While in Seoul on business, my local partners took for a day trip to the Demilitarized Zone (DMZ) at Panmunjom between South and North Korea. It’s the most militarized border on earth and the world’s most dangerous border.    Centred on the DMZ is the Military Demarcation Line (MDL). This is the actual political border. Adjacent is the Joint Security Area (JSA) and related gift shops (yes).  It’s the Disneyland of politics.
