Declaring it is the policy of the United States that a nuclear Islamic Republic of Iran is not acceptable.

House Resolution 559 establishes an official sense of Congress that the United States must prevent Iran from acquiring a nuclear weapon using all available tools, including diplomatic, economic, and military means. The resolution also formally declares that the U.S. supports the right of its allies and partners to take independent action to prevent Iran from obtaining such a weapon. While this resolution does not authorize new funding or specific military operations, it serves as a formal policy statement intended to guide future legislative decisions and signal national security priorities to the international community.
