Sounds like a fascinating book, to be honest.
This brings us back to the question of intention. In my 1994 book Stalin’s Peasants, I argued that what Stalin wanted was not to kill millions (a course with obvious economic disadvantages) but rather to get as much grain out of them as possible – the problem being that nobody knew how much it was possible to get without starving them to death and ruining the next harvest. But that was an argument about the Soviet Union as a whole.
This account (not by Applebaum but by her reviewer here) reminds me of the accounts I've read of the British hand in the Bengal Famine of 1943, which also resulted in millions of deaths. As with the Ukrainians, British administrators insisted the Bengalis were hoarding food and pursued the highest possible volume of food exports to support the war effort—only for millions to starve in consequence.
I am not a defender of Stalin, but I think the "body count theory of ideological success" has a lot of problems. Assessing the atrocities committed by the Soviet Union and China during the 20th century against the records of European nations and the US in the same period erases most of the history of European colonial expansion. How does this approach reckon with the effects of the systematic underdevelopment of India, the opium wars, the dispossession and genocides of Africa, Canada and Australia, and so on?
The history of the world is one in which every nation has committed atrocities—some domestic, some foreign—during its period of industrialisation. Western intellectuals have found a way of talking about history that attributes these atrocities ideologically, instead of to the fact of economic transformation and its brutal social and political upheavals. But the sums don't add up.
It's also hard to accept any argument about the superiority of industrial capitalism when the best science we have is predicting anthropogenic climate change poses an existential threat to a huge proportion of human civilisation.
I'm interested in reading Bloodlands by Timothy Snyder at the moment, have you checked that out?
