The Korean War has- for some- been considered the ""acid test"" of the U N. In this book, Mrs. Roosevelt, who has been an American representative for seven years, and a trained journalist, have collaborated to present the story of a world organization that is a functioning body with vast accomplishment to its credit. There has been no effort to minimize the failures- the deadlocks- the difficulties encountered, and the reasons for them. But the authors feel that concern with therights of all people to human freedom, economic advance and eventual self government is the chief trend. Since the beginning of U N, some 800 million people have been freed from alien rule. While the reduction of political effectiveness and the weakening of the power to maintain peace are recognized (for the time being, they hope)- the U N has turned more to economic, social, cultural directions. The minute description of the three main units of buildings, their organization and the machinery behind the scenes will interest many. But the kernel of the nut lies in the study of the specialized agencies and their achievements:- health, food, children, education, labor, money, mail, communication, weather, civil aviation -- in all these fields the U N can point with pride to great progress. The parts played by external organizations is also discussed. Closing sections include a question and answer chapter, and the text of the U N charter. A valuable handbook, which challenges our ignorance of an already vital force in the world. One could wish for more anecdotal material, more human bits on leading figures, but even so the book has great value.
