“…'world peace' imposed by a dominant power assisted by a few partners is unlikely… only world peace driven by a recognition of the threat to everyone's survival is the most likely source of salvation…”

Interview with David Brancaccio (2003)
Context: We are the dominant power. And that imposes on us a responsibility to be actually concerned with the well being of the world. Because we set the agenda. And there are a lot of problems, including terrorism and weapons of mass destruction, that can only be tackled by collective action. And we ought to be leading that collective action, instead of riding roughshod over other people's opinions and interests.

Address to the Senate (22 January 1917)
1910s
Context: The question upon which the whole future peace and policy of the world depends is this: Is the present war a struggle for a just and secure peace, or only for a new balance of power? If it be only a struggle for a new balance of power, who will guarantee, who can guarantee, the stable equilibrium of the new arrangement? Only a tranquil Europe can be a stable Europe. There must be, not a balance of power, but a community of power; not organized rivalries, but an organized common peace.

for new problems will always arise. We cannot expect that all nations will adopt like systems — for conformity is the jailor 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. If we all can persevere, if we can in every land and office look beyond our own shores and ambitions, then surely the age will dawn in which the strong are just and the weak secure and the peace preserved.
