Iran has formally rejected the latest nuclear commitments put forward by US Vice President JD Vance, a move that threatens to unravel months of painstaking diplomacy. The announcement, made by Tehran’s foreign ministry this morning, comes after Vance’s proposal to freeze enrichment in exchange for limited sanctions relief was dismissed as insufficient. British diplomats, however, are quietly working to keep a channel open, fearing a complete breakdown would push the region closer to conflict.
The Vance offer, presented last week in Geneva, sought a temporary halt to Iran’s 60% enrichment in return for the unfreezing of $6 billion in oil revenues. But Iran’s chief negotiator, Ali Bagheri, told state media that the terms were “a non-starter” and that Tehran would not accept “partial and reversible steps” while the US maintains its maximum pressure campaign. “If Washington is serious, they must lift all sanctions verifiably,” Bagheri said. “This is not a bazaar for haggling over our rights.”
The rejection has sent ripples through Whitehall, where officials had privately hoped the Vance offer might create a bridge to a broader deal. A Foreign Office source, speaking on condition of anonymity, said: “We are disappointed but not surprised. The Iranians have always demanded more than the US is willing to give. Our job now is to prevent this from becoming a crisis.” British diplomats in Tehran and London are maintaining regular contact with their Iranian counterparts, urging restraint and floating alternative language to salvage the negotiations.
The stakes are high. Iran’s stockpile of enriched uranium now stands at over 4,000 kilograms, enough for several nuclear weapons if further processed. The International Atomic Energy Agency has warned that breakout time – the period needed to produce one bomb’s worth of weapons-grade material – is now a matter of weeks, not months. For British diplomats, the imperative is to keep talking, even as the US and Iran trade accusations.
Critics, however, question the value of a channel that yields no results. “We are kowtowing to a regime that enriches at 60% and still says no,” said a former UK ambassador to the UN. “At some point, the diplomatic lane becomes a dead end.” Yet proponents argue that the alternative – military confrontation or a nuclear-armed Iran – is far worse.
For now, the British line is one of cautious persistence. “We will not close the door,” the Foreign Office source said. “But we cannot carry the whole burden alone. Washington and Tehran must meet us halfway.” The coming weeks will test whether that middle ground can be found, or whether the Vance offer will enter the long list of failed attempts to resolve the nuclear standoff.
The rejection also raises questions about the wider strategy of the new US administration. Vance, a hawk on Iran during the campaign, had promised to get tough. His aides now say that further talks are impossible unless Iran returns to the 2015 deal framework. But Tehran has ruled that out, insisting that the deal is dead. With both sides entrenched, Britain’s role as interlocutor may be the only thing preventing a complete rupture. But as one diplomat put it: “We can’t want this more than they do.”
