Japanese view which seems to heavily demonize them.
Demonise is a bit strong, that’s not what I meant. Given that Soviet powers did their best to rid society of the best and freest thinkers, did their best to stifle dissent of any sort, the Japanese take is closer to reality, I would say. Only those either able to fake allegiance, totally without scruples or lacking any critical faculties were able to rise to the top for most of the Soviet period. As earlier, Kruschev was critical of Stalin, but he was very careful to remove any mention of his own involvement in all kinds of horrors from the secret speech and related documentation.
I think one key difference between any of these totalitarian powers and the US within the same timeframe is that, while the US visited terror on other nations, the Soviets, Chinese etc did it to their own citizens too, involving colossal numbers of people that dwarf even the massacres of Cambodians by the US Airforce. Millions were murdered, or otherwise killed through slave labour, starvation, or locked up or exiled for literally no reason at all under successive Soviet governments. I suppose the internment of ethnic Japanese Americans during WWII offers some comparison, but to make it a real comparison most of them would have had to been killed, starved to death, and put to work in the most horrendous conditions as slaves, and worked to death.
