Allow me to hate the (heh!) mainstream media just a little, then I'll return to regularly scheduled programs.
It appears that the media is tired of the narrative of Russian failure, more than Russia is tired of failing. The story needs a new twist. So Russia captured a couple of cities and have momentum.
Serious analysts look at the situation and estimate that Russia is running out of everything and has about a couple of months of ammo left. Remember, the Russian tank factory is closed for lack of parts. Russia is running on old stock, and I'm certain that's why Russian missiles are unreliable. There's not much new stuff left. Russian generals have to think about the consequences of having no modern weapons in the arsenal. Everyone will know! Everyone will see the Big Board!
Russia will use T-62 tanks. Russia won't use SU-57 stealth fighters. If you can't use your best plane because you're afraid it would be shot down, but you can use obsolete museum piece tanks because you're running out of better slightly obsolete tanks, what's the war winning move?
