 Remy states that the attachment to Hitler went much deeper than any gratefulness could explain, and that Hitler had become Rommel's source of motivation.Some, like Randall Hansen, highlight the similarities in background and personality that facilitated the rapport between the two, while others, like Richard Overy, state that Rommel's main appeal to Hitler was that he was everything Hitler was not, while the political scientist Roland Detsch, in a review of Maurice Remy's book, comments that despite Remy's efforts, the strange relationship remains hard to understand.Wolfram Pyta remarks that Hitler did not compete with Rommel for the war leader image because the two complemented each other perfectly.
