The North Koreans want us to believe that they are ultra-desperate, crazy, and about to explode; under the belief that we will grant them concessions rather than go to war against people so insane (especially as we get closer to going to war against Iraq).
This document would seem to fit in well with their aim, whether it is true/real or merely a "plant".
The societal situation alluded to in this internal report is confirmed by eyewitnesses who have defected, and Japanese journalists who visited DPRK, and others which report things are really at a strain and the govt. is getting restless.
Recent official DPRK documents published as public notices in open forum in North Korea, also tend to show their concern, what with the nature of their dictates. As a result, I respectfully dismiss this as 'disinformation', as you may have suggested.
