You keep mentioning Israel, and I may regret this, but I have to ask. Just to summarize, you think Broadwell or Kelly, or both, are Israeli spies that were used to come and topple the highest seat within the CIA? What spy ring do you think might be out there?
I think you may be overthinking it. I think in the beginning, the knowledge of the affair was brought to the Obama Administration's attention. Regardless of Obama's direct knowledge, Petraeus is told that it would come out, and he is strongarmed to jump on the bandwagon touting "the video" story to keep it under wraps. This FORCED Petraeus to go AGAINST the word of the boots on the ground in Libya from the CIA itself. Why else would Petraeus go against his own men on the ground?
Then, whether it be integrity, honor, or whatever, now that the issue has not gone away, and the hearing tomorrow morning is under oath, Petraeus fessed up to the affair, let it come out, and now he has no tie or evidence being held over his head. So the question is, what will he say behind "closed doors" tomorrow? Unfortunately, we won't know... the public will still be left in the dark.
I hope Senators Graham and McCain come out with it though

All great theories, though.
