I am talking REAL world where it is kill or be killed, not what somebody wants!
You are talking about your military fan boy fantasies of the United States killing a million North Koreans- not the real world.
There is no need for us to murder millions of North Koreans- if at some point we need to take action then, then we will take action.
We are not actually at war with NK- as we were with Japan. Nor is NK currently an actual threat to the United States.
Nor is NK Iraq- North Korea is sitting a few miles from millions of South Koreans(and thousands of Americans), with Japanese within range of NK missiles.
Remember- the main reason for NK's nuclear arsenal is to prevent an attempt at regime change in NK. Attacking NK would certainly lead to NK attempting to use nukes against the U.S. or our allies- and that could be as simple as sending a NK submarine to Tokyo harbor and detonating a nuke in the sub.
Why are you in such a rush for the United States to kill North Koreans?
