Here Is Germany is a 1945 American propaganda documentary film directed by Frank Capra and written by William L. Shirer, Gottfried Reinhardt, Ernst Lubitsch, Georg Ziomer and Anthony Veiller.
Going even further back to identify the cause of this 150 years, the film informs us that while America, Britain, and France were forming their democratic traditions, Germany was a group of 300 medieval feudal states, not one of them with a constitution or parliament.
When the nationalist militarists knew that they were beaten, according to the film, they allowed democratic parties to take the reins of power and immediately set about destabilising and discrediting the new republic.
The film depicts the Third Reich from this perspective, seeing Nazism as simply a continuation of the aggressive German tradition, promoted by the military–industrial complex (those businesses dependent on government contracts for arms).
The film finishes with a list of different things that are being done to prevent Germany from starting another World War, chief among them the total conquest and control of the German state.
