A collection of essays on the key issues of nuclear arms control, with several of them dealing with other matters such as energy security and international terrorism. Many of the authors are eminent defense policy experts, and there is a balance in the political perspectives, but the contributions are too brief to bring much that is new to the ongoing debate. They do serve, however, to underscore how deep the fissures are on such issues in the American body politic and how difficult-and important-it is to grapple with them.
