As we consider the road that unfolds before us, we remember with humble gratitude those brave Americans who, at this very hour, patrol far-off deserts and distant mountains. They have something to tell us today, just as the fallen heroes who lie in Arlington whisper through the ages.
We honor them not only because they are guardians of our liberty, but because they embody the spirit of service; a willingness to find meaning in something greater than themselves. And yet, at this moment — a moment that will define a generation — it is precisely this spirit that must inhabit us all.
For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies.
