just a lie as one solution by the government toward the US leaflet strategy. It was called the "atrocity stories" strategy that emphasizing cruelty of people in enemy countries, and the strategy was used well in other countries after World War 1. The effect of US leaflets can be seen during the controversy of whether Japan should surrender or continue resistance. Because the leaflets might cause the riot of soldiers who read it, the Japanese emperor decided to surrender. After World War II Even though leaflet propaganda has been an effective "weapon", its use has been on a decline. This decline is a result of the advance of satellite, television, and radio technology. Six billion leaflets were dropped in Western Europe and 40 million leaflets dropped by the United States Army Air Forces over Japan in 1945 during World War II. One billion were used during the Korean War while only 31 million were used in the Iraq War. Other conflicts where leaflet propaganda has been used are Vietnam, Afghanistan (both during the Soviet and more recent NATO invasions), and the Gulf War. Coalition forces dropped pamphlets encouraging Iraqi Army troops not to fight during the first Gulf War, which contributed to eighty-seven thousand Iraqi troops surrendering in 1991. During the 2011 enforcement of a NATO No-Fly Zone over Libya, the Royal Canadian Air Force and U.S. Air Force used C-130J Hercules and CP-140 Aurora aircraft to broadcast radio signals and drop leaflets over Gaddafi controlled areas. The messages predominantly asked Muammar Gaddafi's troops to return to their families and homes for their safety, but also included the message: "The forces of the Gaddafi regime are violating United Nations Resolution 1973." Some messages called on the troops to stop hostilities and not to harm their compatriots, while other messages broadcast by NATO included female voices asking Gaddafi's forces to "stop killing children". Leaflet propaganda was also used in the Syrian civil war to deter possible ISIS recruits from joining in 2015. Means of delivery Releasing the leaflets can be as simple as having one or more of the aircraft's crew throw bundles of paper from an open hatchway. A more sophisticated method is the leaflet bomb: a bomb-shaped but non-explosive container that drops from the aircraft and opens in mid-air to disperse leaflets – up to tens of thousands of leaflets per "bomb". U.S. leaflet bombs include the PDU-5B dispenser
