North Korea's attempt to launch its first spy satellite into space failed, dealing a setback to leader Kim Jong Un's military ambitions and his efforts to increase pressure on the United States and South Korea. After quickly admitting the failure, North Korea vowed to conduct a second launch after identifying the cause of the rocket's failure. The launch violated U.N. Security Council resolutions prohibiting North Korea from using ballistic technology. The failed launch raises concerns about North Korea's missile technology and progress toward developing functioning nuclear missiles, and the international community strongly condemned the launch.
