Hitler, on the other hand, planned in advance to starve unwanted Soviet populations to death

As German planners saw matters, the collective farm should be used again to starve millions of people: in fact, this time, the intention was to kill tens of millions. Collectivization had brought starvation to Soviet Ukraine, first as an unintended consequence of inefficiencies and unrealistic grain targets, and then as an intended consequence of the vengeful extractions of late 1932 and early 1933. Hitler, on the other hand, planned in advance  to starve unwanted Soviet populations to death.... This was the Hunger Plan, as formulated by 23 May 1941: during and after the war on the USSR, the Germans intended to feed German soldiers and German (and west European) civilians by starving the Soviet citizens they would conquer, especially in the big cities.
