What is certainly true is that the United States has to have a presence to promote the values that we care about.

America is much less violent than it was 20, 30 years ago, and immigration is much less a problem than it was not just 20, 30 years ago, but when I came in as president.

One of the things that we have to change in this country is the idea that people can't disagree without challenging each other's character and patriotism. I have never suggested that Sen. McCain picks his positions on national security based on politics or personal ambition. I have not suggested it because I believe that he genuinely wants to serve America's national interest. Now, it's time for him to acknowledge that I want to do the same. Let me be clear: I will let no one question my love of this country.

Let it be said to our children's children that when we were tested we refused to let this journey end, that we didn't turn our back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.

I think that what is always true when you run against an incumbent president is, is that you end up talking more about that president's record than your vision for the future, and I think that the Democrats do have to present a proactive agenda and vision for the country and not simply run against something if they're going to be successful.

I think if you look at almost every year under every president over the last, I don't know, 20, 30 years, you're going to be hard-pressed to find a year in which the majority of Americans thought we were on the right track.

To those of you mourn the loss of a loved one today, my heart goes out to you. We remember that the blessings that we enjoy as Americans came at a dear cost. Our nation owes a debt to its fallen heroes that we cannot ever fully repay. But we can honor their sacrifice, and we must. We must honor it in our own lives by holding their memories close to our hearts, and heeding the example they set.
