In an interview with the French newspaper "Le Monde" on 10/20/09, published on 10/21/09, Michael Haneke has explicitly and unequivocally declared his intentions in making the movie "The White Ribbon":
He intended to make a movie about the roots of evil. He said that he believed that the environment of extreme, punitive and sexually repressive protestantism in Germany, has laid the groundwork for Fascism and Nazism. He also said that he saw the same patterns developing in fundamentalist Muslim societies today, and that it is those societies that today were spawning terrorists and suicide bombers. Finally, he expressed the sentiment that "The White Ribbon" is a movie against ALL extremisms.
Michael Haneke has directed his vision in a very masterful and artful way: the cinematography, the acting, and the script are all superb.
The only problem I have is with the vision itself: The environment certainly plays a role, but to explain evil exclusively as the product of one's environment is simplistic and goes against common sense observation: The majority of people on this earth have grown up under repressive regimes and yet have NOT turned out to become murderers, mass murderers, terrorists or suicide bombers. Something is missing in the equation.
