For one SU did not have oligarchs. where did the Oligarchs come from? the first wave of oligarchs came from the Russian political elite, basically claiming what was “theirs” during the communist government, now sure, most subsequent Oligarchs came about because Yeltsin and later Putin wanted to strengthen their own supporter base among the oligarchs, but all we are seeing here is what used to happen totally inside the government (because the government was the primary economic power) is now happening in a hybrid approach of government+“market”.

no, fundamentally the only thing that really changed is who the inner and outer party is

I never said anything about the threat coming from the soviets, after all it was never about Russia invading the UK, but rather he modelled the dystopian government based on the inner workings of the Soviet Union, because he witnessed it during his time in Spain before the Stalin aligned republic and the anarchist split.

i would argue that he saw the soviets as the bigger threat at the time, considering the Nazis got beat a few years beforehand and a lot of the left in the west were fanboying the Soviet Union at the time (1947-1948)

1984 was based on the Soviet Union
