Yes, as a matter of fact I did know that Stalin was Georgian. So? He didn’t care about that. He wanted the Soviet Union to be easier to rule, and right or wrong he thought making it less ethnically diverse would help with that goal. He didn’t want the USSR to become more Russian out of some kind of ethnic superiority garbage like the funny mustache guy from around the same time. He wanted it to further cement his control. That was pretty much the primary motivation for everything he did. Motivation isn’t really the issue with that kind of thing though, is it?
