Your last paragraph lacks any merit as an argument. It's just a personal attack.
Why do you think he attacked Ukraine? For the now totally destroyed steelworks in Donbas? Or maybe the coalmines? Hitler had the same idea. Or simply to overrun Eastern Ukraine? To secure his route to illegally annexed Crimea? To show the world he has balls? To restore the Soviet sphere of influence? To reconnect with the lost soviet Eastern Europe? Remember? It was all stomped on by the Soviets. Maybe you and a million other idiots cheering him on are too young to remember the Iron Curtain. He never forgave whoever he blames for the collapse of the USSR and its colossal empire. But it did collapse, and now he's trying to rebuild it, at Ukraine's expense. Wanton destruction is all it amounts to. A million dead, and how many maimed and wounded, orphaned kids, childless parents, dreams shattered along with homes, factories, dams, power plants etc etc. He's solely to blame.
