On the basis of the sources from the National Archives in Washington, the author deals with the
research work on the internal Yugoslav situation between 1942 and 1945, made by the Research &
Analysis Department of the Office of Strategic Services. The Department was receiving the reports
from the American missions at the Chetnik and Partisan Headquarters, of General Draža Mihailović
and Josip Broz Tito, and kept contacts with a number of Yugoslav politicians in exile and emigrant
organizations. The analysts, the most important of whom were two brothers, Dr. Alexander and Dr.
Wayne Vucinich, produced a series of incisive analyses of the military and political situation and trends
in the occupied Yugoslavia. However brilliant, these analyses only had a gradual and limited influence
on the US government policy towards Yugoslavia.
