Science is important, but so is ethics, so is balancing life. To destroy life to save life - it's one of the real ethical dilemmas that we face.

I regret that we weren't able to reform Social Security. The fact that we weren't able to when we had majorities in the House and the Senate I think reflected poorly on our political party.

Thousands of lives were suddenly ended by evil, despicable acts of terror. The pictures of airplanes flying into buildings, fires burning, huge structures collapsing, have filled us with disbelief, terrible sadness and a quiet, unyielding anger.

Immigrants bring to America the values of faith in God, love of family, hard work and self reliance - the values that made us a great nation to begin with. We've all seen those values in action, through the service and sacrifice of more than 35,000 foreign-born men and women currently on active duty in the United States military.

I hope that's what the taxpayers of Great Britain expect, is expect us to, when we make investments in countries, that they work. And they don't work if a nation doesn't invest in its people.

If our commanders on the ground say we need more troops, I will send them. But our commanders tell me they have the number of troops they need to do their job. Sending more Americans would undermine our strategy of encouraging Iraqis to take the lead in this fight. And sending more Americans would suggest that we intend to stay forever, when we are, in fact, working for the day when Iraq can defend itself and we can leave.

You subscribe politics to it. I subscribe freedom to it.
