FILE - This July 24, 1953 black-and-white file photo shows the completed armistice hall in Panmunjom stands ready for the signing of the Korean armistice. This is the north entrance through which the North Korean and Chinese delegations will enter. Peace doves decorate the building over every doorway. Sixty years after it finished fighting in Korea, the U.S. is still struggling with two legacies that are reminders of the costs -- political, military and human -- that war can impose on the generations that follow. The first is the leading role that America still is committed to playing in defending South Korea should the 1950-53 Korean War re-ignite. (AP Photo, File)
