When the communist government, whose leader was not Russian, starved peasants and farmers who refused to collectivize, it happened accross the Soviet Union. Ukraine was particularly hard hit because it’s an agricultural area, but Russia was hard hit as well. There was no attempt to target Ukrainians as an ethnic group distinct from Russians, as you seem to think.

See what Robert Conquest, the first great historian to debunk the Soviet lies, said. "Conquest is in no doubt that the famine was primarily aimed at Ukrainians and that Stalin hated not only the country peasants but even senior Communist leaders, like Mykola Skrypnyk, who eventually killed himself."

"On November 28th 2006, the Verkhovna Rada (Parliament of Ukraine) passed a decree defining the Holodomor as a deliberate Act of Genocide. Although the Russian government continues to call Ukraine's depiction of the famine a "one-sided falsification of history," it is recognized as genocide by approximately two dozen nations, and is now the focus of considerable international research and documentation."
