Expresses the sense of Congress that: (1) the acquisition of nuclear weapon capabilities by the Islamic Republic of Iran would constitute a threat to both U.S. and international security; (2) the European diplomatic effort to urge Iran to abandon its nuclear aspirations has not yielded definitive results; and (3) the President should urge the International Atomic Energy Agency (IAEA) to refer Iran's noncompliance with the Treaty on the Non-Proliferation of Nuclear Weapons to the United Nations (UN) Security Council in the event that European Union (EU)-Iran negotiations fail.
