“America is my home — I believe in her promise and I will do what I can to secure that promise for future generations of our children. America is great — not because of our military might or our economic strength — but because of the greatness of Americans, and I welcome the opportunity to stand shoulder to shoulder, side by side with all of you to preserve our heritage rich in "liberty and justice for all."”

Context: For all Americans. Because I believe we are stronger together. It’s a vision for the future rooted in our values and reflected in a rising generation of young people who are the most open, diverse, and connected we’ve ever seen.... Let’s keep moving forward together. Let’s stand up against prejudice and paranoia. Let’s prove once again, that America is great because is America is good.

1910s, Address to the Knights of Columbus (1915)
Context: All of us, no matter from what land our parents came, no matter in what way we may severally worship our Creator, must stand shoulder to shoulder in a united America for the elimination of race and religious prejudice. We must stand for a reign of equal justice to both big and small. We must insist on the maintenance of the American standard of living. We must stand for an adequate national control which shall secure a better training of our young men in time of peace, both for the work of peace and for the work of war. We must direct every national resource, material and spiritual, to the task not of shirking difficulties, but of training our people to overcome difficulties. Our aim must be, not to make life easy and soft, not to soften soul and body, but to fit us in virile fashion to do a great work for all mankind. This great work can only be done by a mighty democracy, with these qualities of soul, guided by those qualities of mind, which will both make it refuse to do injustice to any other nation, and also enable it to hold its own against aggression by any other nation. In our relations with the outside world, we must abhor wrongdoing, and disdain to commit it, and we must no less disdain the baseness of spirit which lamely submits to wrongdoing. Finally and most important of all, we must strive for the establishment within our own borders of that stern and lofty standard of personal and public neutrality which shall guarantee to each man his rights, and which shall insist in return upon the full performance by each man of his duties both to his neighbor and to the great nation whose flag must symbolize in the future as it has symbolized in the past the highest hopes of all mankind.

In response to the cheer that was raised after he sent the signal "England expects every Man will do his Duty.", as quoted in The Life of Admiral Lord Nelson, K.B. from His Lordship's Manuscripts (1810) by James Stanier Clarke and John McArthur, p. 667
