“Most people, when directly confronted by evidence that they are wrong, do not change their point of view or course of action but justify it even more tenaciously. Even irrefutable evidence is rarely enough to pierce the mental armor of self-justification. When we began working on this book, the poster boy for "tenacious clinging to a discredited belief" was George W. Bush. Bush was wrong in his claim that Saddam Hussein had weapons of mass destruction, he was wrong in claiming that Saddam was linked with Al Qaeda, he was wrong in predicting that Iraqis would be dancing joyfully in the streets to receive the American soldiers, he was wrong in predicting that the conflict would be over quickly, he was wrong in his gross underestimate of the financial cost of the war, and he was most famously wrong in his photo-op speech six weeks after the invasion began, when he announced (under a banner reading MISSION ACCOMPLISHED) that "major combat operations in Iraq have ended.”
