The main burden of local defense against local attack, subversion, insurrection or guerrilla warfare must of necessity rest with local forces. Where … - John F. Kennedy

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.

The effort to improve the conditions of man, however, is not a task for the few. It is the task of all nations — acting alone, acting in groups, acting in the United Nations, for plague and pestilence, and plunder and pollution, the hazards of nature, and the hunger of children are the foes of every nation. The earth, the sea, and the air are the concern of every nation. And science, technology, and education can be the ally of every nation. Never before has man had such capacity to control his own environment, to end thirst and hunger, to conquer poverty and disease, to banish illiteracy and massive human misery. We have the power to make this the best generation of mankind in the history of the world — or to make it the last.

I speak of peace because of the new face of war. Total war makes no sense in an age when great powers can maintain large and relatively invulnerable nuclear forces and refuse to surrender without resort to those forces. It makes no sense in an age when a single nuclear weapon contains almost ten times the explosive force delivered by all the allied air forces in the Second World War. It makes no sense in an age when the deadly poisons produced by a nuclear exchange would be carried by wind and water and soil and seed to the far corners of the globe and to generations yet unborn. Today the expenditure of billions of dollars every year on weapons acquired for the purpose of making sure we never need to use them is essential to keeping the peace. But surely the acquisition of such idle stockpiles — which can only destroy and never create — is not the only, much less the most efficient, means of assuring peace. I speak of peace, therefore, as the necessary rational end of rational men. I realize that the pursuit of peace is not as dramatic as the pursuit of war — and frequently the words of the pursuer fall on deaf ears. But we have no more urgent task.
