What I'm not seeing mentioned anywhere yet is money, and the role it played and is playing in the relationship between Prigozhin and Putin.
Putin bankrolled Wagner initially. Is he still paying for it? To what extent have Prigozhin's 'investments' in Africa and Syria been able to give him an income?
Armies are expensive to maintain in peacetime. Being in an active war is a huge cost multiplier.
Another thing to consider is where does Wagner get its supplies from? I'm talking about bullets, shells, tickets etc. From what I've read it comes from Russian authorities (of whatever form). Fuel, food etc he can just buy anywhere, but the military stuff has to come mainly from the Russian armed forces.
I suppose what I'm wondering is how 'independent' Wagner is, and maybe there's a mismatch between reality and Prigozhin's perception.
