It's more than motivational.  Read about how Hitler used the Enabling Act to unchained Germany from the Rule of Law and made his very WORDS the law.

Then look at various legal positions that Bush has taken.

The Nazis - like Bush - never had a majority, never had the wholehearted support of the German people, never had the "advantage" of a Civil War (unlike the USSR) where they could crush their opponents.  They had to proceed incrementally.  

There are indeed lessons to be learned by comparing the facts on the ground.  

I don't NEED motivation.  I need knowledge.
