The theory of independence is as old as man himself, and it was not invented in this hall. But it was in this hall that the theory became a practice;… - John F. Kennedy

But as long as we know what comprises our vital interests and our long-range goals, we have nothing to fear from negotiations at the appropriate time, and nothing to gain by refusing to take part in them. At a time when a single clash could escalate overnight into a holocaust of mushroom clouds, a great power does not prove its firmness by leaving the task of exploring the other's intentions to sentries or those without full responsibility. Nor can ultimate weapons rightfully be employed, or the ultimate sacrifice rightfully demanded of our citizens, until every reasonable solution has been explored. "How many wars," Winston Churchill has written, "have been averted by patience and persisting good will! .... How many wars have been precipitated by firebrands!"

In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility — I welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it — and the glow from that fire can truly light the world. And so, my fellow Americans: ask not what your country can do for you — ask what you can do for your country. My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.

When I ran for Presidency of the United States, I knew that this country faced serious challenges, but I could not realize — nor could any man realize who does not bear the burdens of this office — how heavy and constant would be those burdens.
