North Korea said today that it would use nuclear weapons in a "merciless offensive" if provoked, just two days after sentencing two American journalists to twelve years in a gulag-type prison labor camp. Guest host Sara Terry explores the motives behind North Korea's recent aggressive actions and whether the US should re-start negotiations or take a hard-line stance with the secretive communist power. Also, the first Guantanamo detainee is transferred to the US, and a victory for human rights activists in the Niger Delta.
