what does "The arcane mysteries of command decisions"mean?
The General's fears appear to have been justified. Had Russia attacked across the DEW line on the afternoon of November 22, 1963, the greatest military establishment in the history of the world might easily have been musclebound during the fifteen fateful minutes of warning time and perhaps even afterward, when second-strike capacity became a factor. This, of course, is conjecture. The arcane mysteries of command decisions are the private property of the executive mansion's West Wing and the Pentagon's E Ring, and doubtless they have changed many times since then. But Johnson's ignorance of Ira Gearhart's football was real enough, and so were Gearhart's difficulties with the agents of the Vice Presidential detail at Parkland.
