Most of what you say is true because the North Koreans have devoted all of their resources to their military, completely ignoring everything else.<quoted text>It was an astronaut that said passing over N Korea in darkness is eerie as the is not a light to be seen anywhere between S Korea and the China mainland.
North Korea has very limited electrical power.
If one googles North Korea and expands the little map that appears in the upper right of the page the first thing one would notice is that N Korea has very few roads. Looks like the fifth largest military in the world walks everywhere and those missiles are basically confined to the Pyongyang parade route.
It's my guess that one or two well placed US or S Korean missiles ends any conflict within hours sending the N Korean population into panic and chaos.
Meanwhile, N Korea has "never" tested the Musudan missile.
But you're wrong because a humanitarian leader like Obama would never target the North Korean civilian population and, in any event, the North Korean population is under complete government control.
Consider also the possibility of a massive land invasion across the border, something that neither South Korea or the US has the ability to resist.
