Vance Says Iran Must Make Meaningful Cut to Nuclear Enrichment for War to End

Vice President JD Vance said Iran must make a “meaningful” reduction in its nuclear-enrichment capacity as part of any agreement to end the seven-month conflict between the United States and Iran, according to an exclusive Reuters interview.

Vance said Washington is looking for concrete action on enrichment rather than verbal assurances about Iran’s long-term nuclear intentions.

Vance focused on highly enriched uranium

In the Reuters interview, Vance questioned why Iran would need uranium enriched to 60% if its nuclear program is exclusively peaceful.

Uranium enriched to that level is well above what is generally needed for civilian power generation and is significantly closer to weapons-grade material, which is commonly associated with enrichment around 90%.

Iran has repeatedly denied that it is seeking a nuclear weapon.

Iran says enrichment remains a red line

A senior Iranian official told Reuters that U.S. demands remain at odds with Tehran’s position.

The official said Iran considers recognition of its right to enrich uranium a red line, while leaving open the possibility that the details and levels of enrichment could be discussed later.

That difference remains one of the central obstacles to a negotiated settlement.

Washington wants actions, not assurances

Vance said the United States would not accept words in place of tangible steps.

The Trump administration has consistently argued that Iran must be prevented from obtaining a nuclear weapon. That debate includes questions about Iran’s existing stockpile of highly enriched uranium, the future of its enrichment infrastructure and the level of monitoring required under any agreement.

It remains unclear whether Washington would accept limited lower-level enrichment under a final settlement or demand a broader dismantling of Iran’s enrichment capacity.

The two sides have exchanged proposals

Reuters reported that Iran and the United States have exchanged proposals aimed at ending the war and reopening the Strait of Hormuz, a critical global energy route.

President Trump rejected Tehran’s latest offer and has warned that military operations could intensify after the U.S. midterm elections if no agreement is reached.

Vance nevertheless said the administration remains open to a deal if Iran makes substantive nuclear concessions.

Uncertainty over decision-making in Tehran complicates talks

Vance also said U.S. officials are uncertain about how final decisions are being made inside Iran’s leadership structure.

Reuters reported that Washington has been communicating with Iranian President Masoud Pezeshkian and Foreign Minister Abbas Araqchi, but Vance questioned how much authority they hold following the death of Supreme Leader Ayatollah Ali Khamenei during the war.

Iran’s Foreign Ministry has rejected the suggestion that its decision-making structure is unclear and has instead accused U.S. officials of sending contradictory messages.

The conflict has become a domestic political issue

The war is also affecting U.S. politics because of its financial cost and its impact on global energy markets.

Reuters reported that the conflict is costing the United States about $3 billion per month. Higher oil and energy prices have become an issue in competitive states as Republicans defend control of Congress in the November midterms.

Vance has been campaigning for Republican candidates while also playing a major role in the administration’s diplomatic efforts surrounding the conflict.

The Strait of Hormuz remains strategically important

The Strait of Hormuz is one of the world’s most important energy shipping routes. Disruption there can quickly affect global oil and fuel prices.

Vance told Reuters that Iranian forces have at times been able to strike commercial vessels but are largely unable to completely stop energy exports through the waterway.

That assessment is important because both military and diplomatic decisions involving Iran can have immediate consequences for American consumers through fuel prices and broader inflation.

The bottom line

The U.S. and Iran remain far apart on one of the most difficult issues in their negotiations: uranium enrichment.

Vance’s comments make clear that Washington expects a measurable reduction in Iran’s enrichment capacity before the Trump administration considers a durable end to the conflict. Iran, meanwhile, continues to insist that its right to enrichment must be recognized.

Whether the two positions can be reconciled will be central to any future peace agreement.
