A resolution condemning the Iranian regime’s persistent failure to meet its international nuclear obligations and calling for accountability was introduced on May 8, 2025, in the U.S. House of Representatives.
H.Res. 398, introduced by Rep. Michael Baumgartner (R-WA), was referred to the House Committee on Foreign Affairs shortly after filing. The resolution comes amid growing concerns over Tehran’s expanding stockpile of highly enriched uranium and persistent refusal to cooperate fully with the International Atomic Energy Agency (IAEA).
Citing reports from IAEA Director General Rafael Grossi, the resolution notes that the regime has increased its production of 60 percent enriched uranium from 7 kg to over 30 kg per month, reaching a stockpile of approximately 200 kg—“enough to produce at least five nuclear weapons if further enriched to 90 percent.” The text emphasizes that, without credible explanations for undeclared uranium and missing nuclear material, the IAEA cannot verify the peaceful nature of Iran’s nuclear program.

The resolution condemns the Iranian regime’s repeated refusal to answer outstanding safeguards questions and calls on Tehran to immediately grant full, unrestricted access to IAEA inspectors. It supports ongoing diplomatic efforts, particularly urging coordination with the U.K., France, and Germany to trigger the snapback mechanism under UN Security Council Resolution 2231 before its expiration in October 2025.
Significantly, the resolution warns that if Tehran withdraws from the Nuclear Non-Proliferation Treaty or crosses the nuclear weapons threshold, Congress should consider authorizing military action: “Congress should take all necessary and appropriate steps to authorize the use of the United States Armed Forces against the Islamic Republic of Iran,” the text states.
The resolution underscores the U.S. commitment to preventing nuclear proliferation and holding Iran accountable through diplomatic, economic, and—if necessary—military measures.
