I don’t see how anyone conceivably can compare getting nearly 8 billion individuals to follow COVID orders where failure only requires 1 individual leaking the virus compared to a select few people who can launch nukes who all have to agree to go ahead with it and use that comparison to try to make a point.
Actually that is an amazingly good proxy for how effective MAD would be. Look at each world leader. Did they follow overwhelming scientific advice (backed up by peer pressure from all other world leaders) and publically promote lockdown, or did they publicwlly disown the science, announce their own solutions / policies etc.
Those that made official advice to "use aromatherapy" or something are people not likely to follow Game Theory.
