Both sides may be sincere in their views, but neither side is right. The American people are not absolutist, and they don't elect us to impose a rigid ideology on our problems. They know that we need not sacrifice our security for our values, nor sacrifice our values for our security, so long as we approach difficult questions with honesty and care and a dose of common sense. That, after all, is the unique genius of America. That's the challenge laid down by our Constitution. That has been the source of our strength through the ages. That's what makes the United States of America different as a nation.

I can stand here today, as President of the United States, and say without exception or equivocation that we do not torture, and that we will vigorously protect our people while forging a strong and durable framework that allows us to fight terrorism while abiding by the rule of law. Make no mistake: If we fail to turn the page on the approach that was taken over the past several years, then I will not be able to say that as President. And if we cannot stand for our core values, then we are not keeping faith with the documents that are enshrined in this hall. (Applause.)

The Framers who drafted the Constitution could not have foreseen the challenges that have unfolded over the last 222 years. But our Constitution has endured through secession and civil rights, through World War and Cold War, because it provides a foundation of principles that can be applied pragmatically; it provides a compass that can help us find our way. It hasn't always been easy. We are an imperfect people. Every now and then, there are those who think that America's safety and success requires us to walk away from the sacred principles enshrined in this building. And we hear such voices today. But over the long haul the American people have resisted that temptation. And though we've made our share of mistakes, required some course corrections, ultimately we have held fast to the principles that have been the source of our strength and a beacon to the world.

Now this generation faces a great test in the specter of terrorism. And unlike the Civil War or World War II, we can't count on a surrender ceremony to bring this journey to an end. Right now, in distant training camps and in crowded cities, there are people plotting to take American lives. That will be the case a year from now, five years from now, and -- in all probability -- 10 years from now. Neither I nor anyone can stand here today and say that there will not be another terrorist attack that takes American lives. But I can say with certainty that my administration -- along with our extraordinary troops and the patriotic men and women who defend our national security -- will do everything in our power to keep the American people safe. And I do know with certainty that we can defeat al Qaeda. Because the terrorists can only succeed if they swell their ranks and alienate America from our allies, and they will never be able to do that if we stay true to who we are, if we forge tough and durable approaches to fighting terrorism that are anchored in our timeless ideals. This must be our common purpose.

I ran for President because I believe that we cannot solve the challenges of our time unless we solve them together. We will not be safe if we see national security as a wedge that divides America -- it can and must be a cause that unites us as one people and as one nation. We've done so before in times that were more perilous than ours. We will do so once again.

Thank you, God bless you, and God bless the United States of America. (Applause.)
