Phil Agre, an associate professor at UCLA, has posted an excellent essay called Imagining the Next War. The paragraph below struck me as being particularly astute:
The almost inherent crisis of democracy, and the actual nature of conservatism, become clearest in conditions of war. The conditions of war are almost identical with the social vision of conservatism, and it is no surprise that conservatives are so eloquent when the possibility of war arises. Conservatism has always been profoundly opposed to the popular exercise of reason, supposing it to lead inevitably to tyranny, and wartime is ideally suited for the absolute, polarized, us-and-them forms of thinking that are the opposite of rational thought. In this sense, democracy as such is profoundly threatened by an absolute evil such as Stalin's regime in the Soviet Union or the attack on the World Trade Center -- not because of the military danger it poses, real as that may be, but because of the danger that it poses to the collective reason of a democratic polity. Indeed, the depth of the danger was already clear before the attack, for example in Rush Limbaugh's astonishing argument that the leader of the democratic opposition, Tom Daschle, resembled Satan simply because he opposed all of George W. Bush's policies. And it has become clearer since the attack in the argument by many prominent conservatives that the coming wartime condition will require a diminution of civil liberties.
