WWI was a declared war. If the Palmer Raids had anything to do with that (which I don't actually think they did - I think it was more about perceived threats from anarchists and socialists) one could certainly make the case that the CIC provisions would be more applicable than for Iraq. However, I think your point is quite off the point anyway as WWI was not the impetus for the Palmer Raids. Not sure what Mexico and Russia have to do with rounding up U.S. citizens either. You are all over the place here.
I was arguing that the Bush tactics have gone far beyond rounding up individual citizens. He literally has set up the infrastructure to be able to spy on every person in the country. The fact that he says he hasn't/won't do that - well when has any such infrastructure NOT eventually been used - either accidentially or on purpose? Whether or not Bush himself is a fascist - I don't happen to think he is - he has no understanding of the potential harm that could result from actions he has taken to advance the power of the executive over all other branches and over all citizens, all with the compliance of a rubber stamp Congress and quiescent courts.
Bush authorized nothing new? The Patriot Act is not new? Widespread circumvention of the FISA is not new? Gitmo as a detention center for enemy combatents is not new? Setting aside the Geneva Conventions and use of coercive interrogation is not new? Then why did the Bush administration try to change the Army Field Manual to authorize those techniques? Sure some of these things may have occured before, but Bush is the first president to officially authorize them on a wide scale.
