What kind of problems is North Korea causing in the world today?

Trying to get Nuclear and spreading know-how to terrorist regims ---- North Korea is not the cause of the problem: The problem was caused, by those who opened up nuclar power, and dropped the ultimate Terror Weapon. They are the problem! Korea is but a tiny nation, standing up to have the same rights as all other nations. The initiators of atomic fusion, have completely failed to take responsibility for the error they have made, and delight in accusing others.
