~Virginia Quarterly Review
This is an analytic study of American intelligence gathering about technological developments in Britain, Germany, and Japan, as well as what was—or wasn't—learned and the uses to which the information was put. In the process, the book discusses the American military attaché system, which, it appears, was the most extensive of any of the great powers, evaluates the overall effectiveness of the effort, and throws some light on a few surprising corners, such the obstacles created by the Neutrality Acts in terms of intelligence co-operation with Britain.
