North Korea says it has successfully conducted its first underground nuclear test, an action that has generated grave concern from the international community. News of the event dominated this morning's UN agenda, where the 15-member Security Council spent a brisk 30 minutes in universally condemning the test. President Bush responded by calling North Korea's actions "unacceptable" and deserving of "immediate response," vowing to hold Pyongpang "fully accountable." Similar statements of concern have been issued from spokespeople in South Korea, the UK, China, Japan and Australia. Guest host Diana Nyad explores the UN's response to what countries such as China are calling "flagrant and brazen" violations of international opinion.
