I just don't see that. If they're so strong why are they using weapons from Iran and North Korea? Why are their storage facilities shrinking, which Covert Cabal has been tracking from the beginning? They are making progress, yes, but it's marginal.
Russia is mostly a dirt-poor nation. Always has been. It can pay a lot of men to go fight on the front. The West has never wanted a fair government in Russia. So many of your views of Russia are counter to your views of a selfish, greedy and arrogant West.
As for the mood in Russia, I watch 1420 to gauge the sentiment on the ground. Old Russians may have some spirit, but I've not seen it in the young, even those who are for the war.
I believe you let your disgust of the West (understandable) cloud your judgement here. But we shall see. One of us will be buying the other one a drink ;)
