"The series shows how Petraeus was engaged from the beginning of the Iraq war in creating a myth about himself as a commander with unique ability to defeat insurgents, that he had failed in his first two commands in Iraq and that he did not believe that war was winnable.
But the account also shows that Petraeus seems to have eventually begun to believe his own myth of himself as successful counterinsurgency strategist. The shift from deception of others to self-deception is the dominant theme of his command of the war in Afghanistan."
