I don’t think either side will be able to decisively beat the other, but that’s not how these things usually end anyway.
Actually, I think it’s pretty funny in a sad sort of way that Americans don’t get how this is going to go. It’s really obvious that Ukraine doesn’t need to win, they just need to keep fighting until Russia goes home. Western aid isn’t even really making much of a difference in the eventual outcome of the war, it’s just reducing the damage that Russia is doing to Ukraine and bring that inevitable end closer faster. We’ve seen over, and over, and over again that once a group of people actually make up their minds to resist, there is nothing that can stop them. Even if the aggressor can bring overwhelming military superiority they will eventually give up and go home, and Russia can’t even do that.
The question isn’t who will win. The question is how many war crimes will Putin commit before admitting he lost this war in the second week.
