Until this week, a Major in the U.S. Marine Corps; known to a wide public through the articles syndicated by the Scripps-Howard papers, Major Williams is qualified to speak with authority in his chosen field, airpower. For years he has systematically investigated the European aviation centers, and the text shows his intimate knowledge of modern aircraft, engines, models, construction, organization et al. On that subject, we are not equipped to cavil. But, when his text is interlarded with such remarks as ""Anti-Nazi feeling is one thing, and it may be all right"" -- ""England decided this was the time to break Germany"" --""Hitler would never touch a hair of an American head"" -- ""England is our only enemy"" etc., etc., I confess that any pretense of purely objective appraisal of his book goes out the window. It is hard to pin the impression down to specific phrases, but the whole book is permeated with criticism of every nation except Germany and Italy, and the final impression is that he is rooting for the Fascist powers as the bulwark against Communism, and that he sees a Red Peril under every bush. Perhaps it is a point of view that should be expressed openly; perhaps it is the very type of book intended by those of us who feel that Public Libraries should be custodians of all sides of a question before the world. But, in the last analysis, though his criticisms are undoubtedly well-founded, and his charges have, in the past, been proved true again and again, it is hard to avoid pointing the finger of ""Pro-Naziism"" towards anyone whose bias seems so patently that.
