“The Pacific no longer represents menacing avenues of approach for a prospective invader. It assumes, instead, the friendly aspect of a peaceful lake. Our line of defense is a natural one and can be maintained with a minimum of military effort and expense.”

Greenock, 19 September 1853

The Pathway of Peace (1923)
Context: The only real progress to abiding peace is found in the friendly disposition of peoples and … facilities for maintaining peace are useful only to the extent that this friendly disposition exists and finds expression. War is not only possible, but probable, where mistrust and hatred and desire for revenge are the dominant motives. Our first duty is at home with our own opinion, by education and unceasing effort to bring to naught the mischievous exhortation of chauvinists; our next is to aid in every practicable way in promoting a better feeling among peoples, the healing of wounds, and the just settlement of differences.

Concurring in New York Times Co. v. United States, 403 U.S. 713 (1971).
Context: The word 'security' is a broad, vague generality whose contours should not be invoked to abrogate the fundamental law embodied in the First Amendment. The guarding of military and diplomatic secrets at the expense of informed representative government provides no real security ….

1960s, Farewell address (1961)
Context: Now this conjunction of an immense military establishment and a large arms industry is new in the American experience. The total influence — economic, political, even spiritual — is felt in every city, every Statehouse, every office of the Federal government. We recognize the imperative need for this development. Yet we must not fail to comprehend its grave implications. Our toil, resources, and livelihood are all involved. So is the very structure of our society.
In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.

2011, Address on interventions in Libya (March 2011)
Context: As the bulk of our military effort ratchets down, what we can do — and will do — is support the aspirations of the Libyan people. We have intervened to stop a massacre, and we will work with our allies and partners to maintain the safety of civilians. We will deny the regime arms, cut off its supplies of cash, assist the opposition, and work with other nations to hasten the day when Qaddafi leaves power. It may not happen overnight, as a badly weakened Qaddafi tries desperately to hang on to power. But it should be clear to those around Qaddafi, and to every Libyan, that history is not on Qaddafi’s side. With the time and space that we have provided for the Libyan people, they will be able to determine their own destiny, and that is how it should be.
