I'll preface this by saying I served in Korea for 3 1/2 years, having left in late 2007, and am pretty familiar with the situation there.
Really, things haven't gotten so bad. They are arguably better, and more stable, than they have ever been (that doesn't make it a good situation, but it used to be far worse). Consider that in the 1970's and 80's both countries were actively trying to assassinate each other's leaders, North Korea was blowing up jet liners and murdering American military officers and kidnapping Japanese schoolgirls, and both sides were always a hair away from all out war. Right now, in spite of all the missile business, things are still relatively quiet.
A few points about this article:
- South Korea is more than capable of defending itself. In fact, the U.S. is still planning on turning over full operational control in the next couple of years, and will be relegated to more of a support role. The U.S. would likely provide South Korea with some of the things it lacks (stronger air power, intelligence gathering, naval strength), but the ground war would probably be primarily South Korean. The U.S. isn't going to withdraw all 29,000 Soldiers, but the makeup of those Soldiers has already changed drastically (far fewer combat troops).
- The U.S. could not seriously contemplate attacking North Korea with South Korea's support. 15-20 years ago, maybe. Now? No way. And South Korea has little to gain and everything to lose from that kind of move. Attacking North Korea is not a realistic option, even in a limited fashion.
- I have no idea who would ever claim that "Kim would do nothing" if attacked, so I'm not sure what the author is arguing against there.
- North Korea has never really been a U.S. issue, except that it is an issue of two of our strongest allies, Japan and South Korea. The U.S. has just been in the position to lead since neither Japan nor South Korea have been particularly assertive, politically, in the past few decades. Either way, though, I would certainly hope we'd continue to support our allies.
- I agree overall that restraint is the way to go. Like it or not, North Korea is, basically, able to hold South Korea hostage. It can't win a war, but it can kill hundreds of thousands, if not millions of people in the process of losing. That's enough reason to not attack them, as distasteful as it may be.
