A report written in 1974 describing the formation, functions, and activities of the Joint Intelligence Sub-Committee (JIC) from its formation in 1936 to the outbreak of the Second World War. The report describes the composition of the original JIC, defining its duties and describing the personnel appointed to the JIC. The report proceeds to describe the activities of the JIC between 1936 and 1939, in particular the JIC's responses to the Italian invasion of Ethiopia, the Second Sino-Japanese War, the Spanish Civil War, and Hitler’s aggressive foreign policy in central Europe. The report concludes that while the JIC conducted intelligence assessments, its impact on policy making before the Second World War was marginal.
