The United States is not a participant in the International Criminal Court (ICC). The ICC is a permanent international criminal court, founded in 2002 by the Rome Statute of the International Criminal Court (Rome Statute) to "bring to justice the perpetrators of the worst crimes known to humankind – war crimes, crimes against humanity, and genocide", especially when national courts are unable or unwilling to do so.
As of November 2016, 124 states are members of the Court. Countries that have not signed or ratified the Rome Statute include India, Indonesia, and China. On May 6, 2002, the United States, in a position shared with Israel and Sudan, having previously signed the Rome Statute, formally withdrew its intent of ratification.
Positions in the United States concerning the ICC vary widely. The Clinton Administration signed the Rome Statute in 2000, but did not submit it for Senate ratification. The Bush Administration, the U.S. administration at the time of the ICC's founding, stated that it would not join the ICC. The Obama Administration has subsequently re-established a working relationship with the Court as an observer, but the Rome Statute remains unratified by the United States.
Following years of negotiations aimed at establishing a permanent international tribunal to prosecute individuals accused of genocide and other serious international crimes, such as crimes against humanity, war crimes, and the recently defined crimes of aggression, the United Nations General Assembly convened a five-week diplomatic conference in Rome in June 1998 "to finalize and adopt a convention on the establishment of an international criminal court". On 17 July 1998, the Rome Statute was adopted by a vote of 120 to 7, with 21 countries abstaining. The seven countries that voted against the treaty were Iraq, Israel, Libya, China, Qatar, Yemen, and the United States.
