John F. Kennedy

JFK: (Speech at the University of Washington, Seattle, November 16, 1961) In short, we must face problems which do not lend themselves to easy or quick or permanent solutions. And we must face the fact that the United States is neither omnipotent nor omniscient, that we are only six percent of the world's population, that we cannot impose our will upon the other ninety-four percent of mankind, that we cannot right every wrong or reverse each adversity, and that therefore there cannot be an American solution to every world problem.

JFK: (Acceptance Speech as the Democratic presidential nominee, July 15, 1960) The New Frontier of which I speak is not 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.

JFK: (May 25, 1961) I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish.
