That's the thing, isn't it. What I want Europe to do is probably not the best thing. But, I do think that we are seeing another Czechoslovakia in 1938 (and obvious reference to the Prague Spring in 1968), and that no firm united response will be very bad. The problem is, Italy, Germany and Austria (no jokes please about the gang's being back together) are not going to do anything that will compromise themselves. Italy is almost totally reliant on Russian energy, Germany may have protested Schröderization (Gerhard Schroder, or Putin's best puppet), but they have Nord 1, so the halting of Nord 2 is not nearly such a big deal as they implied and let's not forget Deutsche Bank. We have a pretty strong historical grasp on what happens when you placate aggressive expansionists, they say "Thank you!" Then expand aggressively.
If I were in Estonia, or especially Lithuania because of Kalinigrad I would be very afraid. The Ukrainian writer Ivan Drach wrote that all their cultural efforts under the USSR were 'a rose under a bulldozer', and I think democracy in Ukraine is about to go the same way.
I genuinely need to do more research though, I hate not having a clear idea, especially as this is something I'm interested in.
