I love the North Koreans, they are so fucking funny.
The excuse for their need of nuclear power is so they can light their cities, and provide warmth for their citizens...
Ever see a satellite image of North Korea?

North Korea has no bargining chips except nuclear weapons, we are all getting blackmailed by them to feed their people since nearly 80% of their money goes to the military.
Take away their nuclear weapons, and they are no longer the big swinging dicks in that part of the world.
