I added this to another thread but no one picked up on it. I basically comes down to bringing information to the N. Korean people about the rest of the world in a non threatening way. It can't be just straight western propaganda, but entertainment stories with a background that is normal life in most democracies. I don't know why we can't flood the country with flash drives, Micro SD cards by the billions. Getting more computers in would be more difficult, but the $5 Raspberry pi could be configured to play videos, or present loads of text.
Here's an interesting article on how to handle North Korea.
Something is deeply wrong when the world allows a dictator to starve millions and still retain power. I would use the same logic of world war II, we killed a couple hundred thousand civilians to save many more lives. We can try to preserve as many people as possible but getting rid of the little dictator will save more lives over the long term.
