Among the factors that led to World War II was Group of answer choices the aggressive foreign policy of the United States following World War I. the inability of the Soviet Union to oppose Germany. the inability of Britain and France to agree on the terms of the Versailles treaty. the failure of efforts of collective security such as the League of Nations and treaties.

Although there were many causes of World War II, much of the blame is traced to the failure of the Treaty of Versailles at the end of World War I. During the 1920's and 1930's, totalitarian states had established control under: Nazi leader Adolf Hitler in Germany; fascist leader Benito Mussolini in Italy; communist leader Joseph Stalin in the Soviet Union, and Emperor Hirohito in Japan. The inability of the League of Nations to deal with the aggressive acts of these nations, combined with the isolationism of the U.S., and the appeasement of Adolf Hitler eventually led to World War II. In the years following the rise of dictators in Europe, an ethnic cleansing of undesirables was carried out in Hitler's Final Solution.

this means that germany had to pay the allied countries. reparations are/is essentially payment for something that they have done wrong, so after ww1, germany was forced to pay reparations so they could replenish the allied countries resources' that they had lost during the war.
