President Woodrow Wilson, September 25,1919 in Pueblo, Colorado.  After returning from Paris, President Wilson toured the country to gain support for the treaty and the League. [Modified]

My fellow citizens, as I have crossed the continent, I have perceived more and more that men have been busy creating an absolutely false impression of the treaty of peace and the Covenant of the League of Nations.

Reflect, my fellow citizens that the membership of this great League is going to include all the great fighting nations of the world, as well as the weak ones. And what do they unite for?  They enter into a solemn promise to one another that they will never use their power against one another for aggression; that they never will violate the territorial integrity of a neighbor; that they never will interfere with the political independence of a neighbor; that they will abide by the principle that great populations are entitled to determine their own destiny; and
that no matter what differences arise between them they will never resort to war without first submitting their differences to the consideration of the council of the League of Nations, and agreeing that at the end of the six months, even if they do not accept the advice of the council, they will still not go to war for another three months.


I wish that those who oppose this settlement could feel the moral obligation that rests upon us not to turn our backs on the boys who died, but to see the thing through, to see it through to the end and make good their redemption of the world. For nothing less depends upon this decision, nothing less than liberation and salvation of the world.
