First published in 1909. According to Wikipedia: "Friedrich Adolf Julius von Bernhardi (November 22, 1849 – December 11, 1930) was a Prussian general and military historian. He was one of the best-selling authors prior to World War I. A militarist, he is perhaps best known for his bellicose book Deutschland und der Nächste Krieg (Germany and the Next War), printed in 1911. He advocated a policy of ruthless aggression and complete disregard of treaties and regarded war as a "divine business".
