Like many in the press, nearly every national politician, and lots of members of Petraeus’ brain trust over the years, I played a role in the creation of the legend around David Petraeus. Yes, Paula Broadwell wrote the ultimate Petraeus hagiography, the now-unfortunately titled All In. But she was hardly alone. (Except maybe for the sleeping-with-Petraeus part.) The biggest irony surrounding Petraeus’ unexpected downfall is that he became a casualty of the very publicity machine he cultivated to portray him as superhuman. I have some insight into how that machine worked.
