Apr 15, 2025

Vietnam War Lecture Notes

Introduction

  • Focus on U.S. involvement in the Cold War, specifically the Vietnam War.
  • Explaining causes and effects of the Vietnam War.

Background

  • Geographic Reality: Vietnam divided into North (communist, Ho Chi Minh) and South (democratic, allied with U.S.) after decolonization.
  • Political Context: North Vietnam was under communist governance, while South Vietnam had strong ties to the U.S.

U.S. Involvement

  • Eisenhower's Domino Theory: Suggested that if South Vietnam fell to communism, neighboring countries would follow.
  • Kennedy's Approach:
    • Supported the domino theory.
    • Sent 16,000 military "advisers" to South Vietnam to support, not fight.

Escalation under Lyndon B. Johnson

  • Gulf of Tonkin Incident: North Vietnamese allegedly fired on a U.S. battleship.
    • Led to the Gulf of Tonkin Resolution, giving Johnson the power to escalate U.S. military involvement without a formal declaration of war by Congress.
    • Sparked debate over the executive branch's military actions without congressional approval.
  • Military Escalation:
    • U.S. troops increased significantly (200,000 by 1965, doubling by 1967).
    • North Vietnamese proved more resilient than expected.

Domestic Impact and Credibility Gap

  • The Vietnam War was the first truly televised war, revealing the harsh realities of the conflict.
  • Credibility Gap: Discrepancy between the Johnson administration's positive reports and the grim reality shown on TV.
  • Domestic opposition grew with anti-war protests alongside the civil rights movement.

The Tet Offensive

  • A significant surprise attack by the North Vietnamese, causing heavy U.S. casualties.
  • Despite a U.S. counterattack, the offensive led to Johnson stopping further escalation.

Transition to Nixon and Vietnamization

  • Richard Nixon:
    • Sought to reduce U.S. involvement without admitting defeat.
    • Proposed "Vietnamization," withdrawing U.S. troops while continuing financial and military support to South Vietnam.

Conclusion

  • Nixon effectively ended U.S. involvement in the Vietnam War.
  • Importance of understanding the Vietnam War in the broader context of U.S. foreign policy during the Cold War.
