There's no great outcome for Ukraine vs Russia. No matter what, it will be a giant vs a midget with gifted brass knuckles and steel-toes.
The only ones who really benefit from Ukraine fighting the good fight are the military contractors and Europe at large. Russia has burned through every bit of political and economic capital they have on the global and European stage to conduct this war. If they had won in a few days as originally planned, Russia would be in a far stronger position. As is, I don't see a great outcome but Russia won't even think about being aggressive versus NATO nations for the foreseeable future. It's a win for us, but Ukraine is pretty much ed in 5-10 years, max, as far as I can see.
