As a European, I feel that we are too disconnected from this affair. Just as with the Ukrainian civil war and Crimean annexation, a big part of this conflict is a conservative, repressive, Russia/Putin sponsored regime at odds with a population that identifies more with European/EU values... especially younger people.
Russia see the dignity, prosperity and freedom of several nations as trivial relative to their "vital concern" of having a buffer between them and "The West."
I'm not saying that we can or should escalate recklessly vis-a-vis Russia. I am saying that they are our neighbors too, not just Russia's. We have our interests too, and more importantly our solidarity. The Lukashenko regime is anachronistic, brutal and failed.
This is not a foreign affair.
I understand and even sympathize with Putin's concerns on encroachment. He lays them out clearly enough. I will also admit that mistakes have been made, and the the US played its hand too aggressively in the 1990s. I also think that the EU (and NATO, if the US is willing) should negotiate a peace treaty that addresses these. I also genuinely believe this is possible.
For that to happen though, we need to take a much firmer stance. We need to be as interested in our neighbors as Russia is. The whole premise of the EU is peace and sovereignty. Those values need to be represented here.
Ukraine was abused because of their desire to join the EU, and we treated it as above our paygrade. Now, Russia is openly propping up Lukashenko. Next year it will be Lithuania, Estonia. Putin might decide to intervene on behalf of Victor Orban. We're in this one way or another.
