Mad is the argument against nuclear war when the actors are somewhat reasonable. What happens if you get unreasonable actors that don't really care who dies, their countrymen and themselves included. At that point, we are totally screwed. I would be surprised if these type of people don't exist. Lets hope they never get near a nuclear weapon.
Somehow Kruschev, Stalin, and friends were not crazy enough. It's easy to call someone a nutjob. It's hard to know what it's like to face the sober realization that you could, if you wanted, end human life on earth.
