Why Not North Korea?

I’m not exactly breaking news here, since Instapundit and Andrew Sullivan have already linked to this, but Orson Scott Card’s analysis of the North Korea situation is the best I’ve seen. If you want three reasons why we’re not at war with North Korea, they would be, in order:
1. China
2. North Korea can nuke Seoul, and
3. We haven’t spent the past year building international support.
Card nails the China question. John McCain also has a fine piece in the Weekly Standard, with less emphasis on China and calling for some of the more aggressive moves that Card seems skeptical of. McCain is right that negotiating with the North Koreans is nonsense, but he doesn’t really address the issue of whether we should be negotiating with China.
