What this topic is asking
Standard VUS.10 asks for the causes of World War II, the rise of totalitarian and fascist dictators, American isolationism in the 1930s, and the events, above all Pearl Harbor, that drew the United States into the war. The exam wants you to connect the harsh peace after World War I and the Depression to the rise of aggressive dictatorships, and to explain how isolationism gave way to war.
The rise of the dictators
The Depression and the bitterness of the World War I peace helped dictators seize power by promising order and national revival:
- Adolf Hitler in Germany (Nazi, fascist), who blamed Jews and others and sought to dominate Europe.
- Benito Mussolini in Italy (fascist).
- Joseph Stalin in the Soviet Union (communist totalitarian).
- Militarists in Japan, who pursued empire in Asia.
Aggression and appeasement
These regimes expanded by force: Japan invaded China, Italy attacked Ethiopia, and Germany rearmed and seized territory in central Europe. The Western democracies tried appeasement, giving in to Hitler's demands (notably at Munich) in hopes of avoiding war. It failed: Hitler kept expanding, and war began when Germany invaded Poland in September 1939.
American isolationism
After the disillusionment of World War I and amid the Depression, the United States turned isolationist, determined to avoid foreign wars and entanglements. Congress passed Neutrality Acts to keep the nation out. But as the Axis threat grew, the United States edged toward the Allies, selling and then lending war materials to Britain through the Lend-Lease program ("the arsenal of democracy") while still not formally at war.
Pearl Harbor and US entry
Pearl Harbor is the decisive event the test asks about: it transformed a reluctant, isolationist nation into a full belligerent overnight.

A single-select item on US entry into World War II (VUS.10).
Correct answer: (B). Japan's surprise attack on the US naval base at Pearl Harbor on December 7, 1941, brought the United States into the war the next day.
A and D belong to World War I; C is the Depression. The test rewards Pearl Harbor as the trigger for US entry into World War II.
VA VUS SOL (released item style)2 marksDictators rose to power in the 1930s as the United States stayed isolationist.
(a) Define totalitarianism. (b) Explain what American isolationism meant before 1941.
Show worked answer →
A two-part constructed response (VUS.10), 2 points (1 per part).
(a) 1 point: totalitarianism is a system in which a dictator or single party controls every aspect of life, with no political freedom (as under Hitler in Germany, Mussolini in Italy, Stalin in the USSR, and the militarists in Japan).
(b) 1 point: isolationism was the policy of avoiding involvement in foreign (especially European) wars and alliances; before 1941 many Americans wanted to stay out of the new war (the Neutrality Acts), though the United States increasingly aided the Allies (Lend-Lease).
Markers reward a definition of totalitarianism and an account of isolationism.
