This isn't a computer game where your objective is to clear the enemy from your territory and once you do it you win.
Do you think Putin will throw in the towel if he is pushed out of Crimea/Donbas etc? I don't see that happening.
Will someone throw him out a window? Maybe, but that is just more uncertainty.
Lol computer game.
Its to do with NATO and the EU for starters. Primarily NATO.
I have no idea what would cause Putin to throw in the towel. People can speculate, the only person who knows is Putin.
If Ukraine can push Russia out of their lands completely then its pretty obvious the military strength at that point demonstrates that at that point Russia cannot take Ukraine.
Ukraine have stated their aims, no one sensible has rejected them, some doubt they are achievable, thats different.
Ukraine have said they have no intention of going into Russia. And I suspect are told regularly to remember that to keep the support and arms flowing.
