Immigration keeps this country young, it keeps it dynamic, we have entrepreneurs and strivers who come here and are willing to take risks, and that's part of the reason why America historically has been successful.

Our country was born out of a desire to be free. And every day since, it's been protected by our men and women in uniform - people who believed so deeply in America, they were willing to give their lives for it.

The future rewards those who press on. I don't have time to feel sorry for myself. I don't have time to complain. I'm going to press on.

Some heinous crimes justify the ultimate punishment.

When any kind of military action is popular it's because either there's been a very clear, direct threat to us - 9/11 - or an administration uses various hooks to suggest that American interests were directly threatened - like in Panama or Grenada. And sometimes, those hooks are more persuasive than others, but typically, they're not put before Congress.

That sort of lack of awareness on the part of an activist about the constraints of our political system and the constraints on this office, I think, sometimes would leave me to mutter under my breath. Very rarely did I lose it publicly. Yeah, usually I'd just smile.

So Americans understand the costs of war. Yet as a country, we will never tolerate our security being threatened, nor stand idly by when our people have been killed. We will be relentless in defense of our citizens and our friends and allies. We will be true to the values that make us who we are.
