Most people don’t realise that the Korean War, which began on the 25th of June 1950 with the invasion of South Korea by Communist North Korea, did not end with the signing of an armistice on the 27th July 1953. The armistice only allowed for a ceasefire, the creation of a Demilitarised Zone, and the return of prisoners of war. So technically North and South Korea have never signed a peace treaty, and are still at war.
