VIETNAM WAR

The origin of the US in Vietnam

I. The First Indochina War and Containment (Pre-1954)

* Containment Policy & NSC-68: Driven by the belief that all communist activity was directed by Moscow, the U.S. implemented a containment policy to stop the spread of communism [1].

* The Domino Theory: This was the belief that if Vietnam fell to communism, neighboring states in Southeast Asia would inevitably follow [1].

* Support for France: Because of these fears, the U.S. began funding the French military effort in Vietnam after 1950, eventually paying for almost the entire French combat cost [1].

* French Defeat: Despite U.S. aid, the French were defeated at Dien Bien Phu in the spring of 1954 [1].

II. The Geneva Accords and the Rise of Diem (1954–1956)

* Geneva Accords (1954): Officially ended the war; granted independence to Laos, Cambodia, and Vietnam. Vietnam was temporarily divided at the 17th parallel (Ho Chi Minh in the North; Ngo Dinh Diem in the South) [2].

* Migration: Following the accords, over one million anti-communist Vietnamese (many Roman Catholic) fled from the North to the South [2].

* Leadership Challenges: Diem, a Catholic leader in a predominantly Buddhist nation, struggled to establish a stable government and ruled harshly [2].

* Cancelled Elections: Diem, supported by the U.S., rejected the 1956 unifying elections mandated by the Geneva Accords, fearing he would lose to Ho Chi Minh [3].

III. The Civil War Phase (1957–1960)

* The Viet Cong (VC): These were old Viet Minh fighters and communists living in South Vietnam who began striking against Diem’s government [3].

* ARVN Actions: Diem used the Army of the Republic of Vietnam (ARVN) to attack VC fighters starting in 1957, marking the start of the "civil war phase" [4].

* Guerrilla Tactics: The VC used political assassinations and guerrilla warfare, leading to tens of thousands of deaths among civilians and political leaders [4].

* Diem’s Repression: In response, Diem became increasingly aggressive and repressive against any areas suspected of supporting the VC [4].

IV. Kennedy and Strategic Escalation (1961–1963)

* The Ho Chi Minh Trail: Supplies from the North reached the VC via a network of trails through Laos and Cambodia [5].

* Military Advisors: President Kennedy significantly increased the number of U.S. military advisors from a few hundred in the late 1950s to over 11,000 by 1962 and 16,000 by late 1963 [5, 6].

* The Buddhist Crisis: Diem’s harsh treatment of Buddhists led to international outrage, highlighted by the self-immolation of Buddhist monks [5, 7].

* The 1963 Coup: Recognizing Diem could not unify the country, the U.S. sanctioned an ARVN military coup in November 1963, which resulted in Diem’s execution [7].

V. Johnson and the Gulf of Tonkin (1963–1964)

* LBJ’s Dilemma: After Kennedy’s assassination, Lyndon B. Johnson (LBJ) feared that "losing" Vietnam would make him look "soft on communism" and jeopardize his Great Society domestic programs [6, 8].

* Gulf of Tonkin Incident (August 1964):

The *USS Maddox** was reportedly fired upon by North Vietnamese gunboats on August 2nd; a second reported attack on August 4th was later doubted by intelligence [8, 9].

* U.S. Response: LBJ ordered retaliatory airstrikes against North Vietnamese naval bases [9].

* Gulf of Tonkin Resolution: Passed by Congress on August 7, 1964, it gave LBJ "carte blanche" (full authority) to take any necessary measures to defend U.S. forces and South Vietnam [9].

* Shift to Full Combat: This resolution allowed the U.S. to move from thousands of advisors to hundreds of thousands of combat troops, pulling the U.S. deep into the conflict [9].

Johnson years of the Vietnam War (1964–1968)

Inheritance and the Legal Basis for War

* Succession: Lyndon B. Johnson (LBJ) assumed the presidency after John F. Kennedy's assassination in a period of extreme instability for South Vietnam [1].

* South Vietnamese Instability: The government was in turmoil following the coup against Ngo Dinh Diem, leading to repeated subsequent coups [1].

* Communist Gains: The Viet Cong (VC) were expanding control in rural areas, supported by supplies flooding in via the Ho Chi Minh Trail [1].

* Gulf of Tonkin Resolution: This resolution provided the legal basis LBJ sought to escalate American involvement in the conflict [1].

Operation Rolling Thunder (1965–1968)

* Strategy: A major strategic bombing campaign against North Vietnam lasting three years [1].

* Scale: The U.S. dropped more bombs on North Vietnam than were used in the entire European theater of World War II [1, 2].

* Objectives: To boost South Vietnamese morale, weaken the North's ability to support fighters in the South, and force the North to negotiate [2].

* LBJ’s Restrictions: Fearing further escalation, Johnson refused "unrestricted bombing," protecting civilian centers like Hanoi from the full force of the air force [2].

* Failure of the Campaign:

* It failed to bring the North to the table; the North refused to talk until bombing stopped, while the U.S. refused to stop until infiltration ceased [3].

Strategic bombing was ineffective against an *unindustrialized state** like North Vietnam, which received its materials from China and the USSR [3].

Over *700 American jets** were shot down by Soviet-supplied air defenses, leading to hundreds of U.S. pilots becoming prisoners of war (POWs) [4].

Ground War and Escalation

* Troop Injection: In March 1965, the first combat Marines were sent to defend air bases, initially under a limited "exclave strategy" [4].

* Americanization: The U.S. quickly took over the "heavier load" of the war from the South Vietnamese army (ARVN) [5].

* Rapid Growth: Troop levels surged from approximately 100,000 in early 1965 to over 500,000 by the end of 1968 [5].

* War of Attrition: Success was measured by body counts rather than territory gained [5, 6].

* Unreliability: Body counts were often inaccurate or inflated; as one veteran noted, "if it was dead and Vietnamese, it was Viet Cong" [6].

* Miscalculation: The U.S. underestimated the North's willingness to endure massive human losses to achieve their goals [6].

Tactics and the Human/Environmental Cost

* Search and Destroy: Missions aimed to hunt and eliminate communist base camps in rural areas [6].

* **Chemical Warfare:** Agent Orange (a defoliant) was used to clear the jungle. It was later discovered to be a carcinogen, causing high rates of cancer and birth defects for both veterans and Vietnamese civilians [7].

* Guerrilla Mobility: Despite U.S. helicopter mobility, the VC had superior ground knowledge and used an intricate tunnel system for movement [6, 7].

* Refugee Crisis: Extensive bombing and fighting in the South disrupted agriculture and killed civilians, forcing rural populations into urban centers [8].

The Turning Point: The Tet Offensive (January 1968)

* The Attack: A coordinated strike by communist forces on dozens of U.S. and South Vietnamese cities and bases during the Tet holiday [8].

* Communist Goals: To trigger a popular uprising in the South, disrupt the government, and force U.S. withdrawal [9].

* Military Outcome: A military failure for the communists; they suffered 30,000 deaths (out of 80,000), failed to spark an uprising, and were driven out of all territory within days [9, 10].

* Political Outcome (The "Credibility Gap"):

* Tet shattered the public's trust in the government's claim that there was "light at the end of the tunnel" [10].

LBJ *refused General Westmoreland’s request** for more troops, effectively ending the pattern of escalation [10, 11].

Influential media figures, like *Walter Cronkite**, began declaring the war "unwinnable," leading to increased pressure for a negotiated peace [11].
