Right, I forgot how devastating even a misfire was!! As you said, even a crudely made nuclear weapon is still effective at causing unnecessary levels of destruction. I think I wanted to downplay this "threat" since both Korea's are connected, the fallout would affect themselves? Unless they have suicidal tendencies (a characteristic not found in dictators) they won't be going the nuclear option with their neighbour literally looking distance. Then again we have Israel going at it and they have a nuclear arsenal...
