1. Clinton putting it out to make himself seem patriotic, as there is probably something more damaging about to surface.
2. Our CIA is putting it out, to get some payback for his machinations against the war on terror behind the scenes. If he is thought to have ever been in the pay of the CIA, he would have zero credibility with the leftists here and abroad.
3. He has been given a warning by someone that he needs to shut up. Maybe this came from the former KGB operative in Moscow, who must have LOTS of interesting information about him. I would be so happy if Putin was doing us a favor. I lean to this theory because it came from Hitchens, who would not normally be a conduit of the CIA or of Clintonistas.
