In the command centers there are special clocks ready to tick off the minutes elapsed since `` E hour ''.
`` E '' stands for `` execution '' -- the moment a `` go order '' would unleash an American nuclear strike.
There is little time for the men in the command centers to reflect about the implications of these clocks.
They are preoccupied riding herd on control panels, switches, flashing colored lights on pale green or gray consoles that look like business machines.
They know little about their machinery beyond mechanical details.
Accidental war is so sensitive a subject that most of the people who could become directly involved in one are told just enough so they can perform their portions of incredibly complex tasks.
