AP US History Unit 9 practice questions

• Reagan won in 1980 declaring 'Government IS the problem.' After 50 years of expanding government — New Deal through Great Society — why did Americans suddenly want LESS?

  Trust in government had collapsed, and Reagan's message landed. Vietnam (government lied), Watergate (a criminal president), stagflation (government couldn't fix the economy), and the Iran hostage crisis (government looked helpless) had disillusioned the nation.

• FDR spent government money to stimulate demand (Keynesian). Reagan cut taxes so the wealthy would invest and wealth would 'trickle down' (supply-side). Which actually worked?

  Both had mixed results; neither one clearly outperformed. Reagan's 1981 tax cuts boosted the stock market and GDP, but the federal deficit tripled, inequality widened, and wealth did not trickle down to working families — Reagan was later forced to raise taxes.

• Reagan cut taxes, slashed social programs, and deregulated industries — but massively increased military spending. How do you 'shrink government' and spend more?

  You run enormous deficits — the deficit tripled under Reagan. He cut programs for the poor while expanding defense, revealing that 'small government' conservatism was selective: less government for social programs, more for military.

• Reagan called the USSR an 'evil empire,' proposed a space-based missile shield (Star Wars), and ramped defense spending to $300 billion. Critics said he risked nuclear war. What was the actual strategy?

  Reagan's buildup aimed to bankrupt the USSR with a spending race it couldn't win. SDI was probably unbuildable, but the threat forced the Soviets to try to keep up — and combined with Gorbachev's reforms and internal Soviet decay, the strategy contributed to the USSR's 1991 collapse.

• Reagan demanded Gorbachev tear down the Berlin Wall in 1987. Two years later it came down. Two years after that the Soviet Union dissolved. What actually ended the Cold War?

  Several converging forces ended the Cold War at about the same time. Gorbachev's Perestroika and Glasnost reforms weakened Soviet control, Reagan's military and economic pressure strained the Soviet budget, Eastern Europeans demanded freedom, and the Soviet economy was fundamentally broken.

• Congress banned US aid to Nicaraguan Contras via the Boland Amendment. Reagan's team sold weapons to Iran and funneled the profits to the Contras anyway. What does Iran-Contra reveal?

  Iran-Contra had the White House illegally skirt Congress to arm rebels. It violated the Boland Amendment and Arms Export Control Act, revealing that Cold War zeal could override the law — even under a president who championed the rule of law.

• After the Cold War, George H.W. Bush assembled a 34-nation coalition and expelled Iraq from Kuwait in 100 hours. Why didn't the US finish off Saddam Hussein?

  Bush deliberately left Saddam in power to avoid a destabilizing occupation. He feared regime change would require a long occupation and fracture the coalition. That restraint looked wise — until his son invaded Iraq in 2003 specifically to remove Saddam, creating the exact chaos his father had avoided.

• NAFTA (1994) lowered trade barriers between the US, Canada, and Mexico. Conservatives cheered free markets. Liberals feared job losses. Both were partly right — what actually happened?

  NAFTA raised trade and cut prices but sped US factory job losses. Manufacturing moved to Mexico where labor was cheaper, so Rust Belt workers suffered while corporate profits rose — making NAFTA the symbol of globalization's uneven distribution of gains.
