USA HISTORY

Detailed explanation-1: -The DMZ, which runs for about 150 miles (240 km), constitutes the 1953 military cease-fire line and roughly follows latitude 38° N (the 38th parallel) from the mouth of the Han River on the west coast of the Korean peninsula to a little south of the North Korean town of Kosŏng on the east coast.

Detailed explanation-2: -The Korean Demilitarized Zone (Korean: ) is a strip of land running across the Korean Peninsula near the 38th parallel north. The demilitarized zone (DMZ) is a border barrier that divides the peninsula roughly in half.

Detailed explanation-3: -After the Armistice agreement was signed on July 27, 1953, a new line was established to separate North Korea and South Korea. This Military Demarcation Line is surrounded by a Demilitarized Zone. The demarcation line crosses the 38th parallel, from the southwest to the northeast.

Detailed explanation-4: -Since U.S. policy toward Korea during World War II had aimed to prevent any single power’s domination of Korea, it may be reasonably concluded that the principal reason for the division was to stop the Soviet advance south of the 38th parallel.
