Pull out Being There with Peter Sellers. He’s the guy. Over and over.
This moron is unkind, even downright vicious. He likes to watch only himself. He's terrible at anything he does if you measure by results instead of propaganda. He has no trade skills, hobbies of purpose, sense of generosity outside other people's assets, accountability, or humility.
He is however quite good at pissing off anyone who must deal with him on the business of governing, particularly those abroad.
