North Korea and its Bottle Rockets

Is it just me, or does North Korea launch Taepodong missiles like they were 5 cent bottle rockets? They just finished launching 7 and they're suddenly planning for 5 more. They didn't even hit the cooler on the way back to their stash.

There isn't much the US can do in this situation besides pressure the Chinese and hope Beijing realizes that N. Korea creates more insecurity for Japan and the US than its own military build-up.
