Petraeus...

[Danzig]

i try not to get worked up about hypotheticals.

is he a fool? yes. but unless/until something actually worrisome comes out, it's a non-story to me. sorry.
and 'easily trapped'? i doubt he thought he was being trapped. and unless she had something nefarious in mind, then i have to think it was just an affair.
and she doesn't sound particularly smart, knowing about the ridiculous emails she sent. if she had a cunning plan, she botched it pretty badly.
i seriously doubt either one of them thought all their actions thru. if they had, the affair wouldn't have happened.

and, after months of inquiry, there was no ticking time bomb. just not seeing a grand conspiracy to worry about.
