Short and the usual doublespeak when it comes to N. Korea. "unacceptable behavior" "defies the will of the international community" "go to the UN to handle this".
Same thing that has brought us to N. Korea testing nukes. What can the UN do to stop them? Absolutely nothing.
In fairness, it wasn't all diplo-babble. The President did talk about America keeping its security commitments to S. Korea, which is an implied threat of force.
One would think this was anticipated and a course of action was in place. How can the world be so passive?
