When North Korea Falls - Robert D. Kaplan

Yes it's long. But, when you have read it you will know more about NK than the upper 3 levels of this (mis)Administration.
(Unless of course you have the I.Q. of a pretzel. But, then you still would be able to out wit Dubya.)

Kim Jong Il’s compulsion to demonstrate his missile prowess is a sign of his weakness. Contrary to popular perception in the United States, Kim doesn’t stay up at night worrying about what the Americans might do to him; it’s not North Korea’s weakness relative to the United States that preoccupies him. Rather, if he does stay up late worrying, it’s about China. He knows the Chinese have always had a greater interest in North Korea’s geography—with its additional outlets to the sea close to Russia—than they have in the long-term survival of his regime. (Like us, even as they want the regime to survive, the Chinese have plans for the northern half of the Korean peninsula that do not include the “Dear Leader.”) One of Kim’s main goals in so aggressively displaying North Korea’s missile capacity is to compel the United States to deal directly with him, thereby making his otherwise weakening state seem stronger. And the stronger Pyongyang appears to be, the better off it is in its crucial dealings with Beijing, which are what really matter to Kim.

To Kim’s sure dismay, the American response to his recent missile tests was a shrug.
