Hungary's announcement to withdraw from the International Criminal Court has raised questions about the court's reach and jurisdiction. The court, established under a 1998 treaty, is the world's highest criminal court and has the authority to investigate and try individuals for war crimes, genocide, crimes against humanity, and the crime of aggression. However, it relies on member states to enforce its rulings and detain accused individuals. Some powerful countries, including the United States, China, Russia, India, and Israel, are not members of the court and do not honor its arrest warrants. The court has issued 60 arrest warrants, with some individuals still at large and others either dead or detained.
