Here are President Kennedy’s comments about founding of the Peace Corps given in his three State of the Union Addresses.

From 1961 State of the Union Address:
“An even more valuable national asset is our reservoir of dedicated men and women — not only on our college campuses but in every age group — who have indicated their desire to contribute their skills, their efforts, and a part of their lives to the fight for world order. We can mobilize this talent through the formation of a National Peace Corps, enlisting the services of all those with the desire and capacity to help foreign lands meet their urgent needs for trained personnel.”

From 1962 State of the Union Address:
“A newly conceived Peace Corps is winning friends and helping people in fourteen countries–supplying trained and dedicated young men and women, to give these new nations a hand in building a society, and a glimpse of the best that is in our country. If there is a problem here, it is that we cannot supply the spontaneous and mounting demand.”

From his last State of the Union Address:
“Finally, the overseas success of our Peace Corps volunteers, most of them young men and women carrying skills and ideas to needy people, suggests the merit of a similar corps serving our own community needs: in mental hospitals, on Indian reservations, in centers for the aged or for young delinquents, in schools for the illiterate or the handicapped. As the idealism of our youth has served world peace, so can it serve the domestic tranquility.

“Neither money nor technical assistance, however, can be our only weapon against poverty. In the end, the crucial effort is one of purpose, requiring the fuel of finance but also a torch of idealism. And nothing carries the spirit of this American idealism more effectively to the far corners of the earth than the American Peace Corps.”
