This book makes a contribution along lines that have been overlooked:-- the differences (instead of the resemblances) between 1914 and 1939. They show how changed our state of preparedness is, not from the angle of army and navy so much as from the angles of war finance and war economy, from the diplomatic front,' from the channels of communication, from the curbs on war booms in industry, in the stock market, in agriculture. They outline the set-up in Washington for research, for organization, which seem to indicate that there is a machinery of keeping our own preparedness in order and at the same time supplying those nations that can conform to the regulations. They warn against scareheads here, as a graver, peril than anything the press or radio can do, under the restrictions now prevailing. Succinctly done, with touches of humor.
