What Government would take over NK that doesn't already have nuclear capabilities? Pakistan is a different beast. I'm not an expert on the middle east by any means, but it seems to me a lot of nations around it could theoretically start the fight. I believe that would cause a US/Indian/China intervention, if not on behalf of Pakistan (in the case of Chinese and Indian territorial disputes), then in defense of their own interests in the region (the territory).
