Germany Must Perish! is a 104-page book written by Theodore Newman Kaufman, which he self-published in 1941 in the United States. The book advocated the genocide through sterilization of all Germans and the territorial dismemberment of Germany, believing that this would achieve world peace. Kaufman founded the Argyle Press in Newark, New Jersey, United States, in order to publish this book. He was the sole proprietor of the Argyle Press and it is not known to have published any other works.
The Nazi Party used the book, written by a Jewish author, to support their argument that Jews were plotting against their country.
Though written and self-published by a non-notable author, the book received considerable attention. Time magazine published a review in its 24 March issue that compared the book to Jonathan Swift's 1792 satirical essay A Modest Proposal, which proposed reducing the population pressure in Ireland by the cannibalistic consumption of poor Irish children. However, the Time essay recognized that Kaufman's work was not satirical; it described the book as the "enshrinement of a single sensational idea". "Since Germans are the perennial disturbers of the world's peace, says the book, they must be dealt with like any homicidal criminals. But it is unnecessary to put the whole German nation to the sword. It is more humane to sterilize them."
According to one study, reviews in the United States "reflected an odd combination of straight reporting and skepticism". Kaufman's second and more moderate pamphlet, "No More German Wars" published in 1942, was ignored both in the U.S. and in Germany.
An advertisement in The New York Times stated that the book was released to the public on March 1, 1941. Kaufman also promoted the book by mailing a miniature black cardboard coffin with a hinged lid to reviewers. Inside the coffin was a card proclaiming, "Read GERMANY MUST PERISH! Tomorrow you will receive your copy."
The book's dust jacket contained excerpts from reviews of the book. One blurb read: "A Plan For Permanent Peace Among Civilized Nations! -- New York Times."
