South Korea says it got an apology. North Korea says its archrival learned a “serious lesson”. 

A top North Korean decision-making body issued a pointed warning today, saying that nuclear weapons are “the nation’s life” and will not be traded even for “billions of dollars”.

North Korea has ordered its people to be ready for a protracted war against the United States, issuing guidelines on evacuating to underground bunkers with weapons, food and portraits of leader Kim Jong Il.
