This is a history book. This is one of the best books that has appeared about the war. It shows conclusively why the United States must put this war through to a finish, and why every good American and every believer in liberty and civilization must be heart and soul against Germany. The fact that Mr. Kahn himself is of German origin emphasizes the contention which every good American should make, namely, that the Americans who are in whole or in part of German blood should eagerly take the front places in this war for Americanism against the attempt of the Prussianized Germany of the Hohenzollerns to establish a world tyranny.
