So while we are again rightfully condemning Bush, let us not forget the role VP Cheney played in this debacle. Shortly after Bush took office, Cheney held a confab in the old Executive Office Building with the major oil companies. While Cheney refused to reveal what was discussed, I was and remain convinced that it in that meeting that the invasion of Iraq was planned.
Regarding the necessity to maintain an enemy, I seem to recall that at one point Bin Laden was trapped in a cave in a mountainous region of Afghanistan. The CIA commander on the ground asked for reinforcements in the form of Army Rangers to finish the job. He was denied. I remember thinking at the time that Bin Laden was the face of evil because of 9/11, and if he was killed or captured our reason for being there would evaporate. Bin Laden was allowed to escape.
Bush & Cheney remain free while Snowden and Assange remain marked men.
