** ADVANCE FOR USE SUNDAY, OCT. 10, 2010 AND THEREAFTER ** This image shows a cover letter dated Aug. 20, 1953 to a plan for the atomic bombing of China, Manchuria and North Korea if hostilities resumed in Korea. It was sent by the Strategic Air Command to Air Force headquarters on Aug. 20, 1953, less than a month after an armistice was signed in Korea. Sixty years after the start of the Korean War, recently released declassified documents have helped fill in the history of U.S. nuclear threats against North Korea over the decades. (AP Photo) less
