Moreover, there is a bigger danger. How can we risk placing the fate of humanity in the hands of ONE possible crazy man? Sure you can’t leave our nuclear response in the hands of a large committee, but, say, three men, the president, the head of the joint chiefs of staff and the speaker of the house might suffice as a decision making body.
After all, say that the Russians do launch a surprise nuclear attack on America. That attack alone might be enough to destroy themselves along with the rest of the world, even without a rapid retaliatory response from us.
In other words whatever the speed requirement is for a response to a nuclear attack on us is far less critical that allowing a single America of questionable stability to be given free rein to end the world.
