I remember an interview with the late author Vince Flynn. He was asked about Petreaus because a character in his last thriller seemed to be based a bit on Petraeus (high-ranking military intelligence officer in Iraq having clandestine affair). Flynn said he had met Petraeus and got a bad vibe from him. He struck Flynn as a "political general" who had an overly developed sense of self-importance.
I just looked and here is that interview with the late, great Vince Flynn: Video of Interview
That’s interesting, thank you.
