"Magisterial . . . This book is without question a major achievement. It is a masterly work of synthesis, weaving together in a single coherent study the various and often contradictory trends in previous historical writing on the Cold War's origins. It is indefatigably researched . . . and most important, it is an intellectually honest work. . . . A fine book."The Atlantic "A brilliant new book. . . .
