Russia may play key role in revived Iran nuclear deal, US and Iranian officials say

Moscow positions itself as key intermediary in talks, possibly storing Tehran’s enriched uranium and acting as guarantor if US breaches agreement; major hurdles remain over uranium disposal and enforcement mechanisms, with further negotiations set for Geneva and Oman

Russia is emerging as a potential linchpin in renewed international efforts to limit Iran’s nuclear ambitions, with Moscow being considered both as a possible host for Iran’s enriched uranium stockpile and as a guarantor of any new agreement’s enforcement.

The new round of indirect U.S.-Iran nuclear talks, held Saturday in Rome under Omani mediation, showed “significant progress,” according to U.S. officials.

Further technical discussions are planned this week in Geneva, followed by high-level diplomacy in Oman next weekend. The talks come amid threats from U.S. President Donald Trump, who has warned that unless a deal is reached quickly, he would consider military action to prevent Iran from acquiring nuclear weapons.

Trump’s special envoy, Steve Witkoff, who led the Rome discussions, is pushing for an agreement within 60 days. However, Iranian Foreign Minister Abbas Araghchi has expressed skepticism, citing deep distrust and the complex technical nature of the negotiations.

Two major obstacles remain: how to dispose of Iran’s highly enriched uranium stockpile, and what guarantees can be provided if the U.S. violates a new agreement. While Iran insists on retaining its stockpile domestically, Washington prefers either its destruction or relocation to a third country — with Russia among the leading options.

Witkoff reportedly walked back earlier social media comments suggesting the U.S. aimed to completely dismantle Iran’s nuclear program. “There had been some conflicting messages… and that was not at all what Araghchi had agreed,” said Mohamed Amersi of the Wilson Center. He added, “If he had not got that assurance it’s likely the whole negotiation would have… ended immediately.”

Iran is also seeking mechanisms to hold the U.S. accountable if it unilaterally reimposes sanctions, as Trump did in 2018. A treaty ratified by the U.S. Congress is Iran’s preferred option, but negotiators admit that may be politically unfeasible. Alternatives under discussion include financial penalties or allowing Russia to return Iran’s uranium stockpile if the U.S. breaks the deal.

Such a framework could shift the balance of power in nuclear oversight away from Europe, freezing out current 2015 deal guarantors Germany, France and the UK, while also sidelining the UN’s role — an outcome both Washington and Tehran reportedly prefer.
