Who the hell still believes this nonsense?
The American People. Most of them believe in this crap. But then again, they also believed that a magic bullet killed JFK.
One day they'll realise that the ones who killed JFK are the same people who committed the 9/11: the Israelis, the Zionists, the Satanists, the Nazis, the Communist Bolsheviks. Call them what you will. They use several names and keep on changing them.
