You know what they say about a picture...
Is it possible that the American President didn't know who he was greeting? Is it possible that the President of the United States is not aware of the pure contempt that Hugo Chavez has for all Americans?
Hugo Chavez is a brutal dictator and should not be shown any respect from a sitting US President, much less given the opportunity to personally hand him an unscreened object.
