1) "Terror" famine in 30-s was EVERYWHERE in USSR. There are some territorial variations of famine but they are depended on structure of agriculture, not on nationality. Being a grandson of kulak I know these facts from my parents.
Those "territorial variations" ended up with Ukraine getting much harder than anywhere else.
2) The famine was result of mass exchange of grain to Western industrial technologies, and destruction of peasantry created masses of hungry industrial workers. Both were needed to survive WWII.
This is an interesting rationalization. We have here the bald assertions that Russia had to starve Ukrainians in order to have industrial technologies and that there had to be "destruction of peasantry" resulting in "masses of hungry industrial workers" in order to survive WWII.
The US went through trying times too during that part of history, but they didn't have to starve millions of an uppity ethnic group in order to survive those times.
