The career of Joseph C. Grew began before there was a Foreign Service and ended, appropriately, as the sun rose on the early days of the Cold War. A man of protocol first and last, as Professor Heinrichs makes clear, he was adept at carrying out the strategies of planners at the top, if not an initiator of major policy himself. His early tours of duty in Berlin at the outbreak of World War I and his idyll as our minister to Turkey, his stint in the State Department where he helped to carry our reforms of the Foreign Service, seem hardly significant in the face of his later mission as Ambassador to Imperial Japan. There he walked the fine line between peace and war and the test of his career became the test of our nation--only after the excruciating dalliance of diplomacy did we finally commit ourselves to war. Here in handling Grew's role in the formation of postwar policy, does Heinrichs' treatment seem to lack a certain perspective: for in this period Grew's rabid anti-Communism seems to have placed him in an unlikely policy-making position... Generally the book will appeal to those in the Foreign Service and historians, lay and professional, at large.
