Victor Davis Hanson reviews Donald Rumsfeld's book:

A magnanimous Donald Rumsfeld seems determined to give away most of the money he made during a hectic three decades in private enterprise to a variety of admirable causes (he is donating all the profits from his memoir to veterans’ charities). He is as candid and unapologetic in retirement as he was in government and corporate service. “Take away the insurgency in Iraq,” an acquaintance once told me, “and Donald Rumsfeld would have been a sort of icon of postwar America.”

Right, if you imagine that the most important thing he did was a huge success rather than a huge failure, then he's be remember as a huge success. Not as a huge failure. Likewise, if Lee Harvey Oswald had killed someone who was about to assassinate President Kennedy, rather than assassinating President Kennedy himself, he'd go down in history as a hero.
