I think this would be a big effort and very costly.  I favor the use of tactical nuclear weapons and turning North Korea in to a radioactive parking lot for Seoul.  The US has a lot of nukes and really needs to test them out.  Need to teach the rest of the world (China and Russia) the world policeman is back and not in a good mood.  Collateral damage is not a problem for this new President.  Killing a few million North Koreans a problem?  Not if it is going to cost the USA New York, Chicago, Los Angeles or Honolulu.

Like a scene from a Walking Tall movie, the crook surrenders to Sheriff Pusser after running out of bullets. Crook then says that when he gets out on bail, he will come back to kill Pusser and his family.  Pusser then shoots and kills the crook and says, "I believe you".  So Lil' Kim, we believe you. We will just kill you and your whole country because we are not stupid enough to give you time to get a nuke.  The armistice is over.
