De Witt Clinton Poole,the foreign nationalities branch and political intelligence

The Foreign Nationalities Branch of the Office of Strategic Services served as an important source of political intelligence for the Roosevelt administration during World War II. The philosophy of the Branch's most influential director, DeWitt Clinton Poole, and his organization's work among Yugoslav‐Americans, illustrates the concerns that ethnic politics generated in the United States, as well as appreciation of the role that ethnics could play in psychological warfare and postwar anti‐Soviet propaganda.
