US Presidency
1870

If ever the United States, they said, permit themselves to be associated with these nations in any general congress assembled for the discussion of common plans in any way affecting European interests, they will by such act not only deprive themselves of the ability they now possess of rendering useful assistance to the other American States, but also produce other effects prejudicial to their own interests. Thus the necessity at that day of preserving the great interest of the Southern States in African slavery, and of preventing a change in the character of labor in the islands of Cuba and Porto Rico, lost to the United States the opportunity of giving a permanent direction to the political and commercial connections of the newly enfranchised Spanish American States, and their trade passed into hands unfriendly to the United States, and has remained there ever since.
