North, South Korea fire off dueling missile-launch videos
First came the missiles. Then the videos. North Korea (left) threw down the gauntlet Tuesday with a test launch of its first intercontinental ballistic missile. South Korea and the United States responded Wednesday with a joint missile-firing drill (right) into waters off the Korean coast. In this footage North Korea shows the same launch from seven angles. South Korea and U.S. answer with multiple launches, some in slow motion.
