Explores Anglo-American economic diplomacy in South America during the Second World War. Thomas Mills explores Anglo-American relations in the previously neglected region of South America during the Second World War to add a new dimension to our understanding of the two powers. He shows how these relations followed a very different pattern to the high-level discussions concerning the economic shape of the post-war world that were going on at the same time. In this way, he highlights the need for a more nuanced understanding of the broader process of Anglo-American economic diplomacy. Based on extensive archival research and a thorough knowledge of the secondary literature, this is a major addition to the study of Anglo-American relations in the 20th century.
