> What Russia is trying to do is ensure it has a strategic buffer zone between it and the West and friendly rulers and states on its borders, much like any state with Russia's military history would be interested in doing. Combined Russian/Soviet casualties in WW1 and WW2 were on the order of ~60mm people out ~160mm total.
Actually, Soviet Union started WW2 together with Nazi Germany by signing Molotov–Ribbentrop pact [1] and annexing Estonia [2], Finland [3], Latvia [2], Lithuania [2], Poland [4] and Romania [5]. Quite a nice buffer zone there.
So now Russia (legal successor to the USSR) is considered a victim of WW2 and is afraid of invasion from the very same countries it has annexed by force before?
