Mr. Knickerbocker is a widely known and widely read journalist. This book is not, however, the usual travelogue of a returning foreign correspondent. Instead, the author has chosen some 200 of the more insistently significant questions put to him during an extensive lecture tour and has tried to give concrete and realistic answers. The result is not as disjointed as one might expect, for the questions are arranged in a roughly logical sequence under the general headings of Germany, Russia, England, War Aims, France, the United States, and Fifth Columnists. In the latter category he places Lindbergh and other "isolationist" leaders, on whom he is very severe.
