The Grand Alliance was a strange partnership because the Western nations had little in common with the Soviet Union beyond the necessity to defeat their enemies, and many Soviet wartime aims conflicted with those of its allies. Woodrow Wilson contributed to United States (US) distrust of the Soviet Union with his anti-Bolshevik rhetoric during the fight over the League of Nations and his toleration of witch-hunting subordinates, both of which helped create the "Red Scare." His nonrecognition policy was continued by Republican presidents, who periodically issued condemnations of Soviet activities within Russia and abroad. Soviet-US collaboration during the war would make the American people more receptive to playing an active part in world affairs during peacetime. The Soviets were disappointed again by the Casablanca Conference of January 1943. Franklin Delano Roosevelt's success in trying to resolve the contradictions between idealistic wartime statements and his realistic assessment of Soviet goals depended on Stalin's cooperation in Eastern Europe.
