The author, who has been writing articles on arms sales for a decade, has culled his facts and insights into this volume. The emphasis is on U.S. policy over the past four administrations, rather than on the global dimensions. There is little that is new here and some of Klare's past criticisms appear a bit tempered, even though he retains his skeptical attitude toward arms transfers as an instrument of policy. This is a well-organized and impressive work on a complex phenomenon.
