They killed in the name of God. But they are not the first. This began in pre-history; the tragedy is that it persists today.
Some would characterize the events of 9-11 as a clash of civilizations, and a conflict of religions. And to many it seems a simple and satisfying explanation.
But others would suggest, correctly in my view, that such an interpretation is both wrong-headed and dangerous. They recognize a civil war within Islam itself, as contending factions compete for power. They would argue that we must influence the struggle where we can, by supporting greater attention to the secular structures in the Islamic world, and by encouraging our own American Islamic community to speak out in support of America's democratic values.
Ultimately, your generation will have the decisive voice. You will determine whether rage or reason guides the United States in the struggle to come. You will choose whether we are known for revenge or compassion. You will choose whether we, too, will kill in the name of God, or whether in His Name, we can find a higher civilization and a better means of settling our differences.
And this is not a new choice, not for your generation — it is a choice that many others have faced throughout history. Only now, we can hope that with your help and engagement we can find a new answer.

And only as a last resort do you use military force. This president has distorted the capabilities of the United States Armed Forces. He's used our men and women in uniform improperly in Guantanamo and engaged in actions that I think are totally against the Uniform Code of Military Justice and against what we stand for as the American people.

I think it's [torture] a violation of international law and a violation of American law and a violation of the principles of good government in America. There have always been evidences of mistreatment of prisoners... George Washington told his soldiers... “No, treat them well.” He said, “They’ll join our side.” And many of them did. It was a smart policy, not only the right thing to do, but a smart policy to treat the enemy well. We've made countless enemies in that part of the world by the way we've treated people and disregarded them. It's bad, bad policy.
