US Presidency
1961

And it is in the light of that history that every nation today should know, be he friend or foe, that the United States has both the will and the weapons to join free men in standing up to their responsibilities. But I come here today to look across this world of threats to a world of peace. In that search we can not expect any final triumph for new problems will always arise. We can not expect that all nations will adopt like systems -for conformity is the jailer of freedom, and the enemy of growth. Nor can we expect to reach our goal by contrivance, by fiat or even by the wishes of all. But however close we sometimes seem to that dark and final abyss, let no man of peace and freedom despair. For he does not stand alone.
