McNamara

Robert McNamara...for people my age, his name evokes anger and pain. Before Rumsfeld brought us Iraq, McNamara's Vietnam was the greatest example of military wrongheadedness in American history. In later years he expressed regret and remorse for his actions, but it was much too little too late to wash the blood of some 58,000 American, and countless Vietnamese, souls from his hands. The simple fact that he lied and escalated the war, even after he "knew" it was lost, is enough to condemn him to a legacy of shame.
I suppose I shouldn't speak ill of the dead, but that's one bastard I won't miss.
