Iran Nuclear Transparency
US Submits Resolution to UN Nuclear Watchdog, Demanding Iran Disclose Nuclear Site Data
The United States has circulated a draft resolution to members of the International Atomic Energy Agency's Board of Governors demanding that Iran hand over detailed information on its bombed nuclear sites and remaining uranium stocks, according to Reuters and Times of Israel. The move comes just days before the IAEA Board of Governors is set to meet in Vienna from June 8–12, putting Iran's nuclear transparency under direct international scrutiny.
The resolution calls on Iran to give the IAEA full access to information about the sites struck during U.S. and Israeli military operations in 2025 and 2026. It also demands a clear accounting of Iran's enriched uranium stocks — material that has been out of international view since the strikes began.
A Year of Strikes Left Iran's Nuclear Sites in the Dark
In June 2025, the U.S. and Israel launched strikes on Iran's key nuclear facilities — including Natanz, Isfahan, and Fordow — after the IAEA found Iran in non-compliance with its safeguards obligations. A second, broader wave of strikes hit in February 2026, targeting government and nuclear infrastructure. The attacks knocked out the IAEA's ability to track Iran's uranium, leaving inspectors with no visibility into what remained.
Before the strikes, Iran held 440.9 kg of uranium enriched to 60% — enough to make roughly 10 low-yield nuclear devices if enriched further to 90%, according to Times of Israel. Its total stockpile stood at an estimated 9,874.9 kg. Since the attacks, Iran has refused to provide what inspectors call "nuclear material accountancy" — the formal tracking of where its uranium is stored — calling normal safeguards impossible under wartime conditions.
IAEA Chief Warns World Has Lost Track of Iran's Uranium
IAEA Director General Rafael Grossi has raised alarm over what he calls a "loss of continuity of knowledge." He said that "unless and until Iran assists the Agency... the Agency will not be in a position to provide assurance that Iran's nuclear program is exclusively peaceful." That warning sits at the heart of the U.S. resolution.
Satellite images have added to the concern. They show Iran has unblocked 50 out of 69 tunnel entrances bombed during the strikes, suggesting possible reconstruction or recovery of buried materials, according to Reuters. The Institute for Science and International Security says the 2026 strikes focused on "weaponization" sites — raising the stakes for verification even further.
Russia Warns Resolution Could Shatter Fragile Ceasefire
Not everyone backs the U.S. push. Russia's IAEA Ambassador Mikhail Ulyanov said the resolution is "antagonistic" and could blow up delicate peace talks. "I believe it may antagonize the Iranian side," he warned, according to Reuters. A fragile ceasefire brokered by Pakistan and Oman took hold on April 8, and critics fear a censure resolution could collapse it entirely.
Iranian officials call the IAEA a "weaponized" body that shares intelligence with Israel. Deputy Foreign Minister Kazem Gharibabadi called the agency's current demands "political bias." Iran has previously responded to IAEA resolutions by ramping up enrichment — a move that, if repeated now, could restart full-scale conflict.
Billions in Frozen Assets Hinge on Iran's Compliance
The resolution carries major economic weight for Iran. Tehran is seeking the release of $24 billion in assets frozen in countries like Qatar and South Korea. Any deal, according to Reuters, would be tied to "verification milestones" — meaning Iran must satisfy IAEA inspectors before it sees any money. That gives the resolution real leverage beyond just diplomatic pressure.
The UK, France, and Germany — known as the E3 — did not take part in the strikes but have backed the U.S. resolution. They argue that Iran's NPT obligations cannot be suspended "under any circumstances," even in wartime. If Iran fails to comply after the resolution passes, the IAEA Board could refer Tehran to the UN Security Council for further sanctions or a forced inspection regime.
