Between 1939-1941, from the time that Germany invaded Poland until Japan attacked Pearl Harbor, Americans engaged in a debate as intense as any in U.S. history. In Storm on the Horizon, prominent historian Justus D. Doenecke analyzes the personalities, leading action groups, and major congressional debates surrounding the decision to participate in World War II. Doenecke is the first scholar to place the anti-interventionist movement in a wider framework, by focusing on its underlying military, economic, and geopolitical assumptions. Doenecke addresses key questions such as: how did the anti-interventionists perceive the ideology, armed potential, and territorial aspirations of Germany, the British Empire, Japan, and the Soviet Union? To what degree did they envision Nazi Germany as a bulwark against the Soviet Union? What role would the U.S. play in a world increasingly composed of competing economic blocs and military alliances? Storm on the Horizon is certain to become the standard study of this tumultuous time and will require readers to reevaluate their understanding of the United States entry into World War II.

"Like Doenecke's previous books, this work demonstrates solid scholarship." - Library Journal

"Thanks to Doenecke's meticulous research, Storm on the Horizon is likely to become the standard work on the noninterventionist movement of 1939–1941. More importantly, it is to be hoped that it will reopen scholarly discussion about a vein of American opinion that has been too quickly dismissed." - H-Diplo Reviews

"This book should be read by serious students of U.S. political and diplomatic history of the 1930s and '40s. Recommended for graduate students, faculty, and all research libraries." - CHOICE

"A compelling and informative history of how America became entangled in Europe's political and military struggles prior to the Japanese bombing of Pearl Harbor. Doenecke combines painstaking and meticulous historical research with perceptive insights and an ability to engage the reader's total attention. Storm on the Horizon is particularly recommended reading for students of 20th Century American history, World War II, and the role of the Roosevelt administration in dealing with American isolationist sentiments." - The Bookwatch

"Storm on the Horizon is marked by Doenecke's unsurpassed familiarity with the relevant archives and by his rare and refreshing objectivity. . . . Also indicative of the richness of the book are the frequent fascinating tidbits Doenecke serves up. . . . Storm On the Horizon is a work of outstanding scholarship. Sudents of the greatest anitwar movement in American history, revisionists and nonrevisionists alike, are permanently in Justus Doenecke's debt." - The Independent Review: A Journal of Political Economy

"Storm on the Horizon shows extraordinarily wide and deep research." - Intelligence and National Security

"The book is thoroughly researched, exhaustively documented, and even-handed in its approach." - Journal of American History

"A treasure of source material." - American Historical Review

"A raconteur of non-interventionist lore, Doenecke unearths a staggering number of sources, and sufficient biographies, stories, and vignettes to make one wonder if he ever sleeps. Doenecke's major contribution is placing the debate on U.S. intervention within an unfolding, day-by-day context." - International History Review

"For years, Justus Doenecke has challenged negative conclusions about the anti-interventionists. Storm on the Horizon is his latest and most comprehensive work on these individuals. It is also his most impressive such effort, the first major and full study of the anti-interventionists since Wayne Cole's 1983 Roosevelt and the Isolationists, and a worthy recipient of the Herbert Hoover Book Award of the Hoover Presidential Library Association for 2000." - Diplomatic History
