Kim seems to want more access to money, food and technology--if he can get it without loosening his grip on power. There may be other motives. China has been pressuring Kim to open up--mostly out of fear that North Korean intransigence could lead to a bigger U.S. presence in Asia. In Washington, U.S. officials say the root of Kim's shift may be that the Dear Leader has realized there's no future in being a rogue. It's a message Kim seems to have absorbed. The smiling fellow who waved his South Korean partner goodbye at week's end was already looking less like a wacko in search of a weapon of mass destruction and more like a grandfather in search of a hug.
