I honestly don't know that much about NK. Watching CLOY reminded me of growing up during the Cold War, the USSR & satellite states but most of all, East and West Germany. I knew a couple of people who escaped from E.G. I imagine it is similar to NK & SK. I remember when Reagan made his speech, in 1987, challenging Gorbachev to "tear down this wall". A year and a half later, that wall did come down and there was much rejoicing & celebration. I hope the Koreans can find a way to unite. . . . As for NK, all I have is that satellite pictures taken at night show a very dark & unlit NK while SK is very bright.
