This survey of the development of the main problems of American foreign relations from the end of the war to the spring of 1947 is the first of a new series of annual volumes, similar to those published under the auspices of the Council on Foreign Relations from 1931 to 1940. The author has devoted himself to narration rather than interpretation; covering two years in one volume, he has included a surprising amount of information in a framework of reasoned analysis. For reference purposes the bibliography and chronology of events should prove most useful.
