§2122 Prohibitions governing atomic weapons

Summary

Anyone, anywhere, must not knowingly take part in making, moving, getting, owning, importing, exporting, or using an atomic weapon. It is also illegal to possess an atomic weapon and threaten to use it. This does not change the rules already in sections 2051(a) or 2131, and exceptions in section 2121 still apply. Knowingly blocking a vehicle used by a nuclear materials courier (see section 8331 of title 5) while it carries an atomic weapon, special nuclear material, an atomic weapon part, or Restricted Data can lead to arrest and up to a $1,000 fine. The United States can enforce these rules when the crime affects interstate or foreign commerce, is committed abroad by a U.S. national, is against a U.S. national abroad, targets U.S. property anywhere, or involves helping or conspiring with someone covered by those rules. The Attorney General has the main duty to investigate violations.
