(CNN) - North Korea on Wednesday blamed South Korea for driving them "to the brink of war," a day after the North shelled a South Korean island and killed four people. South Korea provoked the shelling of Yeonpyeong Island by holding a military drill off their shared coast in the Yellow Sea, North Korea said. Pyongyang made the accusation through its state media, referring to a military drill that Seoul holds every year.
Today on American Morning, Victor Cha, a former NSC Asia affairs advisor and senior advisor and Korea Chair, Center for Strategic and International Studies, explains the conflict.
AM’s John Roberts asks Cha if the conflict could turn to all out war, and how the United States should respond.
