What is he even trying to do?
There's no chance of an actual coup without support from the people or the army, and he's hated by both. His usual dramatic requests for more money and equipment won't work if the first thing you do is denounce the War, and nobody with morality or a conscience would have become the head of a Russian paramilitary group.
I'm as confused as anyone reading this. Is all of this an extremely risky bet to get strategic control of the Russian army? In that case it seems to have failed spectacularly.
