We in the West were almost treating Prigozhin like a anti-Putin freedom fighter, ready to protest Putin's ill-advised Ukrainian war, yet:

I suppose we need to remember that Prigozhin and others are to the political right of Putin, and wanting to take Russian hegemony further. He seemed the Col Kurtz character in "Apocalypse Now", a good attack dog that started disobeying his master.

In any case, this has to remind any Russian that Putin will always throw you under the bus, which (like Trump) will eventually to a coordinated pushback.
