America doesn't need to be involved at all. Once North Korea gives South Korea a good enough excuse to make it politically viable, the south will totally overrun the north and rebuild it themselves. In fact, I would be willing to bet that South Korea and Japan would have some talks and become better friends, possibly doing away with some of the historical Japan-Korea animosity. Everyone wins except for the Kims.
I'd love that. But like China, both Korean governments has been pushing Anti-Japan propaganda so hard, I think it will take at the very least another generation for the relationships to really start healing. It reminds me of the Middle East. What your ancestor did to my ancestor, and that land used to be ours, and all that. Politicians who push these agendas really should be shot, and I mean that. Go on youtube sometime, and see all the impressionable kids eating the propaganda up, being a complete political puppet/tool. It's quite amusing & depressing. Not one(OK, maybe one, mine) post on there will be about how we should make effort to nicer neighbors. They are all pretty much about we want everybody in your country dead, because we just hate you. What a relief reading the posts on gtplanet!

South Korea could beat back North Korea with barely any outside help on our part. And outside help would certainly come, from almost everyone, if North Korea decided to invade again.
This.
As everyone pointed out, I wouldn't even take BBC's military balance chart into much consideration. Training, equipment, they are all suspect at best on the North Korean side. And I still believe that North Korean Army would collapse faster than the Iraqi Military did in '03. North Korea has controlled their people strictly with fear. Anyone who wouldn't go along were either imprisoned(opposite of the politically correct kinds), or killed. Yeah, I think they'll make efforts pretending to love Kim Jong-il. On top of that, they've been starving. South Korean Military on the other hand, they'd be willing to do anything to protect their way of life. No contest, all around.
...the US has Japan, with the most advanced and best-equipped military on the face of the Earth on a leash. All it needs is NK to rattle a short range missile in Tokyo's direction and Japan can turn the place into ash so sterile that life will never set foot on it again.
They are one of the better military forces out there, but nobody comes near the Americans in this game. Russians are making a comeback, Chinese military is growing as rapidly as their economy has. JSDF possesses
newer tech that U.S. allows, but they still aren't allowed to arm themselves with the
baddest in most department, most notably & probably most recently the F-22 Raptor. The U.S. didnt' think JSDF was capable of protecting the top-secret stuff on Raptor, and I don't blame them. JMSDF sure were loose in that department with the Aegis technology(minor leak).
JSDF has nice funding, very well trained troops, better than up-to-date equipment, but I'm pretty sure they wouldn't rate Top-5 in the world. In Asia, maybe second or third, I don't know how much the Russians have rebuilt in the region.
