What is the DMZ?

The Demilitarized Zone in Korea is the border in between the two international locations which is intensely guarded and strictly enforced on the two sides.Korea is a country that is nonetheless at war simply because they never signed a peace treaty.Often spies and defectors do manage to cross the border undetected but these times are few and significantly in between.
