It is a little awkward that Obama is receiving the Nobel Peace Prize just weeks after announcing that he is sending more troops into Afghanistan.  To his credit, he didn't shy away from addressing this elephant in the room when he received the Prize in Norway today:

And yet I would be remiss if I did not acknowledge the considerable controversy that your generous decision has generated. (Laughter.) In part, this is because I am at the beginning, and not the end, of my labors on the world stage. Compared to some of the giants of history who've received this prize — Schweitzer and King; Marshall and Mandela — my accomplishments are slight. And then there are the men and women around the world who have been jailed and beaten in the pursuit of justice; those who toil in humanitarian organizations to relieve suffering; the unrecognized millions whose quiet acts of courage and compassion inspire even the most hardened cynics. I cannot argue with those who find these men and women — some known, some obscure to all but those they help — to be far more deserving of this honor than I.

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.

Still, we are at war, and I'm responsible for the deployment of thousands of young Americans to battle in a distant land. Some will kill, and some will be killed. And so I come here with an acute sense of the costs of armed conflict — filled with difficult questions about the relationship between war and peace, and our effort to replace one with the other.

Now these questions are not new. War, in one form or another, appeared with the first man. At the dawn of history, its morality was not questioned; it was simply a fact, like drought or disease — the manner in which tribes and then civilizations sought which tribes and then civilizations sought power and settled their differences.

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.

***

We must begin by acknowledging the hard truth: We will not eradicate violent conflict in our lifetimes. There will be times when nations — acting individually or in concert — will find the use of force not only necessary but morally justified.

I make this statement mindful of what Martin Luther King Jr. said in this same ceremony years ago: "Violence never brings permanent peace. It solves no social problem: it merely creates new and more complicated ones." 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 naïve — 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.

Basically, he's saying that it's the Nobel Peace Prize, folks, not the Nobel Pacifist Prize… and that war is sometimes necessary to preserve the peace.

Well, I guess he has to say that, and there certainly is an unfortunate truth to what he says.  However, it only highlights the position held by many that Obama may not have been the best choice for the Peace Prize.

I think, however, he shows himself more worthy of the award toward the end of his speech, when he embraces the so-called "Superman theory" of American warfare — i.e., as the world's remaining superpower, we should behave more like Clark Kent rather than Jack Bauer:

Let me make one final point about the use of force. Even as we make difficult decisions about going to war, we must also think clearly about how we fight it. The Nobel Committee recognized this truth in awarding its first prize for peace to Henry Dunant — the founder of the Red Cross, and a driving force behind the Geneva Conventions.

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. That is why I prohibited torture. That is why I ordered the prison at Guantanamo Bay closed. And that is why I have reaffirmed America's commitment to abide by the Geneva Conventions. We lose ourselves when we compromise the very ideals that we fight to defend. (Applause.) And we honor — we honor those ideals by upholding them not when it's easy, but when it is hard.

And moments later:

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. (Applause.)

All in all, I believe it was a good speech that threaded the fine line between acknowledging the world as it is, while aspiring to a world that could be.

UPDATE:  The Rude Pundit makes an interesting observation:

Here's how you know the way things have changed. In his September 14, 2001 speech at a prayer service for 9/11 victims, George W. Bush said that America's "responsibility to history is already clear: to answer these attacks and rid the world of evil." And today, Barack Obama, in contrast, offered a less utopian view of the future: "We must begin by acknowledging the hard truth that we will not eradicate violent conflict in our lifetimes."

That goes back to the leader-as-tough-talking-movie-hero vs. leader-as-realist issue.  Republicans love the former; hate the latter.
