From the point of view of anti-Semitism, Hitler could look at Ford as somebody who was -- let's call him an age-mate. They were both in the 1920s beginning to write and disseminate information about what they both considered to be this great powerful threat, "the Jew."
And Hitler was very much inspired by Ford's writing. And the idea that this could happen in the United States, I think, was very important to Hitler as well, because as people in the United States were speaking out against Nazism and were using a kind of rhetoric, "Well, it could never happen here," and "We are the bastions of democracy," I think Hitler would have derived a degree of satisfaction to be able to point to Ford as, in a way, just as good an anti-Semite as he was.
