Whenever I was misbehaving as a young man, my late great Dad always threatened to send me away to military school. I had no idea that my father -- a Naval officer back in the day -- was thinking of ways for me to someday meet women.
Just because there are no e-mails that are flatly incriminating, does this means that secrets weren't passed? What do men do to impress the women with whom they're involved? They show off. Can we be absolutely sure that Petraeus didn't say things to impress his paramour?
An American hero like David Petraeus who served his country with distinction and honor deserved better than to leave his post in humiliation and ignominy, even if his own immoral actions brought it upon himself.
