Nothing to do with getting Ukraine into NATO. The fact is that no European country, especially those that used to be part of Russia wants anything to do Russia, especially this version of Russia.
Europe has been postponing the inevitable. This Russia has been blackmailing them for a long time, it was long overdue that they cut their losses and move along.
They called Putler's bluff this time after being hesitant with Crimea, and Russia is the one that's going to suffer the consequences in the long term, because their economy is simply not that big, and without selling energy and burning money on the war it's only a matter of time until they fold.
