The problem:
North Korea has hundreds (thousands?) of artillery pieces pointed at Seoul - a major world-class city, and home to 1/4th of the South Korean population. Levelling Seoul would take about a half hour, and have repercussions across the globe.
NK also has nukes and the means to drop them on Japan. Japan also has nukes and delivery systems. Needless to say, the economic consequences would, er, get the world's attention.
JKI just has to give the word and Seoul and Tokyo disappear (at least in viable theory). The general plan seems to be: wait for the NK system to collapse entirely, which shouldn't take too long. Just wait 'em out.

That's are strategy now, but we've been waitng about 50 years. It does not not look like things are getting any better, only worse. Of course we've been waiting on Cuba for about 40 years. I guess it took about 60 years for the USSR to fall. Maybe we haven't waited long enough yet.
