Unfortunately for your position, the Ukrainians had no option at all, and your suggestion that they could have joined a kolkhoz is just ridiculous. The Russians impounded all grain and other harvest and prevented the Ukrainians from leaving if they tried to leave. The Ukrainians had no more chance of escaping than the Jews. Is it that hard to admit that killing gentiles is not a serious issue to you, only Jews?
