The line between North and South Korea is one of the most nerve-wracking borders on Earth. Although the Korean War is technically over for the U.S., the North and South are still very much at war — maintaining guard towers and thousands of troops facing each other, waiting for the next invasion.
The buffer zone created by the 1953 Armistice between North and South is called the de-militarized zone (DMZ), although there's a huge military presence. This border is filled with fencing, mines, and troops on both sides with itchy trigger fingers.
This relic of the Cold War has seen plenty of very hot engagements: Over 300 American and South Korean, and almost 400 North Korean soldiers were killed in firefights in 1969, and there are numerous instances of infiltrators from the North being scared back only by the sound of warning shots.
The Korean War may seem like it's over, but the armistice of 1953 only brought on a stalemate and both North and South are still at war.
At the 38th parallel lies the de-militarized zone (DMZ), with troops stationed along both sides in case the other decides to attack.
And attacks have happened many times. North Korean soldiers killed two US Army officers here in 1976 at "The Bridge of No Return"— named because captured NK prisoners hardly ever wished to go back home.
