I have to wonder why only a couple of people are worried about N. Korea's nuclear capability. Unless you have a plane ticket to somewhere veeeery far from here you should be worried. N. Korea is an impoverished nation and the idea that they would sell fissionable material and the technology to make a nuclear weapon to a group that would use it on us is not far off. Al Qaeda, for instance, has the money and the patience to construct a nuclear weapon. They need look no further than Iran for scientists capable of putting the whole thing together. Add to this the fact that Russia is missing about 100 of its "suitcase bombs" and hundreds of pounds of Strontium-90 and you see the potential for serious trouble.
