Old mate Prigo seems to be in a spot of bother....
Seems that he was actually hoping to catch Gerasimov and Shoigu in Rostov, but FSB got word of it and removed them. From there Prigo was cuffing it and bit off more than he could chew. He's now a completely spent force and is rethinking his possibly very short future.
I Think people might be overplaying the "Putin has been weakened" line, though. Many dictators (Mugabe, Maduro, Mao, etc.) have faced worse things than this and lived through it to continue their rule.
