Hitler did in fact serve in the army during the World War I, it is understood that he lost many men during the war even though his battalion fought well , and he was even awarded the iron cross. This evidence alone suggests that he must have a small perception of what propaganda would work, for he once must have been influenced by some sort of propaganda in order to join the war. Although the simple fact that he was a soldier is insufficient evidence to suggest he knows correct information about propaganda, but once again, by reading the book it is clear that he knows what he's saying, and for the most part, it is true.
Does Hitler Know What He's Talking About?
It's obviously debatable as to whether or not the opinions given in Mein Kampf in general should be considered or not, as most people would agree that Hitler is not a great example to take war ideologies from. However, ignoring his radical use of these ideas, his general thoughts of how propaganda should work does appear to be very reasonable. Simply by reading through Chapter 6, it becomes apparent that Adolf Hitler does know what he's talking about, and although he may use his knowledge to do some disagreeable events (holocaust etc), it would be unfair to say he didn't know what he was saying.
