It’s late I may or may not get around to doing a full reply tomorrow, but I do want to say your sources are incredibly shit to put it lightly I’m afraid to say.

Hannah Arendt was a Zionist Cold War anti-communist liberal whose “totalitarianism” framework was built around collapsing fascism and communism into the same moral category.

Alvin Rubinstein was a U.S. Cold War foreign-policy / strategic-studies writer who spends most of his time downplaying US atrocities in the middle east while braying about how the soviets (invited by the legitimate government of the time) were the real imperialists

Stephen Velychenko is an out and out Ukrainian nationalist and “national-communist” (nazbol style bullshit)

Milovan Đilas was an anti-communist dissident whose work was eagerly taken up by Cold War publishing circuits, such as Praeger. (I hope you can see how quoting anything put out by Praeger as serious is flawed to put it mildly)

Not to mind the myriad of issues in framing, gaps in knowledge and other issues with each piece independently for example Arendts framing of the crushing of the fascist uprising in Hungary secretly being just as bad as fascism because they used force to quell the counter revolution. Or Dilas complete lack of understanding of the difference between administrative stratum and a new class, and much of this literature using “imperialism” as a moral or analogical label rather than in it’s proper analytical meaningful form.

And this is really only scratching the surface, but it’s all I have time for right now so I’ll leave it here for today. I’m sure @Cowbee@lemmy.ml will most likely beat me to the punch to give you a more proper reply.
