>On the other hand, a not-so-intelligent person that blindly followed protocol would have caused the downfall of the US and Soviet Union
I was reading on the Cuban missile crisis last night. There not one but several instances where the Americans said 'if x happens, we nuke the soviets', and then when x happened they didn't (for example, the downed U2 incident). The Soviets probably had just as many of those incidents. I think it really shows that deep down nobody was actually ready to go to war, so in all the chances they had to launch they chose instead not to.
