Although mainly concerned with the Japanese economy, this book also has some useful insights into Japan's relations with the world. Kahn, always provocative, has had some second thoughts about the probable future of Japan. In an earlier work, he made a number of comparisons between contemporary Japan and 19th-century Prussia. Now he sees reasons why Japan's low-posture policy may work more or less indefinitely, particularly if the U.S. is strong and reliable enough as a partner. He is especially convincing on the need to maintain U.S. force levels in the Pacific and on the many useful and admirable aspects of the so-called Japanese free ride.
