Striking North Korea?   The United States has been trying to starve them out for the last 60 years...  Hasn't worked.    Pacification of a population or otherwise know as CORDS (Civil Operations and Revolutionary Development Support) was an pacification program of the population of  Vietnam.  The program was created on 9 May 1967, and included military and civilian components of both governments.  As you fail to mention, this program never worked out and was an utter failure.   In fact this approach  has never worked in any war the US has been in.   Yet, you are under the misguided opinion it will work, while offering no proof. 

Many often fail to understand this WAR is NOT over and it was started by the US and Russians after WWII.    We divided this country up for reasons I and many others will  never understand...    North Korea military government wants to destroy the US.  Now you suggest we should wait until one of our cites is glowing before we strike?    Which city?
