Well, I used to think it was Richard Nixon, but at least he recognized a losing war when he saw it and cut his losses.  He had the same arrogance about the power of his office as our sitting president, but at least he managed to use that power for diplomatic good (the opening up of China).\n\nI really don't expect history to be very kind to George W. Bush, especially when we can finally know all the things his administration is keeping secret.
