North Korea ended up launching their rocket on Wednesday, after weeks of rumors that the launch would be delayed. South Korea, Japan, and the US are looking to China to step up its involvement in the matter.
For whatever it's worth, China's official statement expressed "regret" for the launch--a term their spokesmen have never used before when referencing their neighbor's provocations. But they still have not clarified how such action is a violation of UN resolutions. And while these test launches indicate a possible path toward a nuclear warhead, so far it looks like the North Koreans do not have a nuclear weapon that is small enough for a missile to properly carry.
Look for more of these attention-grabbing events from the DPRK in 2013 as long as their food aid remains cut off from the West.
