My only concern is, why are so many in the West so keen on countries overthrowing their elected leadership? Granted most of the EU's concern is probably with natural gas, the US is probably hoping for some Putin embarrassment after the US's botched Syria approach
Consider the scary thing here:
To AGAIN start invading and taking pieces (Transnistria, Georgia, etc) of countries in Europe is not just small meaningless realpolitik, as you imply.
Especially since the motivation is "Protecting Germ... Russian speaking populations"... :-(
What will happen now is that the West will continue to say "Peace in our time" while starting to also rearm.
Are you seeing the obvious parallels here? You need to wait for Putin to get a moustache first? :-(
