North Korea has successfully, sort of, launched a long-range missile. We are outraged. We want more sanctions; we want to pressure them till they say uncle or collapse. We wonder how China could be so perfidious in failing to make Pyongyang behave. We find it morally odious to talk to a regime that spends for rockets and nukes but allows it people to starve and puts others in concentration camps. Only when they agree in advance that they will knuckle under will we talk to them.
