Vova will have to purge whatever is left after this coup.
Doing so will make an already paper-tiger of an army/bureaucracy even worse off, as paranoia and shows of loyalty will be paramount, not effective fighting ability. Think North Korea, but even more so.
Whatever command structure of the army is left will have even worse of a time in Ukraine and, especially, in Crimea.
Vova is running out of cards to play, Wagner having now taken some double-digit percent of his remaining deck.
When Ukraine pushes into Crimea, the chances of nukes going off goes up a lot now.
