The single biggest existential threat that's out there, I think, is cyber.

I think the central mission in Afghanistan right now is to protect the people, certainly, and that would be inclusive of everybody, and that in a, in an insurgency and a counterinsurgency, that's really the center of gravity.

It has been a little surprising to me, anyway, is to find out through media that there actually have been several chemical attacks recently. Now, with some belief on my part, and I think a lot of people, that we thought we got rid of the chemical weapons with the regime that President Obama and President Putin put in place.

The mission - the overall mission is to dismantle and defeat and disrupt al-Qaeda. But we have to make sure there's not a safe haven that returns in Afghanistan.

I worry a little bit about - quote - "regime change." We haven't had a great deal of success with that in years. That's just really difficult.

The best day was when we got bin Laden.

We're at a real time of transition here in terms of future aviation. What's going to be manned? What's going to be unmanned? There are those who see [the JSF] as the last manned fighter/bomber. And I'm one that's inclined to believe it-whether it's right or not.
