At the end of 1951 and into 1952, the Korean War looked like World War I: Static front lines. A Main Line of Resistance (for both sides). A No Man’s Land in between. Basically the UN forces and the Communist forces manned outposts on the hills surrounding the lines of resistance and the war became a series of battles for control of these high ground outposts., with several changing hands many times. Eventually the peace talks resumed in Panmunjom and in July 1953 an armistice was signed. No peace treaty was ever signed. Both South and North Korea claim sovereignty over the entire Peninsula and the Demilitarized Zone (at the 38th Parallel where it all began) is the most heavily fortified border in the world.
