I watched the beginning of Oprah the other day to see a small portion of Lisa Lings trip into NK, quite interesting, wish I had cable to watch the full program. She went with some eye surgeons and after fixing cataracts the people got up and thanked a picture of the first emperor of NK and the current crazy dude for healing them and never even acknowledged the doctors as having a hand in the healing. There are no advertisements except government propaganda banners and no tv, radio or news link to the outside world.
I bet only a handful of North Koreans know that either there was no nuke or it failed to work properly.

I'm betting it was TNT or other explosives, as a general nuclear explosion isn't that complicated with the right material.
