Practical solution = give in to all of Russia’s demands.
You think they’d stop there?
The only way they'd be stopped is by ensuring that Ukraine and all border countries in Europe and potentially in Asia get strengthened past what Russia could even consider any more aggressions.
However that'd still leave Ukraine @#£%ed over royally. I suspect that for this to end, the Donbass region will be "independent" in name yet vassels of Russia and Crimea will become accepted as Russia proper. Russia will have to cough up a lot of cash for this and that would go to rebuilding Ukraine. It ain't fair, but what is?
Ukraine will require security commitments and I would guess at associate membership of NATO which in essence is NATO but can be sold back in Moscow.
Can't see any of this happening until Ukraine's backers can't see the returns on this. Russia will keep on for as long as it takes or until the defenestrations hit Putin and his cabal.
Longer run, I'm guessing that until Putin and his cronies exit the stage then we're not going to see any big rapprochement between Russia and the west. Hopefully when we get the next re-set with Russia, we'll not be money laundering and enabling criminal state behaviour like we have the last couple of decades- we need to become friends again but without promoting the dirty side of the current regime and bringing a more normalised Russia back into the fold.
Meanwhile, hundreds of kids are getting slaughtered daily for the ambitions of that ratbag Putin. It's a kin mess.
