What is your solution? I guess if UKR gave up the Donbas, and Russia moved out, thats probably acceptable. Until the next move. If UKR hurriedly joined NATO, or got some level of interim membership that meant the NATO partners would step in, thats possibly a sound situation?
Solution? Why do WE have to militarily solve this struggle for freedom that we didn't start? Bringing Ukraine into NATO would be a presale ticket for a proper war, since the alliance would certainly occur and nobody is really enthusiastic about that - hence "only" the economic sanctions of the EU (yes, I‘m quite sure China will compensate that), aid deliveries and refugee admissions (Germany now has pretty much all nationalities worldwide conflicts and expulsions included, that cannot continue indefinitely).
Since the USA is also involved in a NATO alliance case, China would also be involved and we would have a proper, unpredictable conflict, if not WW III. And what is all this for? Even if Putin were to withdraw after a ceasefire agreement with the UKR because he probably doesn't have the right equipment in his box at the moment - he'll get it somewhere else and come back later. He will never accept knowing former USSR claim areas under the influence of a western alliance. He will argue that NATO is circling around as an aggressor on ("his" former) territory of the USSR and then uses this as a pretext for a "defensive strike", especially since he already has to swallow a NATO expansion/shift of interests with Finland and Sweden. But they both have been EU members since 1995 and are not at war with Russia - he cannot provoke much with that alone. Finland has already trained 280,000 active soldiers and a further 870,000 reservists who can be activated in its national defense program based on the experience it has gained.
