It’s a pretty good opportunity for peace, actually.
Lishenko is a pig and his troops were to blame for much of the war crimes Russian regular troops are blamed.
He’s also a survivor and an able tactician.
He (and everyone not either a Mis Lindsey Graham Warhawk or Putin fan boy) can see Russian troops inside Crimea are now cut off from supply. There are no reserves of value. The end is not near for Russia’s invasion, but it’s now inevitable.
He did this to save his own worthless rear end.
Russia now admits it is in a bad place.
This joker almost pulled off a Julius Caesar and marched on his own capital.
This gives Putin room to blame him as a betrayer and leave with some kind of honor, claiming he was betrayed (and avoid going the full Mussolini and swinging from a lamppost).
Progozhin is going to get Trotsky-ized, whatever happens to Putin in the end.
