evidence: The Korean Demilitarized Zone (DMZ) is a strip of land running across the Korean Peninsula that serves as a buffer zone between North Korea and South Korea. The DMZ is a de facto border barrier and divides the Korean Peninsula approximately in half. It roughly follows latitude 38°N (the 38th parallel), the original demarcation line between North Korea and South Korea at the end of World War II. The Demilitarized Zone incorporates territory on both sides of the cease-fire line as it existed at the end of the Korean War (1950-1953), and was created by pulling back the respective forces 1.2 miles along each side of the line. [...] The border between North and South Korea is one of the most heavily guarded stretches of land in the world. The DMZ, littered with scores of mines and barbed-wire fences, is nightmarishly difficult to cross, except the Joint Security Area (JSA). JSA is a special buffer zone inside what is known as the "truce village" of Panmunjom, about 35 miles north of Seoul. Every year, hundreds of thousands of people usually visit the JSA for a chance to see North Korean soldiers standing at attention just dozens of feet away and to officially step into North Korean territory inside a United Nations administered conference room that literally straddles the military border.
