In this episode, we trace the long road to America’s deepening involvement in Vietnam and the breaking point it created at home. Beginning with Truman and Eisenhower, we explore how containment, domino theory, and Cold War fears pulled the United States into a conflict that presidents kept expanding. Then we follow the war through Kennedy, Johnson, the Gulf of Tonkin, and the quagmire that followed. Finally, we turn to 1968, when Tet, protest, assassinations, and political backlash shattered public confidence and transformed American politics, exposing the limits of American power abroad and consensus at home in a divided modern nation.
