My goal is to maintain the international norm on banning chemical weapons. I want that enforcement to be real. I want it to be serious. I want people to understand that gassing innocent people, delivering chemical weapons against children is not something we do. It's prohibited in active wars between countries. We certainly don't do it against kids. And we've got to stand up for that principle.

When I touched my hand against the Western Wall and placed my prayer between its ancient stones, I thought of all the centuries that the children of Israel had longed to return to their ancient homeland. When I went to Sderot and saw the daily struggle to survive in the eyes of an eight-year-old boy who lost his leg to a Hamas rocket, and when I walked among the Hall of Names at Yad Vashem, I was reminded of the existential fear of Israelis when a modern dictator seeks nuclear weapons and threatens to wipe Israel off the face of the map - face of the Earth.

In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope?

Part of what makes me most optimistic is if you look at the attitudes of young people. Across the board, young people are much more comfortable with respecting differences. They are much more comfortable with diversity.

The day I'm inaugurated, this country looks at itself differently and the world looks at America differently. If you believe that we've got to heal America and we've got to repair our standing in the world, then I think my supporters believe that I am a messenger who can deliver that message around the world in a way that no other candidate can do.

So I came to my Christian faith later in life, and it was because the precepts of Jesus Christ spoke to me in terms of the kind of life that I would want to lead. Jesus Christ dying for my sins spoke to the humility we all have to have as human beings, that we're sinful and we're flawed and we make mistakes, and that we achieve salvation through the grace of God.

One of the things I've learned about being president is that we'll work on issues for long periods of time, sometimes in obscurity.
