Prigo doesn’t hate Putin, he hates the Ministry of Defense. He blames the Ministry for the failures of the war, and Putin has allowed Prigo to speak out against the Minitry because that takes blame away from Putin. Prigo probably wants to take over the Ministry and therefore control how the war is fought.
“he hates the Ministry of Defense. He blames the Ministry for the failures of the war,”
He hates that Putin gave MOD control of Wagner and has been resisting that take over. His objection to the conduct of the war is that all out war was not declared with far expanded goals. He wanted strategic control and direct command of Wagner... not just to be the owner.
This is his zenith. He won’t leave Rostov except under arrest.
