We do not want to fight — but we have fought before. And others in earlier times have made the same dangerous mistake of assuming that the West was t… - John F. Kennedy

Peace is not solely a matter of military or technical problems — it is primarily a problem of politics and people. And unless man can match his strides in weaponry and technology with equal strides in social and political development, our great strength, like that of the dinosaur, will become incapable of proper control — and like the dinosaur vanish from the earth.

Theodore Roosevelt once said that the White House is a great pulpit from which to preach, and I would like to preach not only the vigorous life which he preached for us physically, but also for us in our time, facing entirely different problems, to make the same wise, vigorous decisions which he made for the conservation of our natural resources so that you and your children can enjoy this great and rich country. Nature has been so generous to us that we have mistreated her. Now, when our country is becoming increasingly crowded, when science and technology wastes so much of what we have, we have to realize that time is running out for us.

Finally, my fellow Americans, let us examine our attitude toward peace and freedom here at home. The quality and spirit of our own society must justify and support our efforts abroad. We must show it in the dedication of our own lives--as many of you who are graduating today will have a unique opportunity to do, by serving without pay in the Peace Corps abroad or in the proposed National Service Corps here at home. But wherever we are, we must all, in our daily lives, live up to the age-old faith that peace and freedom walk together. In too many of our cities today, the peace is not secure because the freedom is incomplete. It is the responsibility of the executive branch at all levels of government--local, State, and National--to provide and protect that freedom for all of our citizens by all means within their authority. It is the responsibility of the legislative branch at all levels, wherever that authority is not now adequate, to make it adequate. And it is the responsibility of all citizens in all sections of this country to respect the rights of all others and to respect the law of the land. All this is not unrelated to world peace. "When a man's ways please the Lord," the Scriptures tell us, "he maketh even his enemies to be at peace with him."
