According to Russian Media, major changes to the leadership of the Russian Ministry of Defense including changes to the current Defense Minister, Sergei Shoigu and Army Chief of General Staff, Valery Gerasimov have reportedly been agreed upon in order to stop the march of the Wagner PMC group towards the capital of Moscow; these negotiations have also reportedly included the assured “security of the Wagner Group.”
Here is my pet theory.
Originally, Prigozhin was driven to drastic measures due to his refusal of nationalization of Wagner. Now Lukasenka was asked by Putin to deliver a message to Prigozhin that he may allow Wagnerites to live under some kind of security arrangement.
All of this is driven by both Putin’s and Prigozhin’s desire to stay alive, with Lukasenka as a middleman.
