But life is never easy. There is work to be done and obligations to be met — obligations to truth, to justice, and to liberty. - John F. Kennedy

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.

I want to point out that we have increased in conventional forces in the last 2 years the number of our divisions from 11 to 16, and we are also providing equipment for 22 divisions in case it were necessary to mobilize our Guard. We have six divisions in Europe, and we have the equipment for two more. Now, I think the Cuban incident indicated the importance of a strong conventional force. The greatest factor on our side was the fact that we had superior conventional strength on the scene, and it would have been necessary to equalize that strength for the Soviets to initiate the use of nuclear weapons, which of course they were quite reluctant to do.

We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.
