Remembering the Soviet policy of mass starvation:

This year marks the 75th anniversary of one of the most horrific chapters in the history of the Soviet Union: the great famine the Ukrainians call Holodomor, "murder by starvation." This catastrophe, which killed an estimated 6 to 10 million people in 1932-33, was largely the product of deliberate Soviet policies. Inevitably, then, its history is fodder for acrimonious disputes.

Read the whole thing. Everyone remembers and memorializes the horrors of the Holocaust, but the Soviets intentionally starved tens of millions to death during the thirties, and most people know little or nothing about this.
