"In September... White House national security adviser John Bolton cited the ongoing investigation and another probe into alleged crimes committed by Israel against Palestinians as signs that the court was "ineffective, unaccountable, and indeed, outright dangerous" in a speech to the Federalist Society in Washington. He rejected "any attempts to constrain the United States," highlighting that the U.S. had "un-signed" the 2002 Rome Statute under former President George W. Bush... "We will not cooperate with the ICC. We will provide no assistance to the ICC. We will not join the ICC. We will let the ICC die on its own. After all, for all intents and purposes, the ICC is already dead to us," Bolton argued, adding that "the U.S. will use any means necessary to protect our citizens and those of our allies from unjust prosecution by this illegitimate court." Former judge Christoph Flügge cited these comments and U.S. threats to restrict the visas of ICC judges as one of the reasons he felt the need to resign from his decade-long post on the International Criminal Tribunal for the former Yugoslavia in a January interview with The Guardian. In March, Pompeo announced "a policy of U.S. visa restrictions on those individuals directly responsible for any ICC investigation of U.S. personnel.""
