In Buenos Aires, President Roosevelt gave a speech to open the Inter-American Conference for the Maintenance of Peace on December 1, 1936. In it, FDR called upon the nations of the New World to unite and help the Old World avert war. The President said this union of American nations should be so constituted that in case of aggression from the Old World, it would stand shoulder to shoulder, wholly prepared to consult together for mutual safety and mutual good.
