Wagner is not independent and self-sustaining, the way Putin has needed us to believe.
So we've got Pregozhin running around in Africa and Syria, et al, committing atrocities we'll find hard to believe could ever be carried out by honest-to-god humans. And those will be the atrocities that the investigators and their bosses will allow us to be aware of because some of them are bound to be so horrendous, nobody wants to know about them. Ever.
The point that needs to be hammered on is that this shit is not simply being done by rogue actors who are unaffiliated with Moscow.
Putin sponsors Wagner, Wagner is acting on behalf of Putin, Putin is largely responsible for Wagner's behavior. The Russian government is committing war crimes everywhere it goes.
Putin will not survive this war.
