By the same token, not all of these regions were uniformly hit. This includes Ukraine -- for example, the area where my family comes from did not see any kind of mass starvation (just hard times like elsewhere in the USSR). And this is why my Ukrainian great grandmother adored Stalin, while her Caucasian son-in-law despised him for his deportation of Muslim north Caucasians (Stalin's real act of completely intentional ethnic cleansing).
And this is unsurprising because the starvation was a failure of local authorities as much as it was of central authorities.
It is simply something that Ukrainian nationalists today ascribe to some Russian conspiracy to wipe out the poor, oppressed, anti-communist Ukrainian nation -- while in reality Ukrainians were as much behind it as anyone else, whether Russian, Georgian, Jewish, or anyone else.
