So long as I'm the president, we will. I clearly see the challenge. I see the challenge of what these threats pose to our homeland, and I see the challenge of what these threats pose to the world.

The key thing about life is to be true to a set of beliefs. And to be genuine.

I'm also not very analytical. You know I don't spend a lot of time thinking about myself, about why I do things.

I'm sure something will pop into my head here in the midst of this press conference, with all the pressure of trying to come up with an answer, but it hadn't yet.

Tonight, I ask for your prayers for all those who grieve, for the children whose worlds have been shattered, for all whose sense of safety and security has been threatened. And I pray they will be comforted by a power greater than any of us, spoken through the ages in Psalm 23: "Even though I walk through the valley of the shadow of death, I fear no evil, for You are with me."

For decades, free nations tolerated oppression in the Middle East for the sake of stability. In practice, this approach brought little stability and much oppression, so I have changed this policy.

As a matter of fact, it's in our interests that we help reformers across the Middle East achieve their objectives. This is the fundamental challenge of the 21st century.
