This link between leadership and learning is 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.  

There will always be dissident voices heard in the land, expressing opposition without alternatives, finding fault but never favor, perceiving gloom on every side and seeking influence without responsibility. Those voices are inevitable. 

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.  

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. 

It was not the Monroe Doctrine that kept all Europe away from this hemisphere — it was the strength of the British fleet and the width of the Atlantic Ocean. It was not General Marshall’s speech at Harvard which kept communism out of Western Europe — it was the strength and stability made possible by our military and economic assistance. 

Our 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.  

The strategic nuclear power of the United States has been so greatly modernized and expanded in the last 1,000 days, by the rapid production and deployment of the most modern missile systems, that any and all potential aggressors are clearly confronted now with the impossibility of strategic victory — and the certainty of total destruction — if by reckless attack they should ever force upon us the necessity of a strategic reply. 

American military might should not and need not stand alone against the ambitions of international communism. Our security and strength 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.  

Freedom can be lost without a shot being fired, by ballots as well as bullets. The success of our leadership is dependent upon respect for our mission in the world as well as our missiles — on a clearer recognition of the virtues of freedom as well as the evils of tyranny. 

We have regained the initiative in the exploration of outer space, making it clear to all that the United States of America has no intention of finishing second in space. 

This effort is expensive — but it pays its own way, for freedom and for America.  

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. 

America’s 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. 

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.” 

These are the abridged and slightly edited remarks President Kennedy would have delivered on November 22 had he not been assassinated by Lee Harvey Oswald.
