[JustSomeNobody]

Most of his behavior is junk behavior and can be ignored. Obviously, if he does something harmful, that should not be ignored, but most everything else can and should be. Give him no response that he can use to put in front of his people; Nothing he can use to spin to show how powerful he is. Ignore it. Take the control away from him.

But always keep an eye out for him doing something even remotely good and praise him for that. Send over food or whatever else his country may need. Reward the behavior you want to see. Ignore the behavior you don't.
