But perhaps the most profound issue surrounding my receipt of this prize is the fact that I am the Commander-in-Chief of the military of a nation in the midst of two wars. One of these wars is winding down. The other is a conflict that America did not seek; one in which we are joined by 42 other countries -- including Norway -- in an effort to defend ourselves and all nations from further attacks.
Where force is necessary, we have a moral and strategic interest in binding ourselves to certain rules of conduct. And even as we confront a vicious adversary that abides by no rules, I believe the United States of America must remain a standard bearer in the conduct of war. That is what makes us different from those whom we fight. That is a source of our strength.
As someone who stands here as a direct consequence of Dr. King's life work, I am living testimony to the moral force of non-violence. I know there's nothing weak, nothing passive, nothing naive, in the creed and lives of Gandhi and King. But as a head of state sworn to protect and defend my nation, I cannot be guided by their examples alone. I face the world as it is, and cannot stand idle in the face of threats to the American people. For make no mistake: Evil does exist in the world. A non-violent movement could not have halted Hitler's armies. Negotiations cannot convince al Qaeda's leaders to lay down their arms. To say that force may sometimes be necessary is not a call to cynicism, it is a recognition of history; the imperfections of man and the limits of reason.
But the world must remember that it was not simply international institutions, not just treaties and declarations that brought stability to a post-World War II world. Whatever mistakes we have made, the plain fact is this: The United States of America has helped underwrite global security for more than six decades with the blood of our citizens and the strength of our arms. The service and sacrifice of our men and women in uniform has promoted peace and prosperity from Germany to Korea, and enabled democracy to take hold in places like the Balkans. We have borne this burden not because we seek to impose our will. We have done so out of enlightened self-interest, because we seek a better future for our children and grandchildren, and we believe that their lives will be better if others' children and grandchildren can live in freedom and prosperity.
For peace is not merely the absence of visible conflict. Only a just peace based on the inherent rights and dignity of every individual can truly be lasting. It was this insight that drove drafters of the Universal Declaration of Human Rights after the Second World War. In the wake of devastation, they recognized that if human rights are not protected, peace is a hollow promise.
Somewhere today, in the here and now, in the world as it is, a soldier sees he's outgunned, but stands firm to keep the peace. Somewhere today, in this world, a young protestor awaits the brutality of her government, but has the courage to march on. Somewhere today, a mother facing punishing poverty still takes the time to teach her child, scrapes together what few coins she has to send that child to school, because she believes that a cruel world still has a place for that child's dreams. Let us live by their example. We can acknowledge that oppression will always be with us, and still strive for justice.
At times, it even feels like we're moving backwards. We see it in the Middle East, as the conflict between Arabs and Jews seems to harden. We see it in nations that are torn asunder by tribal lines. And most dangerously, we see it in the way that religion is used to justify the murder of innocents by those who have distorted and defiled the great religion of Islam, and who attacked my country from Afghanistan. These extremists are not the first to kill in the name of God; the cruelties of the Crusades are amply recorded. But they remind us that no Holy War can ever be a just war. For if you truly believe that you are carrying out divine will, then there is no need for restraint -- no need to spare the pregnant mother, or the medic, or the Red Cross worker, or even a person of one's own faith. Such a warped view of religion is not just incompatible with the concept of peace, but I believe it's incompatible with the very purpose of faith for the one rule that lies at the heart of every major religion is that we do unto others as we would have them do unto us.
I believe that force can be justified on humanitarian grounds, as it was in the Balkans, or in other places that have been scarred by war. Inaction tears at our conscience and can lead to more costly intervention later. That's why all responsible nations must embrace the role that militaries with a clear mandate can play to keep the peace.
And over time, as codes of law sought to control violence within groups, so did philosophers and clerics and statesmen seek to regulate the destructive power of war. The concept of a "just war" emerged, suggesting that war is justified only when certain conditions were met: if it is waged as a last resort or in self-defense; if the force used is proportional; and if, whenever possible, civilians are spared from violence. Of course, we know that for most of history, this concept of "just war" was rarely observed. The capacity of human beings to think up new ways to kill one another proved inexhaustible, as did our capacity to exempt from mercy those who look different or pray to a different God.
To begin with, I believe that all nations, strong and weak alike, must adhere to standards that govern the use of force. I, like any head of state, reserve the right to act unilaterally if necessary to defend my nation. Nevertheless, I am convinced that adhering to standards, international standards, strengthens those who do, and isolates and weakens those who don't.
The Cold War ended with jubilant crowds dismantling a wall. Commerce has stitched much of the world together. Billions have been lifted from poverty. The ideals of liberty and self-determination, equality and the rule of law have haltingly advanced. We are the heirs of the fortitude and foresight of generations past, and it is a legacy for which my own country is rightfully proud.
