    Iva Toguri D'Aquino, aka "Tokyo Rose"
    mug shot, Sugamo Prison, 07 Mar 46

    Tokyo Rose was a generic name given by Allied forces in the South Pacific during WWII to any of approximately a dozen English-speaking female broadcasters of Japanese propaganda. The name is most strongly associated with Iva Toguri D'Aquino, an American citizen born to Japanese immigrants. D'Aquino broadcast as "Orphan Ann" during the 15-20 minute DJ segment of the 75-minute program The Zero Hour on Radio Tokyo (NHK). The program consisted of propaganda-tinged skits and slanted news reports as well as popular American music.

    The intent of these broadcasts was to disrupt the morale of Allied forces listening to the broadcast. American servicemen in the Pacific often listened to the propaganda broadcasts to get a sense, by reading between the lines, of the effect of their military actions. Farther from the action, stories circulated that Tokyo Rose could be unnervingly accurate, naming units and even individual servicemen. The name "Tokyo Rose" in the context of these broadcasts first appeared in US newspapers in 1943.

    When the war ended, the US military detained Toguri for a year before releasing her for lack of evidence. Department of Justice officials agreed that her broadcasts were "innocuous." But when Toguri tried to return to the US, a popular uproar ensued because Walter Winchell, the powerful broadcast personality, and the American Legion lobbied relentlessly for a trial, prompting the Federal Bureau of Investigation to renew its investigation of Toguri's wartime activities. Her 1949 trial resulted in a conviction on one of eight counts of treason.

    In 1974, investigative journalists found that key witnesses claimed they were forced to lie during testimony. Toguri was pardoned by US President Gerald Ford in 1977.

    Toguri's advocates have long argued that other announcers better suited the legend. These include the American Ruth Hayakawa (who substituted for Iva on weekends), Canadian June Suyama ("The Nightingale of Nanking"), who also broadcast on Radio Tokyo, and Myrtle Lipton ("Little Margie") who broadcast from Japanese-controlled Radio Manila. However, during the war, journalists and officials with the US Foreign Broadcast Information Service identified Toguri's "Orphan Ann" as the woman "most servicemen seem to refer to when they speak of Tokyo Rose" but characterized the "legends" of clairvoyance that "piled up about 'Tokyo Rose'" as "apocryphal."

    George C Marshall

    Marshall was an American military leader, Chief of Staff of the Army, Secretary of State and the third Secretary of Defense.

    Once noted as the "organizer of victory" by Winston Churchill for his leadership of the Allied victory in World War II, Marshall served as the United States Army Chief of Staff during the war and as the chief military adviser to President Franklin D Roosevelt.

    As Secretary of State, his name was given to the Marshall Plan, for which he was awarded the Nobel Peace Prize in 1953.

    The labeling was deemed necessary when Congress became concerned that the Soviet Union was taking credit for the poorly-marked US foreign aid donations to European countries. The slogan was translated into the languages of the recipient countries. The slogan became obsolete when military aid was added to the economic program and when some Near East and Asian countries became aid recipients under President Truman's Point IV Program.

    In 1951, the slogan was changed to "Strength for the Free World from the United States of America."
