Nuclear N. Korea a 'Grave Threat': Obama

A nuclear-armed North Korea poses a "grave threat" to the world and cannot achieve its own security by building illegal weapons, President Obama said today. With South Korea’s president at his side in the Rose Garden, Obama said they agreed that a new UN resolution seeking to halt North Korea's development of nuclear weapons and ballistic missile must be fully enforced.

Lee Myung-bak said he and Obama agreed that "under no circumstance are we going to allow North Korea to possess nuclear weapons." "Given the belligerent manner in which they are constantly threatening their neighbors," Obama said, "I don't think there's any question that that would be a destabilizing situation that would be a profound threat not only to United States security but to world security."
