Cathy correctly identifies the demarcation line between North and South Korea as the 38th Parallel, something that has remained the dividing line between the two countries since 1945 when Japan lost control of the Korean peninsula to U.S. and Soviet forces at the end of WWII. Because the U.S. and the U.S.S.R. could not agree on how the peninsula should be managed, they arbitrarily selected this halfway point to separate North from South.
