“If words can be lethal weapons, I must provide them with an arsenal.”

1980s, First term of office (1981–1985), First Inaugural address (1981)
Context: Above all, we must realize that no arsenal or no weapon in the arsenals of the world is so formidable as the will and moral courage of free men and women. It is a weapon our adversaries in today's world do not have. It is a weapon that we as Americans do have. Let that be understood by those who practice terrorism and prey upon their neighbors.

Context: There are many persons of combative tendencies, who read for ammunition, and dig out of the Bible iron for balls. They read, and they find nitre and charcoal and sulphur for powder. They read, and they find cannon. They read, and they make portholes and embrasures. And if a man does not believe as they do, they look upon him as an enemy, and let fly the Bible at him to demolish him. So men turn the word of God into a vast arsenal, filled with all manner of weapons, offensive and defensive.

Context: It is with appreciation and gratefulness that I accept from you this scroll for the Los Alamos Laboratory, and for the men and women whose work and whose hearts have made it. It is our hope that in years to come we may look at the scroll and all that it signifies, with pride. Today that pride must be tempered by a profound concern. If atomic bombs are to be added as new weapons to the arsenals of a warring world, or to the arsenals of the nations preparing for war, then the time will come when mankind will curse the names of Los Alamos and Hiroshima. The people of this world must unite or they will perish. This war that has ravaged so much of the earth, has written these words. The atomic bomb has spelled them out for all men to understand. Other men have spoken them in other times, and of other wars, of other weapons. They have not prevailed. There are some misled by a false sense of human history, who hold that they will not prevail today. It is not for us to believe that. By our minds we are committed, committed to a world united, before the common peril, in law and in humanity.
