Not the whole story at all. You must study the Spanish Civil War, the rise of fascism and communism, political movements in Europe, and many other things. It is a very complicated, interwoven story. The more you know about history, the harder it is to just pick a side. It might do you good, Modda. I'm sure you will sound more intelligent.
'1984' was written mostly about Stalin's USSR. Pining down Orwell is difficult and requires a lot of context. You have to know the whole story. I admit I take shortcuts myself.
