In about three weeks I will be in the JSA area at Panmunjom. I also believe there may be an opportunity to meet interesting people in Tokyo and if anything newsworthy comes of it, I'll post a FReeport and 'ping' you and others.
Kim Jong-Il's paranoia will work against him. It will further weaken the effetive functioning of his regime, just as in the case of Saddam Hussein. Many elites will really lose hope, and live in abject fear. And still it won't be completely safe for Kim Jong-Il and his loyalists.
