The main American demands at the Moscow conference was to have a new international organization replace the League of Nations to be called the United Nations; to have Soviet Union to agree to adhere to the "unconditional surrender" formula adopted at the Casablanca conference (a major point given that the Soviets sometimes hinted that they were willing to sign a separate peace with Germany); and for the "Big Three" powers whom it was assumed would dominate the post-war world to be a "Big Four" as the Americans wanted China to stand alongside the United States, the Soviet Union, and Great Britain as one of the world's dominant powers.
