Forgive me but NK actions are an attempt to get further concessions from the international community (remember what they got for signing the nuke pact and installing monitors last time?).
This time they'll bend over again for just some more food and a few billion dollars in aid.
The difference is that this time GWB rather than BClinton may not give it to them in which case the only chance of war is the bad guys rollling south to divert eh population from starvation. But very very unlikely. GWB has no requirement to roll north.
If NK did roll south it would serve the SK's right for treating the yanks like sh*t recently though! :-X
Motives aside. North Koreas actions of removing IAEA (International Atomic Energy Agency) seals from their nuclear facilities, means that fissile material (Plutonium and Uranium) cannot be tracked. The only reason not to have seals in place is if theyre doing something they shouldnt. Even if they do replace seals and allow IAEA inspectors back in, they will have time to have moved fissile material about and have started their reactor producing low irradiated fuel which could easily be reprocessed in order to get high fissile Pu .. and what does it matter if whats there when the inspector return doesnt quite add up to what was there when they left?
War or not, nuclear proliferation wont help anyone.
