North Korea will use chemical weapons should they launch an attack on the south. They plan to blitz Seoul and then sue for peace once they have the city. Easy to do with the DMZ being so close. They have alot of old bitter men who want revenge...they havea peasant population that knows very little of the West. They all pretty much buy the program. Contrast this with Iran. They have a bigger, and better educated population that has numerous contacts with the West. They could be swayed. A moderate regime could take power and be delt with diplomatically. If North Korea falls u will have chaos. China will have a flood of refugees..no telling what affect that will have on pro democracy groups inside the PRC. The South will also havea flood but they are and have been prepared for that for some time...that should start us off. Good thread.
