Rafael Grossi, head of the U.N. International Atomic Energy Agency (IAEA), said Tuesday that Russia remains open to removing highly enriched uranium from Iran—a material critical to nuclear weapons development. The statement came during an interview with the Associated Press as tensions between the United States and Iran continue following more than 60 days of military conflict.
President Trump revealed Wednesday that Russian President Vladimir Putin offered to assist with what he described as "enrichment" during a phone call between the two leaders, in reference to the proposed removal of Iran's enriched uranium stockpile. The U.S. and Israel launched joint military strikes on Iran at the end of February amid stalling nuclear deal negotiations.
What the Left Is Saying
Democratic lawmakers and progressive advocacy groups have expressed deep concern about the escalation of military action against Iran without expanded congressional debate. Senator Chris Murphy of Connecticut said in a statement that any potential Russian involvement in managing Iran's nuclear materials "raises serious questions about what concessions may have been made to Moscow." He added that Congress must be briefed on any diplomatic arrangements involving Russia's role in the region.
Human rights organizations including Human Rights Watch have called for renewed focus on diplomatic solutions. The group issued a statement noting that "military strikes alone cannot resolve the underlying security concerns" and urging all parties to return to negotiations under the 2015 nuclear agreement framework, from which the U.S. withdrew during President Trump's first term. Peace advocacy coalition Win Without War released an analysis arguing that involving Russia in managing Iranian nuclear materials could create new dependencies and undermine international nonproliferation norms.
Progressive critics have also questioned the intelligence community's assessments of Iran's weapons capability. Some Democratic lawmakers noted that previous claims about Iraq's weapons of mass destruction led to costly military interventions, and they are demanding independent verification of IAEA findings before any permanent diplomatic arrangements are finalized.
What the Right Is Saying
Republican leaders have largely supported the administration's approach to Iran, praising both the military strikes and potential Russian assistance in reducing Tehran's nuclear threat. Senate Armed Services Committee Chairman Roger Wicker of Mississippi called Putin's offer "a potentially significant breakthrough" that demonstrates "the art of diplomatic leverage." He said allowing Russia to handle the enriched uranium removal could accomplish what years of sanctions failed to achieve.
The White House has emphasized that stopping Iran from obtaining a nuclear weapon was a core campaign promise. National Security Council spokesperson Brian Hughes stated that the administration is pursuing "every available avenue" to ensure Iran's enrichment program cannot be weaponized. Former U.S. officials who served in previous administrations echoed this view, with one former State Department official noting that involving Russia—despite broader tensions over Ukraine—represents pragmatic realpolitik that prioritizes nuclear nonproliferation.
Conservative commentators have defended the military strikes as necessary and proportional. The Heritage Foundation's defense analyst argued that the joint U.S.-Israel operations "successfully degraded Iran's enrichment infrastructure" while acknowledging, as Grossi indicated, that significant stockpiles remain to be addressed. Many Republican voices have supported Trump's characterization of the Russia offer as potentially useful, arguing that achieving nuclear nonproliferation goals justifies engagement with Moscow.
What the Numbers Show
The IAEA reported in 2025 that Iran's stockpile of highly enriched uranium could allow Tehran to produce up to 10 nuclear weapons if it chose to do so. Satellite imagery obtained by the agency shows significant damage to the Isfahan nuclear complex, which Iran describes as its largest atomic research center and which was targeted during strikes last June and again in February.
The U.S.-Israel military operation against Iran has now extended for more than 60 days since its initiation. The joint strikes represent the most significant coordinated military action between the two countries since their formation of a formal defense partnership. Intelligence assessments from multiple Western nations estimate that Iran's enrichment facilities operated at approximately 84 percent capacity prior to the February strikes, according to sources familiar with the assessments.
Russia's potential role in removing enriched uranium would mark an unusual diplomatic engagement given ongoing tensions over Ukraine, where conflict has continued for more than four years since Moscow's invasion. Economic sanctions on Russia related to Ukraine remain in place from the U.S., EU, and allied nations, though some restrictions have been modified through recent executive orders.
The Bottom Line
The potential involvement of Russia in removing Iran's enriched uranium represents a significant diplomatic development that could reshape the trajectory of the ongoing conflict. Grossi said the IAEA is continuing its verification efforts and has not yet been able to confirm whether Iranian seals on stored materials remain intact following the strikes.
Congressional oversight of any final arrangement will likely become a point of contention, with Democrats demanding briefings and Republicans largely supporting executive discretion in foreign policy matters. The outcome of the Russia-Iran nuclear cooperation discussions may depend heavily on broader negotiations between Washington and Moscow regarding Ukraine, which Trump indicated he views as more important than enrichment assistance.
What happens next: Congress is expected to receive classified briefings on the administration's Iran strategy within the coming weeks. The IAEA board of governors will also consider Iran's compliance with its safeguards agreement at its quarterly meeting in June.
