Even in former days, Korea was known as the 'hermit kingdom' for its stubborn resistance to outsiders. And if you wanted to create a totally isolated and hermetic society, northern Korea in the years after the 1953 'armistice' would have been the place to start. It was bounded on two sides by the sea, and to the south by the impregnable and uncrossable DMZ, which divided it from South Korea. Its northern frontier consisted of a long stretch of China and a short stretch of Siberia; in other words its only contiguous neighbors were Mao and Stalin. (The next-nearest neighbor was Japan, historic enemy of the Koreans and the cruel colonial occupier until 1945.) Add to that the fact that almost every work of man had been reduced to shards by the Korean War. Air-force general Curtis LeMay later boasted that 'we burned down town in North Korea,' and that he grounded his bombers only when there were no more targets to hit anywhere north of the 38th parallel. Pyongyang was an ashen moonscape. It was Year Zero. Kim Il Sung could create a laboratory, with controlled conditions, where he alone would be the engineer of the human soul.
And now life has become the future. Every moment of your life is lived for the future-you go to high school so you can go to college so you can get a good job so you can get a nice house so you can't afford to send your kids to college so they can get a good job so they can get a nice house so they can afford to send their kids to college.
