Sounds like Plan B was a bust. Russia's army has been unable to sweep aside the Ukrainian army in Donbas and Lukhansk.
So will Putin mobilise the entire population of Russia in the attempt to save his own skin. Because that's what this is about now. It's no longer about Ukraine. These people will be useless in that war. They will die in huge numbers. He has a different goal. Plan C. He's preventing young Russians from organising themselves against him.
Putin is every bit as terrible as Hitler, except for one thing. Hitler's Germany was competent.
