The Introduction explains that veterans returned to Việt Nam in search of resolution, or peace, in their personal relationships with the war. This search manifested in nostalgia for “Vietnam,” with returnees acting as a diasporic community forged in war. While many returnees found a measure of peace upon return, they were also challenged by the erasure of their wartime presence. Veterans drew on wartime memories and performed nostalgic practices to recapture their sense of belonging in Việt Nam. Outlining three distinct eras of returnees, this chapter shows how a comparative, transnational perspective reveals stark differences in American and Australian war memories, narratives, and imaginings of “Vietnam.” This chapter presents a review of the existing scholarship on the topic of returning veterans, situating the book in broader literature on the war and its legacies; explains the book’s oral history methodology and analytic approach; and outlines the broader structure of the book.
