I wouldn't make it about ethnicity. Making it about former Soviet republics and members of the Warsaw pact is the problem, from Russia's point of view. A problem that, in hindsight maybe, is so obvious and so guaranteed to come (Russia complained about NATOs eastern expansion for decades) that it seems surprising that NATO doesn't seem to have an answer. Hell, when Russia annexed the Krim and tried to annex parts of Georgia one would think NATO would have gotten a clear wake up call.
Germany makes deals with Russia to get their gas (NS1 and NS2) and only recently they declined NS2.
Basically we (EU) are giving Russia money to create army, instead of ditching their gas, oil etc. and buying one from Scandinavia and US (now when Russian gas prices are higher than the ones form the mentioned countries). And destroying NS1 and 2.
