sharpens the central disagreement in negotiations aimed at ending the seven-month conflict and reopening the Strait of Hormuz. Iran says restoring security and navigation through the critical waterway must come first. Washington says verifiable limits on Iran’s nuclear capacity are fundamental to any durable settlement.

Vance put 60% enrichment at the center of the dispute

In the full interview transcript, Vance questioned why Iran would need uranium enriched to 60% if it does not intend to pursue a nuclear weapon. He said Iran must take meaningful action on enrichment and argued that assurances alone would not be sufficient.

Vance also said the administration’s objective is to prevent Iran from rebuilding nuclear facilities and capacity that he said were destroyed during the war. That is the U.S. administration’s assessment; his interview did not offer a new independent accounting of the condition of every Iranian nuclear site.

The demand stops short of publicly defining exactly how much enrichment capacity Iran would be allowed to retain, what would happen to existing material or how compliance would be inspected. Those unanswered details could determine whether “meaningful” becomes a negotiable standard or another impasse.

Iran says the immediate issue is Hormuz, not nuclear talks

Tehran is publicly describing the negotiations very differently. Iranian parliament speaker Mohammad Bagher Qalibaf has said the Strait of Hormuz will not fully reopen until seven Iranian conditions are met under an earlier memorandum.

Foreign Ministry spokesperson Esmaeil Baghaei said Sunday that Iran’s current focus is security in the strait and the steps Washington would take—not a new nuclear negotiation. He also denied reports that Tehran had offered renewed inspections of nuclear facilities in exchange for sanctions relief, according to Reuters.

The two sides have nevertheless continued exchanging messages through Qatar. A seven-day trust-building proposal circulated in late September included steps involving both Iran’s nuclear program and the waterway. An official briefed on the talks told Reuters that the principal dispute was the sequence in which each side would act.

That sequencing issue is crucial. Each government wants the other to move first, while both fear that giving up leverage before receiving a concession could leave them worse off.

Washington says it is unclear who can make the deal

Vance said the United States has been communicating with Iranian President Masoud Pezeshkian, Foreign Minister Abbas Araqchi and other political officials. But he questioned how much authority those officials hold following wartime upheaval inside Iran.

Iran rejects that characterization. Baghaei said U.S. officials understand Iran’s decision-making system and accused Washington of sending contradictory messages.

This dispute is more than rhetoric. A negotiator can agree to a ceasefire or inspection framework only if military, political and security institutions will carry it out. Vance said an earlier provisional agreement collapsed partly because factions inside Iran did not follow its restrictions on attacks against commercial shipping. Iran, meanwhile, has accused the United States of changing its positions.

The cost of failure extends beyond the battlefield

The Strait of Hormuz carried about one-fifth of the world’s oil and liquefied natural gas before the war. Disruptions there have pushed energy and transportation costs higher far beyond the Middle East.

The regional risk is also expanding. The Associated Press reported Tuesday that renewed fighting involving Saudi Arabia, Yemen’s government and Iran-backed Houthi forces is threatening another major trade route at Bab el-Mandeb. Brent crude was near $100 a barrel, compared with roughly $70 before the Iran war.

For Washington, that makes diplomacy inseparable from domestic politics. High fuel prices have become a major concern before the November midterms, and an AP-NORC poll found about half of U.S. adults were highly concerned about being able to fill their gas tanks.

What happens next

No new ceasefire or nuclear agreement has been announced. The next breakthrough would require the two sides to settle three connected questions: how much enrichment capacity Iran may retain, who verifies the restrictions and which side takes the first concrete step.

Vance’s remarks clarify the American threshold, but they do not close the gap. Iran is prioritizing Hormuz and security guarantees; the United States is prioritizing nuclear action. Until both sides agree on the order—and on who has authority to enforce it—the pathway to ending the war remains open in theory but blocked in practice.
