Like the Japanese attack on Pearl Harbor which some historians say was not intended as a surprise attack, a Korean attack would probably result from a mistake in communication. 

I'm sure their commercial and diplomatic corps in govt have more international experience like the Japanese navy had in WWII and oppose such aggression. 

But the Koreans hawks are in charge and the diplomatic and commercial interests should be careful of what they say for their own personal safety.

The American military should know their missile accuracy by now by knowing where the Koreans deployed to retrieve theic missile. Can they really hit such a small target as Hawaii thousands of miles away?
