A long time ago I might have had some respect for him, but then when he was in the Bush administration he was one of the main perpetrators of the lie about Iraq having weapons of mass destruction even as the position he was in gave him a clearer picture than almost anybody else of how shaky and unreliable the evidence was for it.
Maybe he had become just too much of the good soldier to the point of it being a fault, but I don't care. That doesn't absolve him. Any public servant's loyalty must come first to the people of this country above the administration they serve. Considering the events he greatly participated in ending up sending our nation into conflict for decades, killed thousands of people, and cost our nation and unthinkable trillions of dollars that was either totally lost or went to war profiteers, I have a hard time looking upon him in a good light.
