Peace does not rest in charters and covenants alone. It lies in the hearts and minds of all people. And if it is cast out there, then no act, no pact, no treaty, no organization can hope to preserve it without the support and the wholehearted commitment 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 our people.
— John F. Kennedy
