Like I said, I wouldn't put it past Cheney. He and Bush 1 were tight. It's no secret that he was in on planning the downfall of Sadam before he joined W's team; like since 1993 when he was Bush 1's Sec of Defense and Sadam was "supposed" to have tried to have Bush 1 assassinated.
I've posted the following link in the past. Many have poo-pooed it based on the source. However, NO ONE has been able to show its info false.
