13.2 The Cold War: Domestic Politics & the Collapse of the U.S.S.R.

Key Takeaways

  • Lyndon B. Johnson's Great Society (1964–1965) created Medicare and Medicaid and launched the War on Poverty, all while the escalating Vietnam War strained the federal budget and public support.
  • The Watergate scandal — a 1972 break-in at Democratic National Committee headquarters and its cover-up — forced Richard Nixon to resign on August 9, 1974, the only U.S. president ever to do so.
  • Nixon pursued détente alongside Watergate: his 1972 opening to China and the SALT I treaty with the U.S.S.R. eased Cold War tensions even as domestic politics grew more turbulent.
  • Mikhail Gorbachev's glasnost (political openness) and perestroika (economic restructuring), begun in 1985, loosened Soviet control and allowed Eastern Europe's 1989 revolutions and the fall of the Berlin Wall.
  • The Cold War ended when the U.S.S.R. formally dissolved on December 25, 1991, splitting into 15 independent republics, including Russia and Ukraine.

Why This Topic Matters on the GED

This section covers a run of names the official content outline groups directly under "The Cold War" — Lyndon B. Johnson's Great Society, Richard Nixon's Watergate scandal, and the collapse of the U.S.S.R. — even though the first two are usually taught as domestic political history. That grouping is intentional and testable: all three events happened while the Cold War was the dominant backdrop of American politics, and each shaped how the Cold War itself eventually ended. Expect GED items to connect a domestic event (like Watergate) to a foreign-policy consequence (like the War Powers Resolution reasserting Congress's check on presidential war-making) — a classic cause-and-effect pattern this test rewards.

LBJ's Great Society: Reform Under Cold War Pressure

After winning a landslide election in 1964, President Lyndon B. Johnson launched The Great Society, a sweeping set of domestic programs aimed at eliminating poverty and racial injustice. Its signature achievements include:

  • War on Poverty — launched via the Economic Opportunity Act (1964), creating programs like Head Start and Job Corps.
  • Medicare (1965) — federal health insurance for Americans 65 and older.
  • Medicaid (1965) — federal-state health insurance for low-income Americans.
  • Elementary and Secondary Education Act (1965) — the first major federal funding for K–12 public schools.
  • Immigration and Nationality Act (1965) — abolished the discriminatory national-origins quota system that had governed U.S. immigration since the 1920s.

The catch: Johnson pursued all of this while dramatically escalating U.S. involvement in the Vietnam War, a Cold War proxy conflict against communist North Vietnam. The tension between funding ambitious domestic reforms ("butter") and an expensive, increasingly unpopular war ("guns") became known as the guns-and-butter dilemma, and it grew so politically damaging that Johnson declined to run for re-election in 1968.

Nixon: Détente Abroad, Watergate at Home

Richard Nixon, elected in 1968, pursued a paradoxical legacy: genuine Cold War breakthroughs alongside the most damaging domestic political scandal in modern U.S. history.

Foreign Policy Achievements: Détente

Détente — an easing of Cold War tensions — defined Nixon's approach to both major communist powers:

  • 1972 visit to China — Nixon became the first U.S. president to visit the People's Republic of China, opening diplomatic relations after 23 years of official non-recognition.
  • SALT I (1972) — the Strategic Arms Limitation Talks produced a treaty with the U.S.S.R. limiting each side's anti-ballistic missile systems and freezing the number of intercontinental ballistic missiles, the first major U.S.-Soviet arms-control agreement.

The Watergate Scandal

In June 1972, operatives connected to Nixon's re-election campaign broke into the Democratic National Committee's headquarters at the Watergate office complex in Washington, D.C., to plant wiretaps. Nixon was not shown to have ordered the break-in itself, but recorded White House tapes later proved he directed a cover-up of the investigation — obstructing justice. As the scandal unraveled through congressional hearings and the "smoking gun" tape, the House Judiciary Committee approved articles of impeachment. Facing near-certain impeachment and removal, Nixon resigned on August 9, 1974 — the only U.S. president ever to resign from office. Vice President Gerald Ford succeeded him and later issued Nixon a full pardon.

Watergate had a lasting civics consequence directly tied to Cold War foreign policy: Congress passed the War Powers Resolution (1973) over Nixon's veto, requiring the president to notify Congress within 48 hours of committing troops abroad and limiting deployments to 60 days without congressional authorization — a direct response to executive overreach in Vietnam.

The Collapse of the U.S.S.R.

The Cold War's final act unfolded over roughly a decade of mounting Soviet economic and political strain:

StepYear(s)What Happened
Renewed U.S. pressureearly 1980sPresident Reagan built up U.S. military spending and called the U.S.S.R. an "evil empire," straining the Soviet economy's ability to keep pace
Gorbachev's reforms1985 onwardMikhail Gorbachev became Soviet leader and introduced glasnost and perestroika
Eastern European revolutions1989Poland's Solidarity movement won free elections; Czechoslovakia's Velvet Revolution and other uprisings toppled communist governments across the Eastern Bloc
Fall of the Berlin WallNovember 9, 1989East Germans crossed freely into West Berlin for the first time since 1961, symbolizing the collapse of Soviet control over Eastern Europe
German reunificationOctober 1990East and West Germany formally reunited as one nation
Dissolution of the U.S.S.R.December 25, 1991The Soviet Union formally dissolved into 15 independent republics, including Russia and Ukraine, ending the Cold War

Glasnost vs. Perestroika

GED questions frequently test whether you can tell these two Gorbachev-era terms apart:

TermMeaningEffect
Glasnost"Openness" — reduced censorship, more political and press freedomAllowed public criticism of the Soviet government for the first time in decades
Perestroika"Restructuring" — reform of the centrally planned Soviet economyIntroduced limited market mechanisms, exposing how inefficient the planned economy had become

Common Trap

Do not credit Reagan alone or Gorbachev alone for the U.S.S.R.'s collapse. The GED's own content framing treats it as the outcome of sustained external pressure and internal Soviet reform — a passage describing either factor in isolation is describing only part of the cause.

Exam Scenario

A timeline-based item lists "Fall of the Berlin Wall," "Gorbachev introduces glasnost," and "Dissolution of the U.S.S.R." out of order and asks you to place them chronologically. The correct sequence is glasnost (1985) → fall of the Berlin Wall (1989) → dissolution of the U.S.S.R. (1991) — Gorbachev's reforms came first and made the later events possible, not the reverse.
