Imagine Russia not having it's shit together enough to put down a mutiny from a mercenary group.

We know Russia's military is a disorganized mess. Even a well-organized military can struggle with getting up to date information from the front lines. A military in an authoritarian country where people are afraid of giving their leader bad news?

Yeah, Putin doesn't know what's going on in Ukraine. Best to keep him thinking that The glorious Russian Army has destroyed 4000 Leopard 2 tanks today and the Ukrainian counter offensive has been a complete failure, just as his staff is telling him.
