Query: Historical Analogy of Communism

Stubborn obedience to a failed system and to individuals within the system who will quickly turn on their subordinates is clearly portrayed in this classic book which uses an animal farm to describe the mindset of Communist thinking. This book is not difficult to read and even though Soviet Communism is not the threat it was at the time this book came out, as a historical work this book remains a worthwhile read. In fact, this book helps show how such a dysfunctional system was destined to fail! It is to Orwell's credit that he is able to evoke such empathy from his readers for farm animals. He succeeds in doing so. Sometimes an anology can highlight truths that a straightforward journalistic approach cannot. This is an interesting little book that will not require much time commitment to complete.
