I may be going out on a limb here but this sounds, in many ways, like the current Anglo-American attitude towards Islam in general and Arabs in particular. It can't be quite the same because there are some reasons why the Anglo-American viewpoint is understandable but still..
Like most extreme attitudes in humans it seems to me that the attitutde towards Germans desctibed by Ollie is borne out of fear, but for different reasons than we are taught at school.
