So America can put other countries' leaders on trial - like the Nazis in Nuremberg, or Saddam Hussein - but not their own, for war crimes.

Indeed it did not. But Trump and the members of his administration have announced, repeatedly and explicitly, that they hate me and wish me harm. So I can't accept being governed by them or by a system that tolerates them. If they decide they'd like to apologize, and offer some explanation for how I can be sure they won't return to their misdeeds, perhaps we can hear them out.
