PAJU, SOUTH KOREA - FEBRUARY 15: A South Korean looks in the direction of North Korea near the demilitarized zone (DMZ) at the Dora Observation Post on February 15, 2005 in Paju, South Korea. South Korea has proposed high-level military talks with North Korea, just as tensions on the divided Korean Peninsula reach new heights over the North's announcement last week that it has built nuclear weapons.
