At what point, if ever, in Russian politics has self-canibalisation been a problem for them?

Putin has thrown down against Prigozhin, brought Alltwen arms of State to bare... and allowed him to walk away...?

If you think he's blundered I would caution about underestimating him, a brutal, ruthless bastard... for sure, but not a fool....

If he was a fool he wouldn't have got to the position he has at Wagner in the first place...!
