The Nazis Strike is the second film of Frank Capra's Why We Fight propaganda film series. It introduces Germany as a nation whose aggressive ambitions began in 1863 with Otto von Bismarck and the Nazis as its latest incarnation. Heartland Theory Hitler's plan for world domination is described in terms of Halford Mackinder's Heartland Theory, which starts about three minutes into the film: Fifth column activity The next focus of the film is the "softening-up" of the Western democracies by using fascist organizations such as the Belgian Rexists, the French Cross of Fire, the Sudeten German National Socialist Party of Konrad Henlein, the British Union of Fascists, and the German American Bund. Meanwhile, in Germany, the Nazis are beginning an enormous process of rearmament. Germany then begins its territorial expansion with the first target being Austria, Hitler's "full-scale invasion test." He then uses his Sudeten "stooges" under Henlein to "soften up" Czechoslovakia and to annex the Sudetenland with the help of a Britain and France, which are desperate to avoid war. Hitler's use of the concept of self-determination as a justification for these annexations is ridiculed by reference to prominent German Americans thoroughly loyal to the Allied cause, such as Admiral Chester Nimitz, Henry J. Kaiser, Wendell Willkie and Senator Robert Wagner. Invasion of Poland The film concludes with the Invasion of Poland, which is depicted with many inaccuracies. The extreme disparity between the two sides is emphasized. The Germans have 5,000 modern tanks against Poland's 600 obsolete models, and the Luftwaffe has 6,000 modern monoplanes against less than 1,000 aircraft of the Polish Air Force, many of which are outdated biplanes. Animation is also used that graphically shows how Polish army units were encircled and destroyed. The film suggests most of the Polish Air Force to be destroyed on the ground and the Polish Army to rely heavily on mounted cavalry (see Tuchola Forest myth) That suggests that its makers learned the details of the Polish campaign largely from Nazi propaganda in which both false claims were often made. The stubborn resistance of Polish forces in the Hel Peninsula is recognized, as are the widespread Nazi atrocities after the Polish defeat. Overall, the movie gives the false impression that Polish Army to be ineffective and even pathetic and to do no damage to the Germans. The film also alleged widespread collaboration with the invading Germans but does not specify
