Some countries can be hellbent on self-destruction if they feel their "national pride" is being offended.

And European messaging is... strongly in favor of Ukraine but at reduced/no cost for Europe. So in practice European messaging is actually weak.

There are quite a few big European economies that would want to open up the Russian economy again. Conflicting interests are still fighting it out and we can't be sure which side will out. It could very well be that the winning political side in the West says a chopped up Ukraine is sufficient at the end of this war.

We'll see, it's super hard to predict.
