FILE - In this June 25, 2013 file photo, North Koreans chant slogans on Kim Il Sung Square in Pyongyang, North Korea as they hold an anti-U.S. demonstration during the 63rd anniversary of the outbreak of the three-year Korean War, from 1950 to 1953. The poster reads "Meet Force with Force," top, "National Missile Defense System. A Strong Stand," center, and "Meet Hardliners with Harder Attitudes," bottom. North Korea’s propaganda machine is churning out near-daily diatribes against the United States and South Korea for a series of soon-to-start military maneuvers, warning nuclear war could be imminent and saying it will take dramatic action of its own if further provoked.
