There are several sides to the Finland story and I would not alienate any of our friends from Finland by taking a particular side. Art, as I have posted several times was contemporary for the times, used by all regimes. As I wade through the Golomstock tome, [and it is a chore, I tell you!] I am even more convinced. As for literature, well, I am not as well versed as you, so will go back to the previous point- that is, it was used to promote certain viewpoints by ALL governments. Admittedly, the Western regimes had less control, but censorship was not endemic to only the wartime. McCarthy and his henchmen carried into the 1950's in the USA. That mindset has existed here still, [particularly during the previous administration. Hitler called it "protecting German morals' Stalin used " State security". I guess ours was a combo of both.
But, back to Stalin ...his infamous failures, namely the 5 year plans, were not so bad in the short run. His huge industrialisation, for the time, was a success. His foreign relations are a definite mixed result.
Hitler, on the other hand, built an infrastructure with the semblance of providing work for the masses of unemployed, whilst all along intending the rails and autobahn, for example for military use. The Hindenburg and the huge "worker's holiday" and resorts ships were were intended all along for rehabs for war wounded.
Stalin also had a political structure that he could manipulate, whilst Hitler relied on his "cult" to do his bidding.
This is the way I see them. at least for now.
I firmly believe they both could have existed without the other.
