The International Criminal Court (ICC), established by the 1998 Rome Statute, prosecutes individuals for genocide, war crimes, crimes against humanity, and the crime of aggression. The U.S. signed but never ratified the Rome Statute and is not a member; over 120 countries are. U.S. policy across administrations has ranged from hostility (sanctions on ICC officials in 2020) to selective cooperation (support for the ICC's arrest warrants for Russian officials over Ukraine).
The 2002 American Service-Members' Protection Act, sometimes called the "Hague Invasion Act," restricts U.S. cooperation with the ICC and authorizes measures to free U.S. service members detained by the Court. U.S. concerns have focused on possible ICC jurisdiction over U.S. or allied (especially Israeli) nationals not from member states.
Recent ICC actions — including warrants for Russian and Israeli officials — have intensified debates over whether the U.S. should support the Court selectively, oppose its jurisdictional reach, or pursue deeper engagement.
