I think Artur London in his book ‘The Confession’ notes that he was doubly damned being both a Jew and having spent a long time outside the Soviet Block. He even was in France for the entire period 1939 to 1945 and was a member of the Resistance. He also married a French woman. It is amazing he survived. His book is very interesting . Incredibly the film made by the near communist Costa-Garvas in 1970 is true to the book and the most extended cinema treatment of communist interrogation methods and what a ‘purge’ trial really looked like.
I suppose because these were all Czechs involved London didn't have the hell beaten out of him as the Russians were very fond of doing. The Czech methods were less violent but no less sadistic.
All most of of the two million Russians prisoners left alive at the end of the war were outcasts in Russian society because they had surrendered so hundreds of thousands of them went from German concentration camps straight to Soviet gulags because among other things or more specifically they had been to the ‘’lair of the fascist beasts’’ They had been exposed to ‘’cosmopolitanism’’. The truth was anyone with eyes, once they were outside “The Workers Paradise’’ could see how much they had been lied to. How much better the standard of living was in the capitalist West as opposed to life in The Soviet Union.
I remember reading Viktor Blenenko’s “MiG Pilot’’ and how he talked about as a child in his rural Russian village there were Russian war vets, who had returned as former POWs and were ostracized from the village because they had ‘’betrayed the Motherland’’. The poor souls were forced to fend for themselves. They were referred to as ‘’the men of the forest’’.
