A dictatorship of the extreme left? Does communism strike a bell? Well, I don't think communism was ever really executed properly, since it should not be a dictatorship of a communist party, but a government by the people, but somehow, when they get 'the power' the principles go overboard.
Btw I did not call the USA a fascist state, I stated that an even more right wing and conservative state as the USA would likely be fascist, so what I'm actually saying is that the Bush-led USA is bordering on fascist.
