First: congratulations to you for this great publication. I think you were objective, keen and sincere.
Maybe I do not agree with your opinion because I have lived in my own flesh the famous "psychological warfare" or last generation marketing. I am Venezuelan and I live in Venezuela. Here they tell you through the media that "you are fine, it doesn't matter if you haven't eaten"; "You are well hungry, working every day without the money reaching you because you agree with the political system."
From your observations, I read that the book does not justify Nazi propaganda. But that "removing the horror" was a very smart strategy. I do not know what to say...
For me nothing is justified if the goal is submission by whim. Nothing is justified if the goal is even the death of the "other" to achieve the ultimate goal. BUT I RECOGNIZE that this way of thinking is part of the history of mankind.
Great review of the book . A cordial greeting
