Of course 0 would never even contemplate such a thing, but hypothetically-speaking:
Do you think we should invade the DPRK already? Are we tired of listening to this shit and trying to figure out what Mr.Kim will do?
South Korea has had a reunification plan for years, so I could imagine implementing it on the fly wouldn't be too hard. Invading would be hard, but if SK & Japan bore the brunt of the invading force (with the USAF & Navy doing the bombing), would we be able to do it in a week or two? It wouldn't be an Iraq with a large insurgency...it would be a cross between the liberation of Kuwait and the reunification of Germany, in my opinion.
