I then spoke to chancellor (Angela) Merkel of Germany and we agreed that the United States and our European allies will work closely together in the weeks and months ahead.

Ultimately, only diplomacy can bring about a durable solution to the challenge posed by Iran's nuclear program. As President and Commander in Chief, I will do what is necessary to prevent Iran from obtaining a nuclear weapon. However, I have a profound responsibility to try to resolve our differences peacefully, rather than rush towards conflict.

Under my plan of a cap and trade system, electricity rates would necessarily skyrocket… Because I’m capping greenhouse gasses, coal power plants, natural gas…you name it…whatever the plants were, whatever the industry was, they would have to retro-fit their operations. That will cost money…they will pass that money on to the consumers.

We know we can't stop every act of violence, every act of evil in the world, but maybe we could try to stop one act of evil, one act of violence.

And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to the suffering outside our borders; nor can we consume the world's resources without regard to effect. For the world has changed, and we must change with it.

For now, whether you are young or whether you're young at heart, I do have one final ask of you as your president, the same thing I asked when you took a chance on me eight years ago. I am asking you to believe not in my ability to bring about change, but in yours.

In the eyes of God, a child on the other side of the border is no less worthy of love and compassion than my own child. We - we can't distinguish between them in terms of their worth and their inherent dignity and that they're deserving of shelter and love and education and opportunity. We can't isolate ourselves. We can't hide behind a wall.
