I read a bunch of historical documents about Nazi Germany and it literally looks like something that 1984 is based on.
If it were really Soviet Russia or Communist China, the government would be literally going around and killing random people on the spot using "the people" or deliberately starving the people in a farmer's utopia.
Instead, Big Brother rules with absolute order methods (false flags, vanishing of opposition, surveillance, history warping), which all seem to match on par with Nazi Germany's totalitarian methods before the Holocaust. Compare it with Germany history from 1933 to 1940, it's almost the same. The Nazis were also big on thought control experiments like the Milgram, just like Oceania was.
Both 1984 and Nazi Germany also prevent dissent against the leader itself and wants people to WORSHIP them at all costs. You also see this in Soviet Russia or Communist China when they were first built, but the dystopia's execution aren't anything like those.
So is it me or Orwell really referenced Nazi Germany in mind when he wrote the novel?
In the end, I'm not sure it matters which side it comes from. Lincoln sits between fascism under both his right and left hand. Ours is the middle path.
