I certainly dont know the answer...and don't want to see Seoul take the brunt of any kind of military action, that said, "coming home" is NOT an option, no more than sitting idly by for 10 years and watching Nazi Germany arm up was an "answer"........NK is a major threat and they need to be reigned in BEFORE they launch a nuke at "some" one, be it Seoul or Los Angeles.  NK is EVERYONE's problem......you are misinformed to think otherwise.
