That clip only tell half of information about crazy dude. From other sources that I do know that sort of connect the dots: One, he's from Catholic family. Two, he's a deluded moron who's afraid to be left alone. No wonder he need a large group of Germans feed his ego. Three, other country like Austria did not want to be part of his Third Reich (Unification of Germany).

Bonus
Watch the movie, The Sound of Music. This movie was based on true story. Austrians were forced to join in the Nazis and some others fled to America as immigrants.
