Why We Fight (Part 1)
This is a movie about the Nazis. The Nazi-German aggressive impulse is dated by the Americansto the time of Bismarck. This should not surprise. It was important to build up support for a war against Nazi Germany, and that could not be done by simply carefully distinguishing the "bad extremist Nazis" from the country, Germany, most of whose people had come to enthusiastically endorse Hitler and the Nazis, and all of whom were part of the Nazi war effort and would have to be defeated, through force, if the Nazis were not to win. The director of this film, and others not only in this series of four but of other series about the reasons for, and conduct of, the war, was the great Frank Capra. Most Americans think of Frank Capra round about Thanksgiving, when they see the America of their dreams in "It's A Wonderful Life."
Halford Mackinder's "Heartland" theory comes in around 6:40. The German geostrategist Hausdorfer is mentioned earlier.
See especially the last two minutes of the film, begining at about 8:10, about those who in the Western world aided the Nazi propaganda effort to confuse and mislead and trap the unwary.
Note the quote from Hitler at 8:12:
"Demoralize the enemy from within by surprise, terror, sabotage, assassination. That is the war of the future."
Then look at the next two minutes about the local agents used to "soften up" his intended victims.
The American film is about the threat posed by the Nazis. The present, much wider threat, to the civilised world and its people, can be dated back to 1200 years before Bismarck.
