After years of debating and negotiations, North Korea has decided that they are going to do what they feel is best for their country and maintain an operable nuclear plant. It seems that North Korea simply wants to develop their nuclear program, while the U.N. wants them to cease and desist in forming their nuclear capabilities. 
If they have the capability and knowledge, then North Korea can do whatever they want within their borders, as it is their sovereign right to do so. And the U.N. has every right to protest the decision in Pyongyang to pursue nuclear energy. However, if North Korea feels threatened by other nations in this world, then can anyone blame them for wanting to be just a little prepared for the days ahead?
But what I find difficult to understand is why it is suggested that there will be dangerous “days ahead” if North Korea has nuclear power. Nuclear power is an efficient way to supply energy, in much more viable ways than mineral fossils ever will be. In spite of this, there’s also the havoc that can be wrought as a result of using nuclear weapons in war. Visit the ruins of Nagasaki and Hiroshima; it’s quite a harrowing experience, so I’ve been told. Is it impossible for people to use nuclear energy for strictly good reasons?
