Friend Mark Safranski's take. He surmises deeper and more nefarious things going on. I'm not convinced, yet, but I respect him greatly.
2. Former aides wonder: Did Petraeus stumble in unfamiliar terrain?
John Nagl shared this on Facebook, saying 'Greg Jaffe with the best analysis yet of how this likely happened.'
3. As Details Emerge on Petraeus Affair, Fallout May Echo Far Beyond Resignation
John himself spoke on PBS tonight (shared on Facebook). Here's the transcript of his part:
GWEN IFILL: John Nagl, you have known General Petraeus for some time. Have you been in communication with him since this all broke?
LT. COL. JOHN NAGL (RET.), President, Center for a New American Security: I have.
GWEN IFILL: And?
LT. COL. JOHN NAGL: He is devastated, deeply contrite, very, very sorry about the harm he has caused to Holly in particular, his wife of 38 years, who has been really stalwart through his many deployments.
And he really feels that he's let the team down.
GWEN IFILL: How much of a surprise was this for you, having worked with him?
LT. COL. JOHN NAGL: It was absolutely a kick in the gut. I was astounded. I was shocked. I was very hurt and very surprised.
He has been a role model to me for literally decades, for nearly 25 years, a man I have admired and looked up to, a man I still think very highly of in many ways, but who clearly made a grievous, unforgivable error.
GWEN IFILL: Because there are so many people who have said that -- just what you just said, that they are great admirers of General Petraeus, what does this do to his reputation as a military man and also as a civilian leader?
LT. COL. JOHN NAGL: My hope is that, although it obviously and should damage his personal reputation -- his long reputation of personal integrity and good character, I think that reputation will never fully recover.
But I don't think it eliminates the fact or we should ignore as we look at the totality of the man the fact that two different presidents called on him in their hour of need.
And in both cases, he went to the sound of the guns and performed admirably under two very difficult conflicts.
GWEN IFILL: Do you have any reason -- have you had any reason to meet Paula Broadwell or know anything of her work?
LT. COL. JOHN NAGL: I do know Paula.
She's a very smart, very attractive, very driven woman, a fellow West Point graduate who has been very present in the Washington policy community and the national security debate.
And I am also sickened by the damage this will obviously do to her, to her husband, Scott, who I have met, to their children. And this is a very sad story for all concerned.
4. A General Lesson: David Petraeus was a decorated leader and strategic thinker. Why did he risk everything on an affair?
Shared by friend Patrick O'Connor. Interesting backgrounder on West Point.
