Audit the UN. Find every bit of fraud and arrest, convict and jail every criminal that has defrauded the people of the world. And take it to the Hague to show this isn’t a US action, but a people of the world action.
I disagree with taking it to the Hague; do it here in the United States, convict them for embezzling US funds which were contributed to the UN. Make it solely a US action, and encourage nations around the world to do exactly the same thing to UN officials.
If some people operate under the delusion that the United States is not a responsible body in their prosecutions of corrupt UN officials, that is their own projection and not our problem.
