“The strongest bond of human sympathy, outside of the family relation, should be one uniting all working people, of all nations, and tongues, and kindreds.”

in Indonesia, Palestine, and Kashmir - has demonstrated convincingly that parties to the most severe conflict may be induced to abandon war as the method of settlement in favour of mediation and conciliation, at a merciful saving of untold lives and acute suffering. Unfortunately, there may yet be some in the world who have not learned that today war can settle nothing, that aggressive force can never be enough, nor will it be tolerated. If this should be so, the pitiless wrath of the organized world must fall upon those who would endanger the peace for selfish ends. For in this advanced day, there is no excuse, no justification, for nations resorting to force except to repel armed attack.
Some Reflections on Peace in Our Time (1950)

As a matter of selfish policy, leaving right and humanity out of the question, we cannot wisely pursue any other course. Other governments mainly depend for security upon the sword; ours depends mainly upon the friendship of the people. In all matters, in time of peace, in time of war, and at all times, it makes its appeal to the people, and to all classes of the people. Its strength lies in their friendship and cheerful support in every time of need, and that policy is a mad one which would reduce the number of its friends by excluding those who would come, or by alienating those who are already here.

2015, Address to the People of India (January 2015)
Context: Our nations are strongest when we uphold the equality of all our people -- and that includes our women. Now, you may have noticed, I’m married to a very strong and talented woman. Michelle is not afraid to speak her mind, or tell me when I’m wrong -- which happens frequently. And we have two beautiful daughters, so I’m surrounded by smart, strong women. And in raising our girls, we’ve tried to instill in them basic values -- a sense of compassion for others, and respect for themselves, and the confidence that they can go as far as their imaginations and abilities will carry them. [... ] We know from experience that nations are more successful when their women are successful. When girls go to school -- this is one of the most direct measures of whether a nation is going to develop effectively is how it treats its women. When a girl goes to school, it doesn’t just open up her young mind, it benefits all of us -- because maybe someday she’ll start her own business, or invent a new technology, or cure a disease. And when women are able to work, families are healthier, and communities are wealthier, and entire countries are more prosperous. And when young women are educated, then their children are going to be well educated and have more opportunity. So if nations really want to succeed in today’s global economy, they can’t simply ignore the talents of half their people. And as husbands and fathers and brothers, we have to step up -- because every girl’s life matters. Every daughter deserves the same chance as our sons. Every woman should be able to go about her day -- to walk the streets or ride the bus -- and be safe, and be treated with respect and dignity. She deserves that.

1920s, Toleration and Liberalism (1925)
Context: In a conflict which engaged all the major nations of the earth and lasted for a period exceeding four years, there could be no expectation of material gains. War in its very essence means destruction. Never before were contending peoples so well equipped with every kind of infernal engine calculated to spread desolation on land and over the face of the deep. Our country is only but now righting itself and beginning a moderate but steady recovery from the great economic loss which it sustained. That tremendous debt must be liquidated through the laborious toil of our people. Modern warfare becomes more and more to mean utter loss, destruction, and desolation of the best that there is of any people, its valiant youth and its accumulated treasure. If our country secured any benefit, if it met with any gain, it must have been in moral and spiritual values. It must be not because it made its fortune but because it found its soul. Others may disagree with me, but in spite of some incidental and trifling difficulties it is my firm opinion that America has come out of the war with a stronger determination to live by the rule of righteousness and pursue the course of truth and justice in both our domestic and foreign relations. No one can deny that we have protected the rights of our citizens, laid a firmer foundation for our institutions of liberty, and made our contribution to the cause of civilization and humanity. In doing all this we found that, though of many different nationalities, our people had a spiritual bond. They were all Americans.

2016, Convention (August 2016)
Context: We’re one team. One American family. When any member of our family is suffering, we’ve got to be there for each other.... We have to keep on uniting as one team. As one people. As one nation.

Context: Can it be possible that all human sympathies can thrive, and all human powers be exercised, and all human joys increase, if we live with all our might with the thirty or forty people next to us, telegraphing kindly to all other people, to be sure? Can it be possible that our passion for large cities, and large parties, and large theatres, and large churches, develops no faith nor hope nor love which would not find aliment and exercise in a little "world of our own"?
