Query: Hitler, An Understanding Of A Mechanical Mind

No doubt this will offer the reader retrospective insight deep into the mechanical mind of Hitler. Easily set aside from Mein Kampf and ramblings, this volume should be standard reading in all military science curriculum.What is most concerning is not Hitler's perversions. Rather, it was his ability to consume and control a nation of people; possibly the greatest salesman of the 20th century.
