My friends, our challenge today is not to save Western civilization — or Eastern, for that matter. All civilization is at stake, and we can save it only if all peoples join together in the task. You Americans did so much, in the last century, to build an effective multilateral system, with the United Nations at its heart. Do you need it less today, and does it need you less, than 60 years ago? Surely not. More than ever today, Americans, like the rest of humanity, need a functioning global system through which the world’s peoples can face global challenges together. And in order to function more effectively, the system still cries out for far-sighted American leadership, in the Truman tradition. I hope and pray that the American leaders of today, and tomorrow, will provide it.

Knowledge is power. Information is liberating. Education is the premise of progress, in every society, in every family.

Truman's name will for ever be associated with the memory of far-sighted American leadership in a great global endeavour. And you will see that every one of my five lessons brings me to the conclusion that such leadership is no less sorely needed now than it was 60 years ago.
