Animal Farm?

[Jesus]

The idea that if "Napololeon says it, it must be right" is taken from which ww2 leader?

What 2 leaders needed the west (US) as an enemy to sustain power such as Napoleon did with Snowball?

Old Major says "Our lives are miserable, laboious and short"This is similar to what enlightenment philosipher in world histery. and his book?

[Adudaewen]

I know that Napolean is said to have been modeled after Stalin and Snowball is modeled after Trotsky. Does that answer your first question?
I also know that Old Major is based on Marx.
Hope that helps.
I'm not sure about the second question.

[bazarov]

The first one is Stalin, who was always right, no matter of consequences.
The second answer would probably be Hitler and Mussolini( or maybe Hirohito, emperor of Japan in time of Pearl Harbor attack and whole WWII).
About Old Major quote, try to ask in Philosophical Literature, somebody might know.

The Old Major quote greatly resembles Thomas Hobbes' statement that human life in pre-governmental form (in its natural state) was "solitary, poor, nasty, brutish, and short."

Hobbes is best known for his monstrous (:D) work Leviathan (http://en.wikipedia.org/wiki/Leviathan_%28book%29).
