As a general rule, coups either coopt major parts of state force to either join in or sit out the conflict in the first few hours or fail quickly, as everyone defaults back to the mean of the status quo ante of state retaining control.

Prigozhin's coup attempt so far has failed to get any declared or ambiguous support, and MOD, FSB, GRU, Rosgvardia, and State media sided with Putin

So for folks thinking this coup will be successful, the chances are very, very strongly against that from here

Substantially weakens Putin's control either way; but this does not have any of the hallmarks that would make it a closer call.
@Pwnallthethings maybe a coup isnt the goal. maybe inspiring an assassination is easier?
@Pwnallthethings And hopefully breaks a few teacups.
@Pwnallthethings if he’s blaming Shoigu and the oligarchs for the war, but not Putin, maybe he’s giving old poots a way out of the war. Is he blaming Putin though, I’m seeing different opinions.
