Let me also address the issue of Iraq. Unlike Afghanistan, Iraq was a war of choice that provoked strong differences in my country and around the world. Although I believe that the Iraqi people are ultimately better off without the tyranny of Saddam Hussein, I also believe that events in Iraq have reminded America of the need to use diplomacy and build international consensus to resolve our problems whenever possible. Indeed, we can recall the words of Thomas Jefferson, who said: "I hope that our wisdom will grow with our power, and teach us that the less we use our power the greater it will be."

Today, America has a dual responsibility: to help Iraq forge a better future - and to leave Iraq to Iraqis. I have made it clear to the Iraqi people that we pursue no bases, and no claim on their territory or resources. Iraq's sovereignty is its own. That is why I ordered the removal of our combat brigades by next August. That is why we will honor our agreement with Iraq's democratically-elected government to remove combat troops from Iraqi cities by July, and to remove all our troops from Iraq by 2012. We will help Iraq train its Security Forces and develop its economy. But we will support a secure and united Iraq as a partner, and never as a patron.

And finally, just as America can never tolerate violence by extremists, we must never alter our principles. 9/11 was an enormous trauma to our country. The fear and anger that it provoked was understandable, but in some cases, it led us to act contrary to our ideals. We are taking concrete actions to change course. I have unequivocally prohibited the use of torture by the United States, and I have ordered the prison at Guantanamo Bay closed by early next year.

So America will defend itself respectful of the sovereignty of nations and the rule of law. And we will do so in partnership with Muslim communities which are also threatened. The sooner the extremists are isolated and unwelcome in Muslim communities, the sooner we will all be safer.
