"He had in him the stuff of which legends are made.” Is Dietrich somehow referring to himself as being the "legend" and "son of Adolf Hitler"?
Of course, this is all untrue from Dietrich's POV since his mother was not a "diplomatic level interpreter" in 1936 - because she was only 13 years old. And the "stuff" she supposedly stole from Hitler could not have been preserved for 30 years before she inseminated herself with it.
Another deception Dietrich is using is in his citation "PRELUDE TO LEADERSHIP (see pp [pages] 73—74),” The “Postwar” Diary ‘o’ THE LATE JOHN-FITƵGERALD KENNEDY "
