To our sister republics south of our border: we offer a special pledge. . . to convert our good words into good deeds. . .in a new alliance for progress . . .to assist free men and free governments in casting off the chains of poverty. But this peaceful revolution of hope cannot become the prey of hostile powers. Let all our neighbors know that we shall join with them to oppose aggression or subversion anywhere in the Americas. . .and let every other power know that this hemisphere intends to remain the master of its own house. To that world assembly of sovereign states: the United Nations. . . our last best hope in an age where the instruments of war have far outpaced the instruments of peace, we renew our pledge of support. . .to prevent it from becoming merely a forum for invective. . .to strengthen its shield of the new and the weak. . . and to enlarge the area in which its writ may run. Finally, to those nations who would make themselves our adversaries, we offer not a pledge but a request: that both sides begin anew the quest for peace; before the dark powers of destruction unleashed by science engulf all humanity in planned or accidental self-destruction. We dare not tempt them with weakness. For only when our arms are sufficient beyond doubt can we be certain beyond doubt that they will never be employed. But neither can two great and powerful groups of nations take comfort from our present course. . .both sides overburdened by the cost of modern weapons, both rightly alarmed by the steady spread of the deadly atom, yet both racing to alter that uncertain balance of terror that stays the hand of Mankind's final war. So let us begin anew. . .remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear, but let us never fear to negotiate. Let both sides explore what problems unite us instead of belaboring those problems which divide us. Let both sides, for the first time, formulate serious and precise proposals for the inspection and control of arms. . .and bring the absolute power to destroy other nations under the absolute control of all nations. Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce. Let both sides unite to heed in all corners of the earth the command of Isaiah. . .to "undo the heavy burdens. . . let the oppressed go free." And if a beachhead of co-operation may push back the jungle of suspicion. . . let both sides join in creating not a new balance of power. . . but a new world of law. . .where the strong are just. . . and the weak secure. . .and the peace preserved. . . .
