Gaddis's own The United States and the Origins of the Cold War, 1941-1947 had been broadly 'orthodox'. Such basically benign interpretations of US foreign policy were challenged, especially in the 1960s and 1970s, by writers who portrayed it as driven by the search for economic profit and expansion abroad, and as using the fear of communism to effect repressive changes in US domestic society and politics. Besides its holdings of 'primary documents central to US foreign and military policy since 1945', the Archive has acquired collections from other countries. Moreover, many former Cold War figures, Russian as well as American, happily talked to interviewers and relived their experiences at the many historical conferences organised during the 1990s. Also devoted to the assembly and diffusion of documents and historical studies based on them, but focussing primarily on those from the communist world, is the 'Cold War International History Project'.
