We stand today on the edge of a new frontier. But the new frontierof which I speak isnot a set of promises.It is a set of challenges. It sums up not what I intend to offer the American people, but what I intend to ask of them. It appeals to their pride, not their pocketbooköit holds out the promise of more sacrifice instead of more security.

-Kennedy,John F(itzgerald)
