Strategy, Security, and Spies tells the fascinating story of U.S. relations with Mexico during the war years, involving everything from spies and internal bureaucratic struggles in both countries to all sorts of diplomatic maneuverings. Although its focus is on the interactions of the two countries, relative to the threat posed by the Axis powers, a valuable feature of the study is to show how Mexico itself evolved politically in crucial ways during this period, always trying to maintain the delicate balance between the divisive force of Mexican nationalism and the countervailing force of economic dependency and security self-interest.
