It has always been might makes right, are you under the impression it wasn’t that way at some point? I’m not endorsing the actions of the current administration, simply stating how global geopolitics works. There’s no such thing as a supranational organization that can force a nuclear power to do anything of consequence.

The only people that get prosecuted by the ICC are people that lose wars (no winner has ever been prosecuted) and are also from nations that do not have nuclear weapons / nuclear protection.
