It sounds a little defeated, but hasn't nuclear war been inevitable since the invention of the nuclear weapon? if no, why not? It's strange how distant the idea of nuclear war seems to my mind when I try to imagine the perspective of someone who lived through the Cold War. It's even more strange to imagine my own country as being a nuclear instigator. Metal Gear Solid is the closest I've come to nuclear doctrine, and in that game the US is there to stop a terrorist nuclear threat and protect deterrence, not keep the nuclear option on the table and potentially flush deterrence down the toilet. It causes some dissonance.
