Putin took the civilian route and “won elections” before the leapfrogging the presidency with Medevev and eventual solidification of his autocracy. He is a dictator in autocrats’ dress, faux elections and rivals aplenty, but not a general or warlord. Accordingly he insulates himself from meaningful challenge, which (like Xi and the CCP’s leadership) requires culling anyone competent immediately below you, or keeping them distracted with intra-competition for favor instead of seeking the top role.
A crumbling Muscovy regime, a fractured society with war fatigue, an arsenal of nuclear weapons that are scattered in Russia and in client states like Belarus, an ocean of conventional arms and equipment, Russia set up in a war economy, and then add a power vacuum are NOT positives for Ukraine, Europe, or the world.
During the fall of the Soviet Union, there were a lot of CIA agents and friends running around trying to secure and round up those nukes, lest they enter the black market or the local warlord/strongman decides “that’s OURS now” and another nuclear actor is on the chessboard.
Though the deconfliction hotlines are broken, non-proliferation treaties not renewed, and hypersonics changing the viability of ‘first-strike’ strategy, Russia still is a known actor. Someone like Prigozin is not, and that’s my point. Putin will play ‘the game’ of great power competition. A blowhard populist with an insecure power base and multiple rivals has a very different incentive structure, and may do the unthinkable if it means solidifying their hold on power.
