Currently, liberating ever last inch of Ukraine in 1991 borders, end of Putin, war criminal trials (ICC), and the reparations from Russia. The possible implosion of Russia may just come along (and in which case Ukraine will likely want to take some too).

It's not "West's objective", it's their objective.

I see you people don't understand this, and I'm going to explain this to you as to hopefully comprehend.

You probably won't be able to find any nation more nationalistic than the Ukrainians, not in Europe at least. Ukrainian nationalism (often called "ultranationalism" and correctly so) is just incredibly hardcore and total, it's their actual religion besides their other religions (and they're extremely religious). The red and blue colors you may often see mean literally "Blood & Soil" (Ukraine's black earth).

Russians know who they fight, this is why they say "ukrainskiye natsionalisty" (and variants, many pejorative or sensationalist, as with the popular "Ukronatzisty" - the word "Nazism" itself is a neologism in Russia that was imported from the West only starting in the 1990s).

Croatian nationalism is kinda similar even if not that extreme, and they did take all of Croatia. And then they went down to Bosnia to quickly smash the Serbs also there, because of the Bosnian Croats living in Herzegovina.
