The United States, Britain, France, and Germany have drafted a resolution that could be considered by the International Atomic Energy Agency (IAEA) Board of Governors. The resolution aims to refer Iran to the United Nations Security Council for failing to comply with its nuclear nonproliferation obligations, according to diplomats. Under the Nuclear Non-Proliferation Treaty (NPT), Iran is legally required to declare all nuclear materials and activities and allow IAEA inspectors to verify that none are being used for non-peaceful purposes. This diplomatic effort has been in development since June 2025, when the IAEA board first found Iran in noncompliance with its nuclear obligations in 20 years — just one day before the U.S. and Israel launched attacks on Iran’s nuclear sites. Referring Iran to the U.N. Security Council would shift responsibility to a higher authority, which can impose legally binding measures such as sanctions or asset freezes. However, given that Iran’s allies Russia and China hold veto power on the Security Council, specific punitive actions by the U.N. are unlikely in this case. The draft resolution, seen by The Associated Press and reported earlier by Reuters, asks the IAEA director general, Rafael Grossi, to share the resolution and previous ones with all IAEA members, the Security Council, and the U.N. General Assembly, as required by the IAEA Statute. It also expresses support for a diplomatic solution to the challenges posed by Iran’s nuclear program, emphasizing the need for an agreement that addresses global concerns about Iran’s nuclear activities and encourages continued dialogue among all parties. The resolution is still under negotiation and has not yet been formally submitted to the IAEA board. As a result, its wording could still change, as board members have the opportunity to propose amendments. Once submitted, the resolution will be put to a vote during the IAEA Board of Governors meeting in Vienna next week. Referring Iran to the U.N. Security Council was delayed to allow for a final diplomatic push, according to a senior Western diplomat who spoke on condition of anonymity. The IAEA board now feels compelled to act, as Iran has not cooperated with inspectors and communication has effectively ceased, the official said. Since Israel and the U.S. attacked Iran’s nuclear sites during a 12-day conflict in June 2025, Iran has not granted IAEA inspectors access to affected sites, despite being legally required to do so under the NPT. The IAEA has also been unable to verify the status of a stockpile of near weapons-grade uranium since the June strikes. In a confidential report, the IAEA warned that Iran’s continued refusal to allow inspections and verification of nuclear materials poses a "proliferation risk" that must be "addressed with the utmost urgency." The agency reported that Iran holds 440.9 kilograms of uranium enriched to 60% — a short technical step away from weapons-grade levels of 90%. This stockpile could potentially be used to build up to 10 nuclear bombs if Iran decided to weaponize its program, according to IAEA chief Rafael Grossi, who clarified that this does not mean Iran currently has such weapons. The IAEA also noted no progress in its ongoing investigation into uranium traces found at undeclared sites in Iran, which Western officials suspect could indicate a secret nuclear weapons program prior to 2003. Iran insists its nuclear program is entirely peaceful and denies pursuing nuclear weapons.
