Before you put the final touches on Senator Obama's speech, it's still not too late to crib from Bill Kristol's column suggesting that the the senator might want to follow in JFK's footsteps and talk about achieving victory:

Speaking on behalf of “the world of freedom,” Kennedy challenged the anti-anti-Communists and the peaceniks. He chastised the “many people in the world who really don’t understand, or say they don’t, what is the great issue between the free world and the Communist world.” He rebuked those “who say in Europe and elsewhere we can work with the Communists.” To all of them, Kennedy memorably said: “Let them come to Berlin.”

Perhaps Obama — with the Victory Column at his back — will also challenge those who think it impossible to imagine victory today. Perhaps Obama will also warn of the temptation of assuming we can somehow avoid confronting the terrorists and jihadists, and those who support them.
