If the fallen could speak to us, what would they say? Would they console us? Perhaps they might say that while they could not know they'd be called upon to storm a beach through a hail of gunfire, they were willing to give up everything for the defense of our freedom; that while they could not know they'd be called upon to jump into the mountains of Afghanistan and seek an elusive enemy, they were willing to sacrifice all for their country; that while they couldn't possibly know they would be called to leave this world for another, they were willing to take that chance to save the lives of their brothers and sisters in arms.

What is thing, this sense of duty? What tugs at a person until he or she says "Send me"? Why, in an age when so many have acted only in pursuit of the narrowest self-interest, have the soldiers, sailors, airmen and Marines of this generation volunteered all that they have on behalf of others? Why have they been willing to bear the heaviest burden?

Whatever it is, they felt some tug; they answered a call; they said "I'll go." That is why they are the best of America, and that is what separates them from those of us who have not served in uniform -- their extraordinary willingness to risk their lives for people they never met.

My grandfather served in Patton's Army in World War II. But I cannot know what it is like to walk into battle. I'm the father of two young girls -- but I can't imagine what it's like to lose a child. These are things I cannot know. But I do know this: I am humbled to be the Commander-in-Chief of the finest fighting force in the history of the world. (Applause.)

I know that there is nothing I will not do to keep our country safe, even as I face no harder decision than sending our men and women to war -- and no moment more difficult than writing a letter to the families of the fallen. And that's why as long as I am President, I will only send our troops into harm's way when it is absolutely necessary, and I will always provide them with the equipment and support they need to get the job done. (Applause.)

I know that military families sacrifice more than we can understand, and feel an absence greater than we can comprehend. And that's why Michelle and I are committed to easing their burden.

And I know what a grateful nation owes to those who serve under its proud flag. And that's why I promise all our servicemen and women that when the guns fall silent, and you do return home, it will be to an America that is forever here for you, just as you've been there for us. (Applause.)

With each death, we are heartbroken. With each death, we grow more determined. This bustling graveyard can be a restless place for the living, where solace sometimes comes only from meeting others who know similar grief. But it reminds us all the meaning of valor; it reminds us all of our own obligations to one another; it recounts that most precious aspect of our history, and tells us that we will only rise or fall together.

So on this day of silent remembrance and solemn prayer I ask all Americans, wherever you are, whoever you're with, whatever you're doing, to pause in national unity at 3:00 this afternoon. I ask you to ring a bell, or offer a prayer, say a silent "thank you." And commit to give something back to this nation -- something lasting -- in their memory; to affirm in our own lives and advance around the world those enduring ideals of justice, equality, and opportunity for which they and so many generations of Americans have given that last full measure of devotion.

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