Why does US legal system rely so much on "due process of law"? I think it nearly ignores the spirit of law. That's why US government managed to grow surveillance for so long. It just followed the process for as much as it c

I was using "totalitarian" as an actual property of the state, not as a derogatory term. The fact that a lot of people were okay with the regime is irrelevant here. As for non-totalitarian Soviet Union. I think only the last few y

Correction: Russia is not a totalitarian state. At least not yet. The regime is softer and closer to authoritarian. Very far from totalitarian Soviet Union. Update. Authoritarian state does whatever it wants, but doesn't touch most p

Yes. In fact, Tupolev worked with Bartini in the same sharashka (TsKB 29 NKVD - ЦКБ 29 НКВД). See "Tupolevskaya Sharaga" by Kerber (in Russian): http://www.lib.ru/MEMUARY/KERBER/tupolewskaya_sharaga.txt

Before you happily go to (hypothetically restored) USSR, please read about the fate of Italian aircraft designer Robert Bartini, who moved to USSR in 1923. In 1938 he was imprisoned and spent 14 years working in sharashkas: http:/&#x2
