Stalin was hard on Ukrainians. Trouble is there is a large population of Russians in Ukraine. In past Czechs were in similar situation at start of Hitlers power. They had significant Germanic population who were getting
short stroked. This gave Nazis excuse to “ liberate”. Similar politics were the cause of the troubles in Balkans , Bosnian war.
I doubt we do anything, Europe will do nothing with US “behind” them. If
Putin doesn’t pull genocide the west is going to act like it’s not happening.
After all every thing here is peachy, no reason to rock the boat.
