I think that pretty much is what im thinking too pete. Fair enough, north korea probably wont send one this way, but as you said, its much more effective, "worthwhile" and generally easier to just bomb south korea. But that still effects us because Im sure I saw a panorama episode where they said another large nuke could turn the world into a permanent nuclear winter? Im surprised at how serious people are at this which is good, but im also surprised no one has mentioned Deng yet.....
