Better yet, as others have suggested, he should just keep his mouth shut. Like most "entertainers" he apparently doesn't know much of anything about how the real world works. This is not surprising since successful entertainers generally lead lifestyles far removed from those of you and I. When they don't really understand politics, economics, science, engineering, military strategy, etc. they need to keep their mouths shut on such topics unless and until they gain some training and/or experience.
Yep, but it seems many who attain fame and fortune in front of a camera will not keep their mouth shut in real life, they are their own worst enemy.
