11. Woodrow Wilson - Need for the League
Debate in Congress
Woodrow Wilson - Need for the League
America is going to grow more and more powerful, and the more powerful she is the more inevitable it is that she should be trustee for the peace of the world…All Europe knew that we were doing an American thing when we put the Covenant of the League of Nations at the beginning of the treaty…The most cynical men I had to deal with…before our conferences were over all admitted that the League of Nations, which they had deemed an ideal dream, was a demonstrable, practical necessity. This treaty cannot be carried out without the League of Nations… The rest of the world is necessary to us, if you want to put it on that basis. I do not like to put it on that basis. That is not the American basis. America does not want to feed upon the rest of the world. She wants to feed it and serve it. America…is the only national idealistic force in the world and idealism is going to save the world…That is the program of civilization.” Woodrow Wilson, Speech at Helena, Montana, September 1919

12. Henry Cabot Lodge - Danger of the League
Debate over the League
Henry Cabot Lodge - Danger of the League
Never forget that this league is primarily – I might say overwhelmingly – a political organization, and I object strongly to having the politics of the United States turn upon disputes where deep feeling is aroused but in which we have no direct interest. It will tend to delay the Americanization of our great population, and it is more important not only to the United States but to the peace of the world to make all these people good Americans than it is to determine that some piece of territory should belong to one European country rather than to another. For this reason I wish to limit strictly our interference in the affairs of Europe and of Africa. We have interests of our own in Asia and in the Pacific which we must guard upon our own account, but the less we undertake to play the part of umpire and thrust ourselves into European conflicts the better for the United States and for the world.”
Speech in the Senate, Aug 1919
