Panetta isn't Gates. He's a career Democrat and a Clinton guy. He's a conformist. He goes along. And yet he's still making the admission.
As secretary of defense, he tells me, one of his most important jobs was keeping Prime Minister Benjamin Netanyahu of Israel and his defense minister, Ehud Barak, from launching a pre-emptive attack on Iran's nuclear facilities. "They were both interested in the answer to the question, 'Is the president serious?'" Panetta recalls. "And you know my view, talking with the president, was: If brought to the point where we had evidence that they're developing an atomic weapon, I think the president is serious that he is not going to allow that to happen."
Panetta stops.
"But would you make that same assessment now?" I ask him.
"Would I make that same assessment now?" he asks. "Probably not."
Not news to anyone with any common sense. But probably a big admission within the echo chamber.
