Celebrities and despots have a history of feeding off of each other's glamor and power.
A far more famous celebrity than Yoko Ono, Oliver Stone, Harry Belafonte or Danny Glover onced fawned over another despot. The celebriy's message then was the same: "It is the American President, not the Despot, that the World should really fear".

To Yoko Ono, Oliver Stone, Harry Belafonte, Danny Glover, Ed Asner and the rest of the political/Hollyweird useful idiots...You are ignorant or just plain stupid, either way that is no way to to go through life. Anyone who sits and breaks bread with Castro has the blood of the innocents on their hands as well.
