here's an interesting report on north korea:
http://www.globalsecurity.org/military/world/dprk/
lots of good info, but i found this article on a possible strategy interesting:
http://www.globalsecurity.org/milita...k/doctrine.htm
regarding the original article, i don't think the world will allow another "pre-emptive" strike on another country, although i do believe north korea is a danger. i also don't think china would stand for a "bomb korea until everything is flattened" strategy. The fact is that we can't do anything in north korea without china's approval.
