John F. Kennedy

But peace does not rest in the charters and covenants alone. It lies in the hearts and minds of all people. So let us not rest all our hopes on parchment and on paper, let us strive to build peace, a desire for peace, a willingness to work for peace in the hearts and minds of all of our people. I believe that we can. I believe the problems of human destiny are not beyond the reach of human beings.
