The Great Society

President Lyndon B. Johnson launched the most ambitious reform program since the New Deal, the Great Society, aiming to end poverty and racial injustice. It created Medicare and Medicaid (health care for the elderly and poor), federal aid to education, immigration reform (the 1965 Immigration Act), and a "War on Poverty." These programs expanded the federal safety net and cut poverty significantly, extending New Deal liberalism to its high-water mark — even as the Vietnam War drained resources and political will from the effort.

The quagmire in Vietnam

Cold War containment drew the U.S. into Vietnam to stop a communist takeover, guided by the "domino theory." After the Gulf of Tonkin Resolution (1964), Johnson escalated to over half a million troops, yet a determined enemy and difficult guerrilla war produced no victory. The Tet Offensive (1968) shattered claims that the war was being won and turned public opinion against it. A growing antiwar movement and a "credibility gap" between government claims and reality tore at national unity.

Nixon, Watergate, and a decade of disillusion

Richard Nixon pursued "Vietnamization" and détente with China and the USSR, but the war dragged on until 1973, ending in eventual communist victory. At home, the Watergate scandal — Nixon’s cover-up of a break-in — forced his resignation in 1974, deepening public distrust of government. Combined with stagflation (simultaneous inflation and unemployment) and the 1973 oil crisis, the 1970s left Americans disillusioned with government and primed for a conservative turn.

Worked example

Briefly explain how the Tet Offensive affected American public opinion about the Vietnam War.

1.Describe the government’s prior message: officials had assured the public the war was being won and the enemy was weakening.
2.State what Tet showed: in early 1968 communist forces launched massive, coordinated attacks across South Vietnam.
3.Explain the effect: even though the attacks were repelled militarily, they contradicted official optimism, widening the "credibility gap" and swinging opinion against the war.

Answer: The Tet Offensive contradicted government assurances that victory was near; although U.S. forces repelled the attacks, the scale of the assault convinced many Americans they had been misled, widening the credibility gap and turning public opinion sharply against the war.
