We have tremendous problems abroad--no question about that--a war in Vietnam and threats of war in other areas. We have tremendous problems at home--the crisis of our cities, environmental and others. But on the other hand, look at it in terms as young people should look at the problems--not in terms of the threat, but in terms of the opportunity. Never has this Nation, any nation, had more of an opportunity to do something about its problems, the productivity of our farms, of our factories, and the rest. It is all there if we can only bring it together and get it properly distributed. Also, have this in mind: Have in mind the fact that because you were born in the United States of America and because you live in the United States of America, you in this Nation can play a great role in the affairs of the world--a greater role, actually, than any people in any nation of the world. This is not to downgrade any other great people in the world, because greatness does not come simply from the size of a nation and from the accident of where we happen to be born. But it just does happen that because of the great waves of history that at this time and place the decisions made in the United States of America, as far as the free world is concerned, will determine whether peace and freedom survive in the world. That is the challenge of young America, looking down to the end of this century. It is an exciting challenge, not a burden to be carried and whimpered about, but one to be accepted with all of the excitement that we have when we meet any kind of new experience, any kind of a challenge.
