Nazi Hitler's Propaganda And "Nazi Mega structures"

 I watched Historical Nazi Hitler's Propaganda on Net-Geo People.

Today I watched World war 2 Nazi Hitler's Propaganda in " Nazi Megastructures" .how he use to brainwash the whole German nationals. it is really a big deal to manipulate millions of peoples.and how create megastructures before the world war begin.

                    I was wondering how he manages to do that. and how he is the creator of the world war.

                    I really won't know about him some more. 
DO You have any other video link to know more about Nazi Hitler? Please do share the link. i would like to watch
