We're all watching and waiting, hoping that once again N. Korea is just crying wolf. I haven't heard anyone get all gung ho to go to war with N. Korea. Conservatives, liberals, moderates, anarchists, socialists, seeing eye dog trainers, we all want N. Korea to stop threatening us and mind their own business.
Again, you're way off base thinking that there would be ANY U.S. nation building in N. Korea. First, if war did break out it wouldn't be "that kind" of war. The U.S. wouldn't be able to show off our toys while remaining completely unscathed. Hundreds of thousands of people in Seoul would DIE in the opening hours of any full-scale conflict. N. Korea doesn't have to do anything but pull the trigger to launch a massive barrage of conventional artillery at Seoul. I don't think you get that that is a real stumbling block here. The U.S. is not, I repeat, is not going to intentionally set things off and have that blood on our hands. We would not be able to stop it from happening. The opening act of a full-scale war on the Korean peninsula would most likely provide the single deadliest hour of warfare in human history.
So stop acting like this is a conservative plot to engage in the United State's favorite past time of nation building. Unfortunately (fortunately) this situation doesn't provide for that opportunity. N. Korea borders China. S. Korea has an understandable notion that N. Korea is just a separated part of their same country, their same people, with a common history and common foes. S. Korea is fully capable of taking on the nation building role in N. Korea if the regime falls. If they don't want the job the next in line would be China if the two Koreas remain separate.
I don't think Kim Jong Un intends for this thing to go hot. That's awesome. However, when big threats are being thrown around and tensions are high it is very possible that a slip-up or misinterpretation on the part of any of the half-dozen players in this could lead to an uncontrolled chain of events. If that happens it is likely hundreds of thousands if not millions of people will die. That's why this concerns me.
In situations like this I'm able to put the liberal vs conservative BS aside. I'm sorry you lack that ability, Thriller.
