In regards to the urban vs suburban rural.  That would still fit the military map I believe.  It did remind me of this little discussion by Walter Russell Mead in a post about NY and disasters. After Sandy: Can New York Be Made Safe From The Sea? Should We Care? | Via Meadia The urban centers are a century behind the times.  Built as water ports and then expanded as spoke and hum rail centers.  Technology has made dispersion possible again.  But then, the Left is obsessed with killing the auto and recreating the urban center hub.  But with some odd pathology as they outlaw the icky manufacturing in those hubs.  As an irony, the efforts to save the legacy cities will likely accelerate their decline as taxes and recession push people to less costly places to live.

In the 18th century being close to ports and good rivers was crucial; in the 19th century the industrial revolution and the rise of the railroad created the hub and spokes model of city center and residential suburb that most of us instinctively think of today as the urban ideal. In the 20th century the rise of decentralized automobile based transit plus cheap electrical power promoted the rise of increasingly autonomous suburbs and cities like Los Angeles with relatively underdeveloped centers surrounded by massive sprawl.
