because it was clearly evident that the KEDO was not going to live up to it's obligations under the agreed framework deal made in 1994 (which only came about because then South Korean president Kim Young Sam said that if the US attacked North Korea, South Korean troops would not budge an inch in support). Now I don't know if you're familiar with this little tidbit of information, but the North is highly dependant on outside energy supplies, so they were trying to build their own (ie nuclear power).
However, North Korea knows that they need nuclear weapons now more than ever because they've seen what Bush will do to countries that have no means to defend themselves (besides killing thousands of South Korean and Japanese) against America. Think about it for a second. If North Korea wanted to attack, do you think they would do it now, when the country is still chronically mal-nourished, or back in the late 70's early 80's when they had the support of the USSR and China, an dthe country was still in relatively good shape?
This whole uranium enrichment program is still very much undecided, they still don't know if the uranium that was reportedly sold to Libya (I just find that too convenient, Libya re-joins the "free" world, then bam...up turns the North Korean uranium) is yellow cake or refined uranium.
Article from today's Korea heraldI'l also argue with the author of the article I linked to: he says that "There is no innocent explanation for Pyongyang's enrichment program and hardware acquisition around the world and therefore, for related fuel developments at the front or "uranium" end, it states.
"There is no economic rationale for an independent enrichment program in a small country like North Korea, with plans for only one or two light water reactors before KEDO postponed the project." "
However, there of course is the small matter of fact that North Korea relies on coal and hydroelectricity for power, and both of those are somewhat unstable in North Korea. Now why wouldn't they want to develop another means of generating electricity...
Let's hope that the two Koreas can come to an agreement on their own, without US intervention (the CVID demand is ridiculous). The more South Korea invests in North Korea, and the more meetings they have, the closer they can move toward peaceful reunification.
