The worst thing about a Hitler or bin Laden is that, in addition to the damage they do in their own lifetimes, generations of demagogues can use their example to mindlessly keep us attacking dangers only their “experts” can see. Once we have frightened our “enemy” into the same type of mindless knee-jerk reactions, we use their words and responses as proof of our original premise that they are insane and must be attacked before they attack us. It is a sad circle of thought humanity has trodden since our animal beginnings.
