This is a cross-post of an essay originally written for the Lowy Institute this week, available here.
This essay is the last round of a 2-month long debate between me and Van Jackson of Georgetown. Van wrote at the Diplomat; I wrote at the Interpreter. Here is part 1 (Van), part 2 (me), and part 3 (Van again). Van is a friend and way smarter than me. You should read his stuff.
Basically, I argue that if South Korea gets involved in the South China Sea flap, opposing China, then China will resume its relationship with North Korea. Right now that relationship is the coldest it has ever been. That is awesome. We really, really want this. The day China cuts off North Korea is the day the countdown to North Korea’s implosion begins.
Van argues South Korea could help get better Chinese behavior in the South China Sea. Mathematically, that is true; every little bit helps. But that help is small and the gains of a Sino-North Korean split are huge. Even if that split won’t happen soon, there is no way North Korea will collapse without it. So we have to do everything we can to groom Beijing’s alienation from Pyongyang. SK keeping quiet on the SCS, even when it agrees with the anti-Chinese coalition down there, is a necessary, albeit minor, cost.
Anyway, it’s a good debate. Judge for yourself after the jump.
