Commemorate.

The United States and the freedom for which it stands, the freedom for which they died, must endure and prosper. Their lives remind us that freedom is not bought cheaply. It has a cost; it imposes a burden. And just as they whom we commemorate were willing to sacrifice, so too must we—in a less final, less heroic way—be willing to give of ourselves ...

I can't claim to know the words of all the national anthems in the world, but I don't know of any other that ends with a question and a challenge as ours does: Does that flag still wave o'er the land of the free and the home of the brave? That is what we must all ask.
