The document summarizes the political and military buildup to World War 2 in Europe and Asia between the 1920s-1930s. It describes the rise of fascist and totalitarian regimes in Germany under Hitler, Italy under Mussolini, and the Soviet Union under Stalin. It then details Germany and Italy's increasing military aggression and expansionism in violation of postwar treaties, including Germany reoccupying the Rhineland, annexing Austria, and seizing the Sudetenland, along with Italy conquering Ethiopia. Japan also invaded Manchuria in 1931 and began a full-scale war with China in 1937. The appeasement policies of Western democracies failed to stop further aggression, paving the way for WWII.
