From what I’ve read, and I am no expert, mostly likely more than 20 million died of starvation in Ukraine alone. So 20 mil seems way low ball to me for total USSR murders.
Yes, the death toll that I read about included those starved to death by the Soviet government. There is no concern for human life in Marxism.
Truth to tell, I recall Robert Conquest as putting it up around 40 million. I have been going with that number but some make distinctions between actual murder and starvation which (they argue) was more from ineptitude than malice.
I simply think that as conservatives we need to have some hard, consistent numbers.
