Game of chicken being played out by kremlin and prigozin I suspect.... Possibility putin is using stalin's model towards the end of WW2 where he held back and let the nazis and Poles fight it out to weaken both his enemies.
This is being played out just for the domestic political audience as they are have both secured pariah status with the majority of the international community. If the implosion does happen in russia, I suspect we will have a variety of actors vying for the top job, some backed by the West and other more moderate Eastward looking candidates backed by China and then some that are aligned to the FSB/kremlin inner circle who will want to play the continuity card.
It's Shoigu,he is arming his own PMC and trying to make them look like hero's,whilst making Wagner look cunts.....they are all cunts by the way.
I'm dubious also but let's wait to see if they provide any evidence - must be a wet dream for all those arms manufacturers out their getting this real live data and technical analysis
They can go to Mach 10/12, hypersonic is over 5.
