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.

The best day was when we got bin Laden.

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 you listen closely to the voices of our veterans, you understand that yes, they all returned from war changed, but what never changed is this: They never forgot your generosity. They never forgot the power of opportunity. They never forgot the American dream.

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.

The truth is, we live in deeds, not days; in actions and thoughts and feelings, not heartbeats.

We have to stop the killing. We need to let the refugees - we need to let Syrian citizens go home.
