FILE - In this Wednesday, April 10, 2013 file photo, young North Korean workers and students climb stairs to the base of bronze statues of the late leaders Kim Il Sung and Kim Jong Il during an event to pledge loyalty to the country in Pyongyang, North Korea. Enemy capitals, North Korea said, will be turned “into a sea of fire.” North Korea's first strikes will be “a signal flare marking the start of a holy war.” Pyongyang's nuclear arsenal is “mounted on launch pads, aimed at the windpipe of our enemies.” And it's not all talk. The profoundly isolated, totalitarian nation has launched two rockets over the past year. But there is also a logic behind North Korea's behavior, a logic steeped in internal politics, one family's fear of losing control and the ways that a weak, poverty-wracked nation can extract concessions from some of the world's most fearsome military powers.
