Just because we have the best hammer does not mean that every problem is a nail.

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.

This is American leadership at its best: We stand with people who fight for their own freedom, and we rally other nations on behalf of our common security and common humanity.

That may prevent us from getting a deal done, It is there to be had. Whether ultimately Iran can seize that opportunity - we will have to wait and see, but it is not for lack of trying on our part.

We also think this is a reminder of the long tradition of bipartisan foreign policy that has been the hallmark of America at moments of greatest need, and that's the kind of spirit that we hope will be reflected in our administration.

Each path to knowledge involves different rules and these rules are not interchangeable.

Tonight, I can report to the American people and to the world that the United States has conducted an operation that killed Osama bin Laden, the leader of al Qaeda, and a terrorist who's responsible for the murder of thousands of innocent men, women, and children.
