I don't remember if anyone's posted this site up or anything like it before, but there you go. The site offers an inside look at North Korea as experienced by a North Korean defector. I don't know how accurate it is, though. Still, it is very interesting and touches on many areas. The following is an excerpt from the site.
"North Korea sees political chaos in South Korea as the best window of opportunity, though US and Chinese reactions to the attack remain important variables. The North will attempt to instigate turmoil in the south through its underground espionage network, and strike when turmoil combines with an international incident that necessitates large-scale dispatch of US troops elsewhere. "
Again, I'm not entirely sure if all he says could possibly be true or not, but it's interesting to read anyway.
