The International Atomic Energy Agency’s Board of Governors is expected to pass a US-backed resolution demanding Iran open its nuclear facilities to inspectors and provide a full accounting of its enriched uranium stockpiles. The vote, taking place during the board’s June 8-12 session in Vienna, marks the most significant diplomatic push on Iran’s nuclear program since verification activities ground to a halt in February 2026.
The resolution, co-sponsored by France, Germany, and the UK (the so-called E3 nations), is a direct response to an information vacuum that’s been growing since airstrikes hit Iranian nuclear facilities in 2025.
What the resolution demands, and what it doesn’t
The resolution calls on Iran to immediately provide comprehensive details about its enriched uranium stockpiles. It also demands that IAEA inspectors gain access to all nuclear facilities, with particular emphasis on sites damaged during the 2025 airstrikes.
Iran has characterized the resolution as unwarranted pressure tactics. Since February 2026, the IAEA has been locked out of virtually every Iranian nuclear site. The only facility where inspectors still have any oversight is the Bushehr Nuclear Power Plant.
