Storm on the Horizon is the most objective, comprehensive, and authoritative account of isolationism in the great debate before Pearl Harbor. In view of today's controversy about 'unilateralism,' there is all the more reason to take a fresh look at the unilateralists of 1939–1941.

Arthur Schlesinger Jr.

This exhaustive, penetrating study should demonstrate once and for all that FDR's foreign policy opponents prior to Pearl Harbor were not simply 'illustrious dunderheads' or ostriches blind to international dangers. As prophetic critics of both the imperial presidency and unrestrained globalism, Doenecke's noninterventionists may have lost the 'great debate' over U.S. entry into World War II, but they still speak to subsequent generations as alternative voices from a usable American past.

Professor Doenecke's new book, Storm on the Horizon, is by far the most inclusive work on pre-war isolationism ever written. Meticulously researched, easily read, and most informative, it is bound to become the standard study of this subject.

As Storm on the Horizon amply demonstrates, Justus Doenecke knows more about the so-called isolationists of the pre-World War II era than any other living historian. This comprehensive and even-handed book on opposition to American intervention should remain the standard account for generations.

Leo P. Ribuffo, author of The Old Christian Right

Eloquently argued and exhaustively documented, Storm on the Horizon traces the principles and practices of the non-interventionists from 1939 to the Pearl Harbor attack. While war ended their opposition, Justus Doenecke, as no scholar before him, demonstrates the logic and resolve of their lost crusade.

In this extraordinarily well-researched and comprehensive study, Professor Justus Doenecke examines the intellectual underpinnings of the American anti-interventionist movement of 1939–1941. Although much has been written about the bitter isolationist/interventionist controversy before America's entry into World War II, no one has ever systematically analyzed the anti-interventionists' mindset, motivating ideology, and prejudices. . . . Justus Doenecke fills this gap.
