Lolz do you really believe this?
Russia already lost this war in terms of what it set out to do
1. Prevent Ukraine joining NATO - not only has that spectacularly failed, but Finland joined NATO - doubling the length of the border
2. Make Ukraine a vassal state - that failed in March with the Russian loss at the battle of Hostomel and of Kyiv
Then the Muscowites had secondary plans:
2.1. Make Ukraine land-locked - that failed in June with the defeat at Mykolaiv
2.2. Take everything east of the Dnieper - that failed in September with the huge wins by Ukraine east of Kharkiv and was cemented with the Ukrainians liberating Kherson
Now Moscow is trying to grab parts of the 4 provinces - we still have to see how that plays out.
But Russia has lost, badly - the best it can hope for now is to keep Crimea and be a Chinese vassal
