It makes sense. He is the “manager” of Russian operations in Africa, whether those are mining or military oriented. Prigozhin has established a lot of connections there, ranging from warlords to politicians, and plenty of leaders are quite pleased with Russia. The Wagner group function as bodyguards for aforementioned leaders and help with “peacekeeping” creating a dependency that can be exploited in exchange for natural resources and political influence. His defenestration would do little to mitigate the Kremlin’s perceived vulnerability after the coup attempt, while being an enormous setback to their recent expansion.
