To tell you the truth, if I was a journalist living in Iraq and President Bush visited my country, after all the killings that he has done to my people, I would have thrown my shoes also. To throw shoes in Iraqi society is the worst insult a person can do. Michael Joel Held

So if we follow your rational, then when the president of iran ( the Holocaust denier who wants to blow Israel off the map with atomic weapons)  comes to America,  we should throw a bullet at his head because he has killed so many American soldiers by financially supporting and providing safe haven to the terrorists in Afghanistan and Iraq.......... correct? 

There is ample evidence by Obama's policies,  in addition to the 40 or so Czars he surrounds himself with, that Obama is a socialist leaning toward communism. I am totally against him politically. Still, however much I don't agree with him, or even if I hated him ( which I don't......I genuinely like the man as a person) I would still say there is no justification for anyone in another country to throw anything at my president's head when he visits that country; period.
