Military and economic assistance has been a heavy burden on our citizens for a long time, and I recognize the strong pressures against it; but this b… - John F. Kennedy

The great enemy of the truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

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.

No one should be under the illusion that negotiations for the sake of negotiations always advance the cause of peace. If for lack of preparation they break up in bitterness, the prospects of peace have been endangered. If they are made a forum for propaganda or a cover for aggression, the processes of peace have been abused. But it is a test of our national maturity to accept the fact that negotiations are not a contest spelling victory or defeat. They may succeed — they may fail. They are likely to be successful only if both sides reach an agreement which both regard as preferable to the status quo — an agreement in which each side can consider its own situation to be improved. And this is most difficult to obtain. But, while we shall negotiate freely, we shall not negotiate freedom. Our answer to the classic question of Patrick Henry is still no-life is not so dear, and peace is not so precious, "as to be purchased at the price of chains and slavery." And that is our answer even though, for the first time since the ancient battles between Greek city-states, war entails the threat of total annihilation, of everything we know, of society itself. For to save mankind's future freedom, we must face up to any risk that is necessary. We will always seek peace — but we will never surrender.
