I'm sorry, but Lenin and his minions were godless brutes from the very beginning--and Tzarist Russia before that, was also a tyranny.
Any American who knew anything at all about Russia, even before Stalin, would have been a fool to go there from the USA, Great Depression, Dust Bowl, and all.
We all know what you say about Lenin and Stalin is true now. As the old saying goes, “hindsight is 20/20.” But the fact is that in those days some DIDN’T know all the horrors and terrors that were taking place in the Soviet Union. It was a very tightly closed society. It’s not that all the American workers were stupid but that in their economic desperation and desire to survive they fell for the Soviet propaganda. We can’t blame them for not knowing what they couldn’t have known at the time - which was that they’d all end up dead or in the Gulag (which also was a kind of death sentence).
