Even though the intro says that the movie is not about two races but about two people it's clear that the two people were never intended to have a happy existence. It would appear at times that the two would find some sort of Happiness together but the underlying theme was tragedy. The fact that the movie was banned in the United States and in Germany speaks volumes about racial attitudes at that time with some claim in this country don't exist. The fact that American soldiers were segregated goes against what many claim wasn't unsegregated military. My own dad served in the Army and was in Italy and in North Africa and told me that he was treated better there than he was in the United States of America.
