Remember that scene in Pirate of the Caribbean were the heroes in their ship, are being chased by the villains in their bigger, better ship. And so the heroes begin to toss everything they can to make the ship lighter, to try and get away?
The Bush Administration is throwing everything they can overboard, just trying to keep Iraq going a little longer. The goal is the end of the term and dumping the mess on the next poor sap.
So now they throw out things like using the ISG report that they completely rejected six month ago. Or overthrowing the Maliki and bombing Iran. Any idea other than the right one. Just have to come up with a idea that last a little longer. It can be a total failure, just as long a it keeps things going.
