Which U.S. president said, "No problem of human destiny is beyond human beings"?

The quote here: "No problem of human destiny is beyond human beings" is part of a larger statement. "Our problems are man-made — therefore, they can be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. Man's reason and spirit have often solved the seemingly unsolvable — and we believe they can do it again." This famous statement was passionately made by President John F. Kennedy about four months before he was killed.

On Monday, June 10, 1963, President Kennedy delivered a commencement address at American University. The President's American University speech (as it is now often called) was titled: A Strategy of Peace. This speech and the above quote were then both seen as timely and very insightful by most American citizens.

President Kennedy not only outlined a plan to curb nuclear arms, but he sought to lay out a hopeful, yet realistic route for world peace. This speech was made at a time when the United States and Soviet Union faced the potential for an escalating nuclear arms race.
