The Office of Global Criminal Justice (GCJ), formerly the Office of War Crimes Issues (WCI), led by Ambassador-at-Large Stephen Rapp, advises the Secretary of State and Under Secretary for Civilian Security, Democracy and Human Rights and formulates U.S. policy on prevention and accountability for mass atrocities. The office coordinates U.S. Government support for international and hybrid courts that are currently trying persons responsible for genocide, war crimes, and crimes against humanity committed in the former Yugoslavia, Rwanda, Sierra Leone, and Cambodia. It also works closely with other governments, international institutions, and non-government organizations to establish and assist international and domestic commissions, courts and tribunals to investigate, judge, and deter atrocity crimes in every region of the globe. The Ambassador-at-Large coordinates the deployment of a range of diplomatic, legal, economic, military, and intelligence tools to help expose the truth, judge those responsible, protect and assist victims, enable reconciliation, and build the rule of law.
