New Problems in the 1930s Economic Problems in Europe-- As the U.S. struggled to recover during the Great Depression, so did all of Europe. ◦Benito Mussolini rose to power in the 1920s out of an appeal to Italian nationalism. He symbolized the rising force of fascism. ◦Adolph Hitler gained control of Germany in 1933 with calls of anticommunism, anti-Semitism, and the promise to unite all Germans. ◦Japan withdrew from the League of Nations in 1933 in order to create its own empire. The rise of fascism and militarism in Europe and Asia brought the world to war. How is fascism different than Communism?

Appeasement The U.S. followed a policy of cash-and-carry so that they would not get involved. In 1937, Germany, Japan, and Italy signed the Anti-Comintern (Tripartite) Pact and became known as the Axis powers. ◦In 1938, Germany took over Austria, and threatened to annex the Sudetenland (full of ethnic Germans). Munich Conference (1938) ◦British Prime Minister Neville Chamberlain flew to meet with Germany and agreed if that was his last territorial gain. ◦Six months later Hitler took the rest of Czechoslovakia. ◦Is appeasement good foreign policy? Why or why not?

Hitler’s Invasion By 1939 Hitler made little secret that he intended to recapture territory Germany lost to Poland after World War I. Germany and the Soviet Union signed a nonaggression pact in 1939 that would allow Hitler to invade western Poland and Stalin would annex eastern Poland, the Baltic states, and parts of Romania and Finland. Hitler invaded Poland on September 1, 1939 and began an expansion that would eventually lead to all of continental Europe falling into his hands (blitzkreig) However, after Hitler invaded Poland, very little happened. Many began referring to WWII as the “phoney war”, the Bore War or the Sitzkreig.

Would you have been an isolationist or an interventionist. Why?
