The tour bus bounces along one of North Korea's potholed roads, pop music blasting out over the speakers. It's a catchy tune and even though none of the tourists can understand the lyrics, a few are tapping their feet to the beat. The hit song, "Without a Break," is by Moranbong, by far North Korea's most popular band. The driver is clearly a fan and plays the DVD several times a day. Most tourists are busy looking out the window and pay little attention to the video screened at the front of the bus. They don't notice the nuclear missile being launched behind the all-girl band, nor do they see it smash into our little blue planet, blowing up the Earth. "'Without a Break' is about the nuclear destruction of the U.S.," says Australian Mark Freeman, who has visited North Korea four times.
