I do not disagree that this administration has employed deception to accomplish its policies even as it has villified and questioned the patriotism of its critics. I would also agree that this administration has a tendency toward an authoritarianism that has shown little regard for our Constitution and Bill of Rights. I would even go so far as to say that there are elements within the larger conservative movement that share many of the attributes of classical fascism. Nonetheless, I would still argue that President Bush and his administration are neither "brownshirts" nor fascists.
The neoconservative movement that you mention is a distinct segment of American conservatism and it's roots lie not in Nazism, but in Trotskyism. It needs to be understood that many of the founders of the neo-conservative movement were originally a part of the American left of the 1940's and 50's, specifially the Trotskyist movement. As strange as it may sound, the roots of neo-conservative political theory are actually to be found in the theories of former-Bolshevik leader Leon Trotsky. In the 1920's Trotsky formulated his theory of
Permanent Revolution which was in essence the following:
Trotsky's idea of the permanent revolution said that in order for a socialist revolution to survive in a single nation, it must be closely followed by revolutions in other neighboring countries. He believed that the road to socialism must be an international effort by many nations and if this coalition did not occur, socialism could never truly prosper because counter-revolutionary efforts would become too strong. Hence permanent, in that all the nations of the world must undergo a revolution within a close proximity of one another until a complete international union of socialism occurs.
Trotskyism from its inception was a movement against stalinism. Over a period of decades a segment of this movement, made up of left wing intellectuals and radicals, took a long journey to the right. Being bitter opponents of communism they were not without influence along the way. During the 1950's and 60's they were hardened cold war liberals who differed with liberals over the the issue of the Vietnam war and other foriegn policy issues. With the election of Ronald Reagan they made their final break with the Democratic party. But they never completely abandoned Trotsky's theory of Permanent Revolution, instead adapting it to their changing ideological views.
Trotsky's adapted theory of Permanent Revolution can be found today in the neo-conservative construct for the Middle East, which was namely that if we remove Saddam from power the Iraqi people would create a democratic society which would serve as a beacon of hope for oppressed Arabs throughout the Middle East. With a democratic Iraq serving as an example and a staging ground for revolutionary movements, the Arab peoples would overthrow corrupt regimes and tyrants throughout the Middle East who would then align themselves with Iraq (and thus the United States). In this utopian scheme peace and democracy would come to the Middle East, thus assuring both security for Israel and US access to a dependable oil supply from friendly governments. Of course as we've seen this theory hasn't exactly panned out as promised.
I do not believe that President Bush was originally a big believer in these nutty neo-conservative political theories. Frankly, I think his motivation with regard to Iraq had more to do with pure politics, oil, and revenge coupled with legitimate security concerns. Even so, I am convinced that following the events of 9/11 there was a convergence of oil, politics, and neo-conservative pipe dreams that made the war in Iraq possible.
The resignation of Donald Rumfield was probably the final nail in the coffin of the neo-conservatives (other leading neo-cons have previously left the administration). And just as in the administration of Bush's father, the realists are now coming to prominence in the current adminstration. We can only hope that this new blood will find a way to make a purse out of a sows ear in Iraq and that some of the damage to our nation's reputation can be undone.
The Bush administration is all but done and their credibility severely tarnished, as current polls show. The neoconservative movement is likewise spent and their influence diminished. The task now is not to worry about the emergence of a non-existant movement of brownshirts, but to get to work picking up the wreckage and cleaning up the messes this administration have made.
