The near-collapse of the Russian army near Kharkiv begs the question: What can the Russians do, now?
The Russians seem to be running out of available soldiers. Other places where the Russians are involved
are taking note. Putin has been trying to keep to his bargain with the Russian people: He gets to run political, military and foreign affairs as he sees fit and the people are left alone to live their lives. But there is
pressure to stop with the "special military operation" bullshit and declare it to be a war.
But then what? Even if Putin orders mobilization and a massive traft, those draftees need to be trained, which will take months and lots of trainers. Unless, of course, Putin would send them into combat barely trained, which would make them more cannon-fodder than soldiers.
Another problem that Russia has is that they find themselves in the same position as Nazi Germany: They only have the resources that they can command. The North Koreans will sell them old equipment, the Iranians will sell them drones, but that's about it. Nobody else will, at least, not openly, for fear of incurring sanctions from the western nations.
As the Ukrainians make gains on the battlefield, more and more
tales of Russian brutality have come to light. All give the lie to the Russian claim that there is no difference between Russians and Ukrainians. The Russians claim that they are trying to "de-Nazify" Ukraine, but the truth of the matter is that if there are Nazis in this war, they are Russians.
Putin well knows that his own survival depends on the aura of competence and power that he has in Russia. Fallibility is often fatal in Russia. There is no incentive for him to stop the war on anything less than terms favorable to Russia, which apparently is not going to happen in the near future. Besides that, if he loses power, he loses his hold over the oligarchs and possibly most of the money he's grifted. They'll claw a lot of it back from the various shell companies that they are holding for Putin.
This is a stink that will stay with the Russians for a very long time, even if
some filthy companies continue to do business with these 21st Century mass-murderers.
So, how does this end? I have no idea.
