Jaclyn Granick's meticulous and compelling monograph is an important contribution to contemporary Jewish history and to the international history of World War I and the postwar era. Adding substantially to Zosa Szajkowski's earlier studies, Granick, drawing on her extensive archival research, not only places the overseas work led by American Jews in a very large diplomatic, political, social, and economic framework but also elucidates its challenges, accomplishments, and uniqueness.
