Russia might be so messed up that leading it is not desirable and attainable for anyone except quite crazy persons that are at the same time smart + competent enough.
Our current world order seems to have created a "power niche" in Russia that can only be filled by persons at the same time smart, crazy and competent enough! ...and we should also be wary of what kind of personal qualities we select for in people in eg. NATO or Chinese leadership, one could imagine embarking on crazier-than-thou leadership race.
This is scary as f! The rarity of the smart+crazy+competent combo is why we didn't off ourselves so far with nukes or by hacking into being stuff like, dunno, "covid ultra pro+ with prionic-inserts" or other horrible world-ending tech that is getting cheaper and cheaper...
