John F. Kennedy Quotes

We in this country, in this generation, are — by destiny rather than choice — the watchmen on the walls of world freedom. We ask, therefore, that we may be worthy of our power and responsibility, that we may exercise our strength with wisdom and restraint, and that we may achieve in our time and for all time the ancient vision of "peace on earth, good will toward men". That must always be our goal, and the righteousness of our cause must always underlie our strength. For as was written long ago: "except the Lord keep the city, the watchman waketh but in vain."

Our adversaries have not abandoned their ambitions, our dangers have not diminished, our vigilance cannot be relaxed. But now we have the military, the scientific, and the economic strength to do whatever must be done for the preservation and promotion of freedom. That strength will never be used in pursuit of aggressive ambitions — it will always be used in pursuit of peace. It will never be used to promote provocations — it will always be used to promote the peaceful settlement of disputes.

Finally, it should be clear by now that a nation can be no stronger abroad than she is at home. Only an America which practices what it preaches about equal rights and social justice will be respected by those whose choice affects our future. Only an America which has fully educated its citizens is fully capable of tackling the complex problems and perceiving the hidden dangers of the world in which we live. And only an America which is growing and prospering economically can sustain the worldwide defenses of freedom, while demonstrating to all concerned the opportunities of our system and society.

Our foreign aid program is not growing in size, it is, on the contrary, smaller now than in previous years. It has had its weaknesses, but we have undertaken to correct them. And the proper way of treating weaknesses is to replace them with strength, not to increase those weaknesses by emasculating essential programs. Dollar for dollar, in or out of government, there is no better form of investment in our national security than our much-abused foreign aid program.

Our security and strength, in the last analysis, directly depend on the security and strength of others, and that is why our military and economic assistance plays such a key role in enabling those who live on the periphery of the Communist world to maintain their independence of choice. Our assistance to these nations can be painful, risky and costly, as is true in Southeast Asia today. But we dare not weary of the task. For our assistance makes possible the stationing of 3-5 million allied troops along the Communist frontier at one-tenth the cost of maintaining a comparable number of American soldiers.

In this administration also it has been necessary at times to issue specific warnings — warnings that we could not stand by and watch the Communists conquer Laos by force, or intervene in the Congo, or swallow West Berlin, or maintain offensive missiles on Cuba. But while our goals were at least temporarily obtained in these and other instances, our successful defense of freedom was due not to the words we used, but to the strength we stood ready to use on behalf of the principles we stand ready to defend. This strength is composed of many different elements, ranging from the most massive deterrents to the most subtle influences. And all types of strength are needed — no one kind could do the job alone.

I want to discuss with you today the status of our strength and our security because this question clearly calls for the most responsible qualities of leadership and the most enlightened products of scholarship. For this Nation's strength and security are not easily or cheaply obtained, nor are they quickly and simply explained. There are many kinds of strength and no one kind will suffice. Overwhelming nuclear strength cannot stop a guerrilla war. Formal pacts of alliance cannot stop internal subversion. Displays of material wealth cannot stop the disillusionment of diplomats subjected to discrimination. Above all, words alone are not enough. The United States is a peaceful nation. And where our strength and determination are clear, our words need merely to convey conviction, not belligerence. If we are strong, our strength will speak for itself. If we are weak, words will be of no help.

We cannot expect that everyone, to use the phrase of a decade ago, will "talk sense to the American people". But we can hope that fewer people will listen to nonsense. And the notion that this Nation is headed for defeat through deficit, or that strength is but a matter of slogans, is nothing but just plain nonsense.

It is fitting that these two symbols of Dallas progress are united in the sponsorship of this meeting, for they represent the best qualities, I am told, of leadership and learning in this city — and leadership and learning are indispensable to each other. The advancement of learning depends on community leadership for financial and political support and the products of that learning, in turn, are essential to the leadership's hopes for continued progress and prosperity. It is not a coincidence that those communities possessing the best in research and graduate facilities — from MIT to Cal Tech — tend to attract the new and growing industries. [...] This link between leadership and learning is not only essential at the community level, it is even more indispensable in world affairs. Ignorance and misinformation can handicap the progress of a city or a company, but they can, if allowed to prevail in foreign policy, handicap this country's security. In a world of complex and continuing problems, in a world full of frustrations and irritations, America's leadership must be guided by the lights of learning and reason, or else those who confuse rhetoric with reality and the plausible with the possible will gain the popular ascendancy with their seemingly swift and simple solutions to every world problem.

This Nation has tossed its cap over the wall of space, and we have no choice but to follow it. Whatever the difficulties, they will be overcome. Whatever the hazards, they must be guarded against. With the vital help of this Aerospace Medical Center, with the help of all those who labor in the space endeavor, with the help and support of all Americans, we will climb this wall with safety and with speed-and we shall then explore the wonders on the other side.

Frank O'Connor, the Irish writer, tells in one of his books how, as a boy, he and his friends would make their way across the countryside, and when they came to an orchard wall that seemed too high and too doubtful to try and too difficult to permit their voyage to continue, they took off their hats and tossed them over the wall — and then they had no choice but to follow them.

I think the United States should be a leader. A country as rich and powerful as this which bears so many burdens and responsibilities, which has so many opportunities, should be second to none. And in December, while I do not regard our mastery of space as anywhere near complete, while I recognize that there are still areas where we are behind — at least in one area, the size of the booster — this year I hope the United States will be ahead. And I am for it. We have a long way to go. Many weeks and months and years of long, tedious work lie ahead. There will be setbacks and frustrations and disappointments. There will be, as there always are, pressures in this country to do less in this area as in so many others, and temptations to do something else that is perhaps easier. But this research here must go on. This space effort must go on. The conquest of space must and will go ahead. That much we know. That much we can say with confidence and conviction.

And third, medical space research may lead to new safeguards against hazards common to many environments. Specifically, our astronauts will need fundamentally new devices to protect them from the ill effects of radiation which can have a profound influence upon medicine and man's relations to our present environment.

And second, medical space research may revolutionize the technology and the techniques of modern medicine. Whatever new devices are created, for example, to monitor our astronauts, to measure their heart activity, their breathing, their brain waves, their eye motion, at great distances and under difficult conditions, will also represent a major advance in general medical instrumentation. Heart patients may even be able to wear a light monitor which will sound a warning if their activity exceeds certain limits. An instrument recently developed to record automatically the impact of acceleration upon an astronaut's eyes will also be of help to small children who are suffering miserably from eye defects, but are unable to describe their impairment. And also by the use of instruments similar to those used in Project Mercury, this Nation's private as well as public nursing services are being improved, enabling one nurse now to give more critically ill patients greater attention than they ever could in the past.

I give you three examples: first, medical space research may open up new understanding of man's relation to his environment. Examinations of the astronaut's physical, and mental, and emotional reactions can teach us more about the differences between normal and abnormal, about the causes and effects of disorientation, about changes in metabolism which could result in extending the life span. When you study the effects on our astronauts of exhaust gases which can contaminate their environment, and you seek ways to alter these gases so as to reduce their toxicity, you are working on problems similar to those in our great urban centers which themselves are being corrupted by gases and which must be clear.
