This volume throws important new light upon a pivotal period of transition in the Anglo-American relationship and sets the stage for its equally dramatic transformation during and after the Second World War. Based upon extensive research in previously unpublished archival material on both sides of the Atlantic, for the first time this book offers a detailed and comprehensive analysis of the war debt problem from its origins at the end of the First World War until its final removal with the launch of Roosevelt’s Lend-Lease programme in 1940-41. This work will be of great interest to diplomats and journalists, as well as to students and scholars of political, diplomatic, economic and international history.
