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.

If the untimely battlefield deaths of generations of American heroes have taught us nothing else, it should be this unalterable fact: what you do with your time here on earth is far more important than the time you had to do it. Those who live most are those who love most, who act the noblest and do their best.

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.

We think we're near energy independence - nothing could be further from the truth. We're in much better shape now, but the price of a barrel of oil is going to be controlled by the Middle East for the next 10, 20, 30 years for sure.

Few things are more damaging to our democracy than a military officer who doesn't have the moral courage to stand up for what's right or the moral fiber to step aside when circumstances dictate.

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.

To the Cold War veterans here, know that your steadfast efforts preserved a delicate balance, and, because of you, the global war that many feared never came to pass. We are thankful for you, as we are for all the veterans here with us.

I'd have no problem serving under any president.

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.
