Sometimes the threat of war and invasion cuts through a bunch of cruft and corruption. This is another miscalculation on Putin's side. Ukraine was the comfort blanket for Europe keeping them complacent.
This crossed an emotional line with the entirety of Europe. Heck, I feel it in the United States. Russia/Putin are nuts and not entirely rational. They are actual palpable evil: a direct threat to your survival and prosperity.
Remember the dogs thing with Merkel and Putin? I'm sure the "elites" of the EU have wanted to get more coordinated against Russia, but the populace was a bit ... soft.
Putin may have motivated far more people than just the populace of the Ukraine.
Looking at the map and the conduct of the war so far, this is a massive geopolitical opportunity for the West. Set fleets of drones into Ukraine and repulse the forces. Actually, I would sucker Belarus into invasion (they've already announced it, have they actually done it).
That would provide a casus belli for Ukraine (ahem NATO) forces to then invade Belarus, the other major buffer state between the NATO and Russia. Topple their autocrat.
Then put Belarus and Ukraine into NATO. Then there is a wall of NATO states at the doorstep of Russia.
