Russia's defeat will be announced by CNN. Russia can't win because it doesn't own MSM.
It is a completely different question what and who will benefit from the outcome of this conflict. The U.S. has profited well on military contracts, weakening of European partners, corruption in Ukraine itself, which has now completely lost its independence. Russia has gained new territories, managed to get rid of European dependence and, as a result, is eliminating the military conflict at its borders. China has shown that the old world order has lost its power, that the West has lost the ability to resolve issues.
In the end, the fact that Russia lost does not matter, because it was not a game. It was just a military operation with goals too ambitious to achieve in three days. 15 years is more likely.
