"Dunn rightly calls this [sense of purpose] ‘a decisive, irreversible shift in national consciousness,’ transforming America from isolationist into internationalist. . . . Much of this had only been half explained, and Dunn’s achievement is to make the view of FDR’s accomplishment clear."—David M. Shribman, Boston Globe“A Blueprint for War is a thoroughly researched book by a prominent scholar” —Manfred Berg, The Journal of American History“Susan Dunn is one of the great Roosevelt historians of our time, and with this fresh and fascinating book, she has proven it once again.”—Michael Beschloss, author of Presidents of War“A superbly researched and written history of how FDR and his top aides moved decisively after the 1940 election to provide massive American aid to Great Britain to support its lonely fight against Hitler, and how FDR set forth an enlightened and lasting vision of America's international responsibilities in the future.”—James T. Patterson, Bancroft Prize-winning author of Grand Expectations“A Blueprint for War should become the definitive telling of a pivotal episode in American history.”—Edward J. Larson, Pulitzer Prize-winning author of The Return of George Washington“Susan Dunn has written a wonderful book about an important and, until now, under-examined chapter of Franklin Delano Roosevelt’s presidency. In A Blueprint for War, we see Roosevelt at his best—the skilled navigator of domestic politics and the visionary shepherd of U.S. foreign policy. Dunn shows how FDR’s Third Hundred Days were critical to overcoming isolationism and rebuilding American leadership in age of global turmoil.”—E.J. Dionne Jr., co-author of One Nation After Trump
