I learned something interesting in grad school. It is that the Nash Equilibrium for mutual assured destruction involves the occasional nuclear explosion simply because players must be credibly irrational for the threat of deterrence to be effective. I can't figure out if this is interesting or crazy. But the fact we're not all dead suggests to me that rationality is overrated in politics as in economics.
