I regret the fact that Saddam [Hussein] didn't have weapons of mass destruction that we thought. I don't regret removing him from power.

I am very comfortable with the strategic decisions that I made.

I think we're making progress. We understand where the power of this country lay. It lies in the hearts and souls of Americans. It must lay in our pocketbooks. It lies in the willingness for people to work hard.

An all-volunteer army is best suited to fight the new wars of the 21st century.

But I'm mindful in a free society that people can worship if they want to or not. You're equally an American if you choose to worship an Almighty and if you choose not to. If you're a Christian, Jew or Muslim you're equally an American. That's the great thing about America is the right to worship the way you see fit. Prayer and religion sustain me. I receive calmness in the storms of the presidency. I love the fact that people pray for me and my family all around the country. Somebody asked me one time, how do you know? I said I just feel it.

I think if you know what you believe, it makes it a lot easier to answer questions. I can't answer your question.

When our children and grandchildren look back on this period, one question will overwhelm all the rest: Did we do everything in our power to fight and to win the war on terror? That's the fundamental question this generation faces.
