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.

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.

I am convinced that America's great sea of goodwill can be, in fact, a rising tide, a tide that could lift every veteran and every family of our wounded and fallen.

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.

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.

I think anybody in our - in the, in the national security apparatus has, has got to take full cognizance of their responsibility for the safeguarding of classified information.

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.

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.

I'd have no problem serving under any president.

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 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.

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.

We can't kill our way to victory, and no armed force anywhere - no matter how good - can deliver these keys alone. It requires teamwork and cooperation.

Our people sacrifice a lot for their country, including their lives. None of them should have to sacrifice their integrity as well.
