In this useful volume, leading strategic analysts from the United States and Japan examine the rationale of the security relationship between the two countries in light of post-Cold War realities and the overall East Asian geopolitical environment. They argue that the alliance has served, and can continue to serve, the national interests of both countries and that the risks and costs of going it alone would be dangerous and destabilizing. There are a number of useful suggestions, and there is a particularly cogent essay by the editor, which seeks to expose a number of the prevalent myths about the alliance. For example, there is the false idea that Japan gets a free ride on defense. In fact, even with U.S. security guarantees, Japan's defense budget is the second-largest in the world (after the United States').
