Partly this was because he published half a dozen books in German, compiled from the long newspaper articles he wrote, which appeared serially in the _Vossische Zeitung_ or the _Berliner Tageblatt_. The books were extraordinarily successful in Germany; they introduced German readers to a new type of American journalism. Among them were _Der Rote Handel Droht!_, _Der Rote Handel Lockt!_, _Kommt Europe Wieder Hoch?_, _Rote Wirtschaft und Weisse Wohlstand!_, _England’s Wirtschaft und Schwarzhemden!_, _Deutschland So oder So!_, and _Kommt Krieg in Europa?_ Knick knew practically every human being of consequence in Germany. He explored the country from top to bottom. He talked to Hitler, Spengler, Brüning, Goering, Goebbels. Then Hitler came to power. At the time Knickerbocker was in the middle of a German lecture tour that had begun in the Lessing Hochschule in Berlin. Knick watched the Nazi revolution crushingly obliterate all opposition. He wrote a series exposing the Brown Terror that caused violent comment in New York as well as Berlin. Presently he was excluded from the country. There are hate affairs as well as love affairs. The hate affair between Hitler and Knickerbocker is one of the most torrid in political history. But this should not detract from the main point, which is that Knick knows the real Germany, loves it, and respects it. He is a Nazi-hater, but not a German-hater. His authority on the subject is authentic and complete. _John Gunther_ INTRODUCTION There is no such thing as winning a fight without passion. France went to war apologetically; France fought the war without music, and so France lost. Britain went to war apologetically, but Britain had the inestimable advantage of being bombed, and today for the first time in 100 years Britain is angry and is fighting as she has never fought before. We, the United States, are today apologetic, so sorry that it seems we after all are called upon to fight, and some of us still say we should not fight, and others say we must fight only with aviators and sailors, and never with infantrymen, and very few indeed are the strains of martial music throughout the land. From all sides we are called upon to restrain our emotions, and it is said that the cool head is the shrewd head, and that is correct, of course, but a cool head without a hot heart is useless on a battlefield. Without anger there can be no victory and useful anger is based upon understanding. Unless the American people can be brought to understand that our national existence and our individual security are today in peril, and unless the American people become angry at the enemy, we shall become a part of Hitler’s Reich.
