Microscopically examining the whole kaleidoscope of American foreign relations from the ancient days of Spanish imperial exploration to the present days of Russian communist expansion, Dr. Bartlett has achieved a tome. With its straightforward, dusty-dry style, it makes no pretense at being easy reading. It is jammed with dates and data. Since the author is Professor of Diplomatic History at the Fletcher School of Law and Diplomacy at Tufts University, he will have a ready student market. In Policy and Power Dr. Bartlett does not attempt to provide the color of history but to tackle its complexities and make sense of its intricacies. He thinks in terms of governments and not of men and does not appear to be impressed by the influence of personality on policy making. The book is written with an authority which should appeal to all specialists of diplomatic history who wish to study form. Making sense out of recent decades of American foreign policy, without passing judgment on those policies, is one of the achievements of the book. The last few chapters are the most interesting for lay readers who have kept up with their New York Times.
