At this point, it’s pretty clear that the Russians have only the nuclear card left to play.
They’ve proven historically incompetent at training, equipping and employing soldiers in a conventional manner, no matter how many they have at their disposal.
So far, they’ve been good only at killing their own criminals — and then only to the extent that their public tolerates. Which is a lot.
The next few months will be highly interesting. Will the Russkies play the nuclear card? If they do, what will NATO’s response be? IOW, will it help them (the Russians)?
If the Russians don’t play the nuclear card,, can they survive? Depends on whether they bleed materially fewer 18-35 year olds than the Ukrainians.
My personal opinion is that helping the Ukrainians now is far, far less expensive — in terms of money, blood and hard military assets — than not helping them, and dealing with the Russians later.
