In the age of nuclear warfare to continue our political differences by means of war would be to discontinue civilization as we know it. War is an option whose time has passed. Peace is the only option for the future. At present we occupy a treacherous no-man’s-land between peace and war, a time of growing fear that our military might has expanded beyond our capacity to control it and our political differences widened beyond our ability to bridge them.

We've got to move on to the point of seeing that on the international scale, war is obsolete -- that it must somehow be cast into unending limbo. But in a day when Sputniks and Explorers are dashing through outer space and guided ballistic missiles are carving highways of death through the stratosphere, no nation can win a war. It is no longer a choice between violence and nonviolence; it is either nonviolence or nonexistence. And the alternative to disarmament, the alternative to a greater suspension of nuclear tests, the alternative to strengthening the United Nations and thereby disarming the whole world may well be a civilization plunged into the abyss of annihilation. And so we must rise up and beat our swords into plowshares, and our spears into pruning hooks and nations must not rise up against nations, neither must they study war anymore.

War is obsolete. It could never have been done before. Only ten years ago... technology reached the point where it could be done. Since then the invisible technological-capability revolution has made it ever easier so to do.

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.

Either war is obsolete or men are.

In war, science has proven itself an evil genius; it has made war more terrible than it ever was before. Man used to be content to slaughter his fellowmen on a single plane — the earth's surface. Science has taught him to go down into the water and shoot up from below and to go up into the clouds and shoot down from above, thus making the battlefield three times a bloody as it was before; but science does not teach brotherly love. Science has made war so hellish that civilization was about to commit suicide; and now we are told that newly discovered instruments of destruction will make the cruelties of the late war seem trivial in comparison with the cruelties of wars that may come in the future.

Eighteen years ago the advent of nuclear weapons changed the course of the world as well as the war. Since that time, all mankind has been struggling to escape from the darkening prospect of mass destruction on earth. In an age when both sides have come to possess enough nuclear power to destroy the human race several times over, the world of communism and the world of free choice have been caught up in a vicious circle of conflicting ideology and interest. Each increase of tension has produced an increase of arms; each increase of arms has produced an increase of tension.

We invite this Congress, and through it the scientists of the world and the general public, to subscribe to the following resolution: "In view of the fact that in any future world war nuclear weapons will certainly be employed, and that such weapons threaten the continued existence of mankind, we urge the governments of the world to realize, and to acknowledge publicly, that their purpose cannot be furthered by a world war, and we urge them, consequently, to find peaceful means for the settlement of all matters of dispute between them".

If our squawking pacifists were rational, they would perceive that war can be ended only by abolishing the several species of mammals called human; our spacecraft have shown us that Mars and Venus are perfectly warless worlds.

There have been, from time to time, changes in the degree of destructiveness of weapons and of war. These changes, until recent decades, generally have been considered not to have invalidated the precepts of Western civilization and its antecedent cultures of the moral obligation to defend its freedoms, diversity, and cultural growth from tyranny, reaction, and cultural stagnation or death. But with the advent of the nuclear age, we are faced with a change in degree that threatens to become one of kind. The destructive nature of nuclear war dictates that we no longer regard war as merely the continuation of policy by other means. The deterrence of nuclear war, until such time as technology provides a more reliable and stable method, must, for the United States, be based upon the capability to prevail if deterrence should fail. But this must be combined with an effort to join with other nations in the creation of a just international order.

We're now living in a new world. And end has been put to the cold war and to the arms race, as well as to the mad militarization of the country, which has crippled our economy, public attitudes and morals. The threat of nuclear war has been removed.

Humanity wants no more war.

War is a survival among us from savage times and affects now chiefly the boyish and unthinking element of the nation. The wisest realize that there are better ways for practicing heroism and other and more certain ends of insuring the survival of the fittest. It is something a people outgrow. But whether they consciously practice peace or not, nature in its evolution eventually practices it for them, and after enough of the inhabitants of a globe have killed each other off, the remainder must find it more advantageous to work together for the common good.

All war is absurd. For thousands of years, human beings have chosen to settle their differences by obliterating one another. And when we are not obliterating one another, we spend an enormous amount of time and attention coming up with better ways to obliterate one another the next time around. It’s all a little strange, if you think about it.
