On Iraq, on paper, there's not as much difference, I think, between the Bush administration and a Kerry administration as there would have been a yea… - Barack Obama

Let me be absolutely clear: Iran is a grave threat.

We do not have to think that human nature is perfect for us to still believe that the human condition can be perfected. We do not have to live in an idealized world to still reach for those ideals that will make it a better place. The non-violence practiced by men like Gandhi and King may not have been practical or possible in every circumstance, but the love that they preached — their fundamental faith in human progress — that must always be the North Star that guides us on our journey. For if we lose that faith — if we dismiss it as silly or naïve; if we divorce it from the decisions that we make on issues of war and peace — then we lose what's best about humanity. We lose our sense of possibility. We lose our moral compass. Like generations have before us, we must reject that future. As Dr. King said at this occasion so many years ago, "I refuse to accept despair as the final response to the ambiguities of history. I refuse to accept the idea that the 'isness' of man's present condition makes him morally incapable of reaching up for the eternal 'oughtness' that forever confronts him." Let us reach for the world that ought to be — that spark of the divine that still stirs within each of our souls.

To all of you who served in Afghanistan, you can take enormous pride in the progress you helped achieve: Driving al Qaeda out of its camps. Toppling the Taliban. Delivering justice to Osama bin Laden. Helping Afghans improve their lives. There are millions of boys and girls in school, and democratic elections and a democratic government. Training Afghan forces to take responsibility for their own security so that we are no longer engaged in a major ground war in Afghanistan. That is your legacy. And today we salute our forces serving there on a more limited mission -- supporting Afghan forces, going after terrorists -- because we must never allow Afghanistan to be used as a safe haven for terrorists to attack our nation again.
