North Korea rattles sabers, demands attention, candy

[khagler]

If China conquered North Korea they'd be stuck sharing a border with the US, and avoiding that danger is the whole point of their propping up North Korea in the first place. Even when that danger goes away (either by South Korea declaring independence or by the inevitable collapse of the US empire) I can't see why they'd want to bother--it's better for them to just cut off support for North Korea and let it be South Korea's very expensive problem.
