Well with Bin Laden now dead I suppose the US needs another boogie man, despite what one may think of the government in North Korea it's leaders aren't stupid enough to declare war on the US.
Just an question on my part here because I honestly want to hear what people here think:
Why is it that the US/UN insists on sanctioning countries and then is always surprised when these countries dislike them for it? I think the US just likes to have an enemy to point to in their news rooms.
As for having nuclear weapons I only know of one government that used them in a war and it wasn't North Korea's.
