Today, Jevgenij Prigosjin, the founder of the Wagner Group band of mercenaries, went all in with his confrontation of the Russian government. In a frenzied speech, he said that "those who are denying us ammunition are nothing but traitors, helping the enemy break Russia's back".
Considering that the one who made the decision to stop supplying the Wagner Group with ammunition is probably Putin himself, we should not be surprised if Prigosjin has a fatal accident in the near future. People who oppose Putin seem to run a high risk of falling out of a window or have a sudden heart attack, but with Prigosjin it's more likely that he will be the target of an attack from "one of his own", a government plant in his own ranks who simply shoots him.
Prigosjin was once a very close friend and confidant to Putin, but at this point there is no way back into his grace.
