<P> Leaflets could be dropped from aircraft to populations in locations unreachable by other means; for example, when the population was afraid or unable to listen to foreign radio broadcasts . As such, the United States extensively used leaflets to convey short informational tidbits . In fact, one squadron of B - 17 bombers was entirely dedicated to this purpose . Leaflets were also used against enemy forces, providing "safe conduct passes" that enemy troops could use to surrender as well as counterfeit ration books, stamps and currency . The very scale of the leaflet operations had its effect on enemy morale, showing that the Allied armament industry was so productive that planes could be diverted for this purpose . </P> <P> The use of leaflets against Japanese troops was of little effect . Many civilians in Okinawa discounted pamphlets declaring that prisoners would not be harmed . By the time American planes could reach the Japanese home islands, the leaflets had improved, providing "advance notice" of bombings ensured that the leaflets were read avidly despite prohibitions . These pamphlets declared they had no wish to harm civilians, only the military installations, and that the bombings could be stopped by demanding new leaders who would end the war . After the atomic attacks, more pamphlets were dropped, warning that the Americans had an even more powerful explosive at their disposal . When the Japanese government subsequently offered to surrender, the U.S. continued to drop pamphlets, telling the Japanese people of their government's offer and that they had a right to know the terms . </P> <P> The American Historical Association's G.I. Roundtable Series of pamphlets was used to ease transition to the post-war world . </P> <P> In the United States, radio was so widely used for propaganda that it greatly exceeded the use of other media that was typically used against other nations . President Roosevelt's fireside chats are an excellent example of this use of radio . In February 1942, Norman Corwin's This is War series was broadcast throughout the country and, by shortwave, throughout the world . Other significant uses of radio overseas includes messages to the Italian Navy, which persuaded it to surrender . CBS Radio's counterpropaganda series Our Secret Weapon (1942--43), featuring writer Rex Stout representing Freedom House, monitored Axis shortwave radio propaganda broadcasts and rebutted the most entertaining lies of the week . </P>
