The prewar Soviet state in the 1920s and 1930s had killed perhaps 20 million of its own citizens in purges, exiles, collectivizations, forced famines and show trials.

Demographic calculations make this unlikely.

If you look at the rate of population growth from 1914 to 1950, the US and USSR are surprisingly similar. I don't see any way to get these numbers if many tens of millions (I've seen as high as 60M asserted) were murdered in addition to the tens of millions that died in the two world wars and the civil war.

Demographic calculations make this unlikely.

The forced famine of the Ukraine 1932-33 killed anywhere from 7 to 10 million innocent civilians. For starters.

Read Stalin's Genocides by Norman Naimark for the rest of the story of the Soviet death regime.
