An examination of the current problems of Latin-American and United States relationships, from a general basis, this emphasizes the need to act, and continue to act, intelligently-with an understanding of the low productivity and its results, ignorance, disease, hunger, and political instability. From an historical perspective -- of the Spanish heritage, in social, economic, military survivals -- to a consideration of U.S. intervention and recent conferences and the current reforms in agriculture, industry and labor, this predicates a peaceful revolution only if the old and new orders co-operate, presages not only internal but hemisphere troubles if this does not come to pass. It calls for not only U.S. sympathy but for financial and technological aid; it demands that the opportunity for brotherhood be not lost; it aligns misgivings along with hopes. Again a book for those versed in the terminology of international dealings, in the importance of tabulations and figures, -- the student rather than the man in the street. An argumentative book for experts in the field.
