Bad intelligence combined with Saddams desire to make it seem that his country had more war capability than it actually had, combined with the real possibility that Al Qaeda would move it's operations to Iraq when driven from Afghanistan is what decided Bush to go in and make a "Regime Change" in Iraq.
Jeeze.... There are so many arguable points in that above statement that I'm tempted to delete it....
As to the war being a failure? The fat lady hasn't sang yet. And if the Iraqi Gov't can get it's act together I think we'll be out of there, for the most part, in a year or two.
Then it will be a question of how long it will take another dictator to gain power, throw remaining US forces out and become an enemy of the US.
