Ok read last bit too, not much to add apart from his thoughts on whether Putin could press the red button:
He says no and gives 3 reasons -
1. There is no "red button", but a chain of command. It won't be just Putin blowing shit himself,
2. Few doubts about whether it properly functions (chain of command i think). My lack of russian forbids me translating this, but think he means there might be breaks in that chain, where somebody doesn't really know how and what to do exactly (not sure on this),
3. He doesn't believe that somebody, who is afraid to let his closest advisors and ministers, be it because of covid or assassination attempt, is going to off himself like that. If you're that scared to die, how are you going to kill yourself and everyone around you like that?
Thanks. I do wonder if, given abject failure of the invasion and attempts to seize Kyiv or other major targets, Putin tries to use tactical nukes and the military command staff refuses. Rather than the oligarchs rising up, I can only really see potential for the military chain of command or FSB to try to end the war and potentially depose Putin.
