Another piece on the China-North Korea relationship.
Just a quick thought on this and on the broader question. There are some pretty clear reasons for wanting to do something about the current regime in North Korea. But when people discuss what should happen, the common refrain seems to be treating China like a teenager that wants oh so badly to drive mom and dad's car, but just hasn't proven himself yet. I'm fairly certain this article explicitly mentions the notion that the US has tried to get China to feel like it has some "responsibility" for taking care of this issue, and I think this is part of the problem.
