Despite the failure of its attempted missile launch, North Korea's provocative action threatens regional security, violates international law and contravenes its own recent commitments. While this action is not surprising given North Korea's pattern of aggressive behavior, any missile activity by North Korea is of concern to the international community. The United States remains vigilant in the face of North Korean provocations, and is fully committed to the security our allies in the region.
The President has been clear that he is prepared to engage constructively with North Korea. However, he has also insisted that North Korea live up to its own commitments, adhere to its international obligations and deal peacefully with its neighbors.
North Korea is only further isolating itself by engaging in provocative acts, and is wasting its money on weapons and propaganda displays while the North Korean people go hungry. North Korea's long-standing development of missiles and pursuit of nuclear weapons have not brought it security – and never will. North Korea will only show strength and find security by abiding by international law, living up to its obligations, and by working to feed its citizens, to educate its children, and to win the trust of its neighbors.
