AP World History: Modern Unit 8 practice questions

• WWII ends. Europe is in ruins. Two nations emerge with overwhelming military and industrial power — and they HATE each other's ideology. One is capitalist and democratic. The other is communist and authoritarian. Who are they?

  The United States and the Soviet Union. Both won WWII but represented opposing systems: U.S. = democratic capitalism. USSR = authoritarian communism. Their rivalry — ideological, military, economic — defined the second half of the 20th century.

• After WWI, colonized peoples hoped loyalty would earn them freedom. It didn't. After WWII, everything is different — European empires are broke, bombed, and morally bankrupt. THIS time, colonial peoples can't be denied. What changed?

  WWII devastated European powers economically, militarily, and morally. It exposed the hypocrisy of fighting for 'freedom' while maintaining colonies. Japan's conquests proved Europeans COULD be defeated. And power shifted to the U.S. and USSR — neither initially supporting traditional European colonialism.

• The U.S. and USSR both have nuclear weapons. Direct war between them would destroy the planet. So how do you fight your rival without triggering nuclear annihilation? You fight EVERYWHERE ELSE — through other people's wars. What makes the Cold War 'cold'?

  No direct superpower combat — nukes made it suicidal. They fought instead through proxy wars, arms and space races, propaganda, and espionage — cold between them, hot everywhere else.

• The Cold War says: choose a side. Capitalism or communism. U.S. or USSR. But a group of newly independent nations says: 'Neither. We're not YOUR pawns.' They form their own bloc. What's it called, and who leads it?

  The Non-Aligned Movement — led by Sukarno and Nkrumah. These nations refused to ally with either superpower, seeking sovereignty and development without becoming Cold War pawns.

• NATO vs. Warsaw Pact. Nuclear arms race. And proxy wars — Korea, Angola, Nicaragua — where the superpowers back opposite sides and let SOMEONE ELSE'S country get destroyed. Who pays the highest price in the Cold War?

  The developing world bore the proxy-war devastation. Korea, Vietnam, Angola, and Nicaragua became battlefields for a rivalry whose smaller nations had no say in.

• Communist North Korea (backed by USSR/China) invades non-communist South Korea (backed by U.S./UN) in 1950. Three years of devastating war. No clear winner. Korea STILL divided today. What does this war establish about Cold War dynamics?

  The template for Cold War proxy wars on someone else's soil. Korea set the pattern repeated in Vietnam, Angola, and Nicaragua: superpowers compete, the smaller nation bleeds.

• China endured the Opium Wars (Unit 6), the Qing collapse (Unit 7), Japanese invasion, and a corrupt Nationalist government. By 1949, millions of desperate peasants follow a communist leader who promises land reform and national dignity. Who is he?

  Mao Zedong, whose communists won after a century of pain. Opium Wars, Qing collapse, warlords, and Japanese invasion each fed the next; communism promised restored dignity.

• Mao launches the Great Leap Forward: collectivize farms, build backyard steel furnaces, industrialize China in five years. Sound familiar? Stalin tried the SAME thing with Five-Year Plans. Mao gets the SAME result. What is it?

  Catastrophe — history's worst famine killed millions. Forced collectivization wrecked farming and backyard furnaces made useless steel — the same disaster as Stalin's plans.
