In your post you wrote: > managed to coordinate their control except for North Korea. I'd like to suggest to you the following theory: North Korea is a buffer state. It exists by tacit agreement between china and america. Chinese launder bribes to american tech and weapons manufacturers by ordering NK to do missile launch. Ahead of this congressmen and manufacturers buy stock in these companies. NK launches missiles. Media runs fear-porn. The stocks of manufacturers go up. Congress approves more defense spending. Everyone involved makes money on their investments. Everyone gets paid. The people given the tips ahead of time do whatever job they were bribed to do. NK exists mostly as a chinese experiments lab, bribe launderer, and as a pylon of u.s. defense manufacturer's justifications for funding and existing. Contrary to all intelligence chatter, u.s. officials spreading rumors, and news talk, on this basis we can say NK and south korea will probably never unify, at least not in the short or medium term (next ten years). There are some indicators to the contrary, which would tell us all sorts of useful things about u.s. relations to china and who truly own who, but until they come to pass, I'm not counting on it.
