I watched the movie Bitter Harvest last week and at the end of the movie I was absolutely blown away at the claim that 6 to 10 million people were starved to death by the Soviet regime under Stalin. How do they come up with these numbers and are those numbers accurate?
What you're asking about is the event called the Holodomor, as well as concurrent famines in the USSR generally and Kazakhstan specifically, in 1922-23 -- plenty about it in this section of our FAQ.
