Who could possibly be the loser in this situation? Is it:
Ukraine, All of Europe, the USA, and the rest of NATO?
or
Russia
hmmmmmmm
Such a tossup /sarcasm
It’s Russia. Russia is losing. They’ve got enemies within and all around, the world is closing off trade with them and they don’t have half the local resources that the failed Soviet Union once had. Once this is over, then there is a non-zero chance they spend the next half a century competing with the east as Cheap Labor for China and the USA.
