President Bill Clinton once called North Korea, "the most dangerous place on earth."
What separates it from the South is the DMZ, the two-and-a-half mile wide demilitarized Zone, with large contingents of battle-ready troops on both sides.
About one-quarter the size of Yellowstone park, but heavily mined and riddled with tunnels from the North, the DMZ is such a no man's land that it has become a refuge for endangered plant and animal species. Some activists want to turn it into a nature preserve, but defense analysts like Bruce Bennett say that it's still a theater for a possible war, and more likely, a highway for refugees and troops if North Korea collapses.
