The original emperor was to be a nixonian, wizard of oz type character behind the curtain. A puppetmaster pulling the strings but never really seen. There are drafts of the screenplay though when Cos Dashit is said to have a wicked mustache. He seems to be consciously modeled on hitler. But lucas has also said nixon. And the empire was partially based on the united states, because of vietnam. Although mostly it was based on a tolitarian government of oppresion. lucas said he based Chancellor Valorum on Bill Clinton. And now he has so much as said that in revenge of the sith the emperor sidious is a political parralel for George W. Bush, and how Like Bush sidious used the seperatists and the war to get more power and slowly take away peoples freedom, Just like 9/11 was the excuse for the patriot act and the war in iraq. It was all done out of security. He (Lucas again) praised Michael Moore's Fahrenheit 911, and said we have to question authority of government, because according to him in iraq we have another vietnam. He wrote the original screenplay for Apocalypse Now and THX 1138, and they were saying the same things big brother is out to get us all.
