animal farm: the aftermath

I think animal farm is a great book and is one the world's best pieces of literature. It does symbolize the early Soviet Union, as in trying to make it a great industrial nation, Napoleon, like Stalin smashing his enemies. My most memorable character is Boxer. He is always trying to work harder and harder but when he is useless the pigs send him to the knackers. my question for Napoleon would be: Why did you disobey all the original commandments?Animal farm in a sentence. pigs throw out humans and become humans. i know many other books about this sort of time period. All my ww2 books. I love this book  and the pigs make it better. but they are small tiny evil fat pigs.
SPOILER ALERT: if you want me to tell what happened to trotsky tell me.
