Its not a matter of having smart people.  Distance offers protection
against many risks.  The closer you put two critical systems to each
other (e.g. in the same building) the higher the risk a single
catastrophe (or system engineer) will impact both of them.  Of course
there are limits to diversity, earth is a single point of failure for
the foreseeable future.

I have no idea how many or where the cable entrance facilities are
located or how major cables are routed through the Pentagon.  Demarcs are
sometimes located in the darndest places a long way away from where you
might do your work.  It might even make sense to put an alternate
building entrance facility not on the side where the majority of the
networking was done.

In any case, classification level is orthogonal to quality.
