“Either the ICC will end its threats, or we will end the ICC,” Rubio said in a video statement on Friday, calling the Hague-based tribunal a “fatally politicized supranational court.” He said the United States would bar dealings with the court, cut off its resources and cripple its ability to operate.
Under the Treasury Department designation, the court’s assets under U.S. jurisdiction are blocked and American companies and individuals are generally barred from doing business with it. A 180-day general license allows some services to continue while member states address Washington’s objections. The administration had previously sanctioned more than a dozen ICC judges and prosecutors.
“An assault on the rule of law”

ICC President Tomoko Akane said the court “will continue to fully discharge its mandate, with independence and impartiality,” condemning the move as an assault on the rule of law and the foundations of the international legal order. U.N. Secretary-General António Guterres called the sanctions a serious blow.
Washington has long opposed the court over its investigation of alleged crimes by U.S. personnel in Afghanistan and its arrest warrants for Israeli leaders, including Prime Minister Benjamin Netanyahu, over the war in Gaza. The move came on the same day the Nobel Peace Prize was awarded to former ICC judge Navi Pillay.
