There remains now but to determine the best way, the most practical and expeditious manner in which the ultimate penalty must be levied upon the German nation. Quite naturally, massacre and wholesale execution must be ruled out. In addition to being impractical when applied to a population of some seventy million, such methods are inconsistent with the moral obligations and ethical practices of civilization. There remains then but one mode of ridding the world forces of Germanism—and that is to stem the source from which issue those war-lusted souls, by preventing the people of Germany from ever again reproducing their kind. This modern method, known to science as Eugenic Sterilization, is at once practical, humane and thorough. Sterilization has become a byword of science, as the best means of ridding the human race of its misfits: the degenerate, the insane, the hereditary criminal.
