Or a more realistic description based on casualty figures is Putin's paranoia over Prigozhin's popularity has had let to Wagner basically destroying itself.
Not sure what the figures are now that fighting is more house to house but for most of this year, casualties were in the 7:1 range. Also worth noting is that while Wagner and the Russia conscripts wear themselves out, trained and well supplied Ukrainian forces are gathering in Chasiv Yar waiting for the mud to dry. As Ukraine is deploying Challenger II and Leopard II tanks, Russia is deploying T-55s.
