2. This is not about Benghazi. Petraeus’ resignation will not prevent him from testifying to Congress about Benghazi, even though he wants to avoid testifying in order to avoid embarrassment. Every report that links his resignation to Benghazi is predicated on the assumption that the president of the United States decided to blackmail the CIA director. There is nothing anywhere to support that assertion.
3. Petraeus’ behavior was logical. Like many, but not most, men, he cheated on his wife. He tried to hide it. He did not voluntarily disclose his transgression to superiors or colleagues. He became embarrassed when the affair was exposed and resigned. He tried to hold on to his job because there is no reason to believe that his performance as CIA director would be hurt by the affair itself; instead, he knew that its revelation would do the damage. His choice of Paula Broadwell was logical. She was around him, known to him and trusted him, and had a security clearance. If Petraeus were to have an affair with anyone, and if his having an affair was an order from a deity, you’d kind of want him to have it with someone who knows him.
