It could end up as a pyrrhic victory for Ukraine. As this article points out Ukraine has still lost significant territory on the South and East. Does Ukraine have the combat power to retake it? I'm not an expert but it would be extremely costly for the Ukrainians as offensive operations cost much more in terms of supply and casualties then defense. I think that as some point Russia will "claim" victory and set up puppet states. Ukraine likely won't have the combat power to oppose it.

Yeah, that’s not a very good article. I know it’s from Time magazine or whatever, but it reads like it was written by a very young person.
