My hope is that Russia barely manages to defeat the Wagner group, then is left so weakened that their corrupt government completely collapses and real change can start
Yeah, but he's against the war in Ukraine. If anything he would probably consolidate power for the next 10 years and leave the rest of the world alone.
Lol, because that's how Russian warlords operate. "No, it's cool, I'll just chill here and not invade anybody".
Prigozhin is as bad (if not worse) than Putin. The rest of the world would be no safer with him running Russia. Best-case scenario is that this bullshit destabilizes the country to the point that Putin is deposed, somebody rational takes the lead, and they agree to cease all operations in Ukraine in exchange for western assistance putting down the Wagner rebellion. It'll take all of a week to stomp out Wagner, if Russia allows the rest of the world to do it.
