I know that very well. Hopefully the Western leaders will too. But they should have learned that lesson with Crimea.

It must frustrate them to no end when neither of these cards they used to successfully play work, and they check their playbook only to find that they have nothing else to play.

Yeah and it's not like this invasion came out of nowhere. Hello, Russia has been trying to reclaim former territories of the USSR piece by piece since its collapse. Chechnya, Georgia, Crimea. All these russian invasions the world looked past. The Ukrainian invasion may have been bigger, but if the Ukrainians hadn't shown the incredible backbone and competence at repelling the invasion and actually got large parts of their country occupied with no chance of taking it back, I guarantee that five to ten years later the world would have looked upon this situation with the same apathy they ascribe to those previous invasions. There is, infuriatingly, STILL opinions present that Ukraine should allow Russia to keep parts of its territory in exchange for peace. Some people never change.
