In the past few years a large number of books, articles, and pamphlets have been published on the future problems of underdeveloped countries. In most of these accounts, economic, cultural, or administrative questions receive chief attention. Mr. Staley has now produced a book in which the international political problems of the underdeveloped countries are given primary emphasis. In particular, the book concentrates on one problem area: what role do underdeveloped countries play in the present division of the world into a Communist and a non-Communist bloc; what are the doctrines and strategies the Communists have worked out for underdeveloped countries; what chances are there of the underdeveloped countries falling under Communist domination; and, finally, what policies can be adopted by the non-Communist countries, particularly the United States, in order to keep free from Communist infiltration and subversion as large a portion of the world as possible?
