This great five-volume series, by Guido Knopp, examines the naivete of German youths in the 1930's and 1940's. This is the only documentary I have seen that focuses on the way the Nazis used children to conduct their war.

In this first volume of the series, we see the exploitation by the Nazis of teenagers' natural tendencies toward self-importance and rebellion. Using this as a foundation, Hitler built a large community of child soldiers and moulded them into hateful killers through peer pressure and fear of humiliation. (less info)
