More arithmetic for you: The Rand Corporation estimates the cost of Korean reunification at $50 billion, Credit Suisse insists $1.5 trillion is the expense, and Stanford fellow Peter M. Beck posits an alarmist $2-$5 trillion. Question: Who's got that kind of cash? Answer: North Korean mines. 360 minerals are sequestered in the Hermit Kingdom's caves, many trapped by flooding and NK's [North Korea's] appalling infrastructure. Billions of tons of coal, iron, zinc, magnesite, nickel, uranium, tungsten, phosphate, graphite, gold, silver, mercury, sulfur, limestone, copper, manganese, molybdenum... worth an estimated $2-$6 trillion (Goldman Sach's figure is $2.5 trillion). Reunification could be entirely paid for by these mines, perhaps with change left over.
