If you want to create a movement that will encapsulate a nation over time, the majority of your propaganda resources are best allocated toward changing the hearts and minds of the children, not the adults. This tactic is a viciously well-known and time-tested strategy of dictatorships worldwide. During the rise and reign of Adolf Hitler, no other target of Nazi propaganda took higher priority than Germany's youth. As early as 1937, 97 percent of all teachers belonged to the National Socialist Teachers' Union and the “created facts” within the textbooks in Nazi schools were a reflection of the mindset that Nazi Germany wished its children to carry into the future.
