Vietnam War: Diem’s Rule & Rise of the Vietcong (1954–1963) Flashcards
What methods did Diem use to maintain power from 1955 to 1963?
- Refused to hold 1956 elections (agreed at Geneva) — feared Ho Chi Minh would win.
- Used ARVN and secret police to imprison or kill political opponents — over 12,000 suspected communists arrested.
- Appointed family members to top roles — e.g., brother Ngo Dinh Nhu led brutal secret police.
- Pushed Strategic Hamlet Program (1962): moved peasants to fortified villages to stop Vietcong influence — often backfired.
- Backed by $1.6 billion in US aid between 1955–1961, mainly for military and propaganda.
How did Diem gain power over Emperor Bao Dai in 1955?
- Bao Dai was viewed as a French puppet with little popular support post-independence.
- Diem held a rigged referendum in October 1955 — claimed 98.2% support, even 605,000 votes in Saigon (only 450,000 registered voters).
- With US backing, Diem abolished the monarchy and declared the Republic of Vietnam with himself as president.
- Claimed Bao Dai was corrupt and anti-nationalist — appealed to US anti-communism.
- Established a personalist regime, not a democracy — loyalty to Diem > ideology.
Why did Diem face growing opposition in South Vietnam?
- Strong bias toward Catholics (only ~10% of population) — Buddhists denied jobs, army posts.
- Harsh suppression of protests — including Buddhist monks (e.g. the 1963 Hue Phat Dan incident, 9 killed, Thich Quang Duc). due to Catholics being preferred and Diem had implemented anti-Buddhist policies
- Land reform failed: Diem sided with landlords; peasants remained poor and angry.
- The Strategic Hamlet Program (1962) uprooted villages — turned peasants toward the Vietcong.
- By 1963, thousands of South Vietnamese were secretly supporting or joining the Vietcong.
How did the conflict between North and South Vietnam escalate into civil war?
- In 1959, Ho Chi Minh approved sending weapons and support to anti-Diem fighters in the South.
- The Ho Chi Minh Trail was constructed through Laos and Cambodia — crucial for supplies.
- Vietcong (Southern communists) launched guerrilla attacks on government forces and officials.
- ARVN proved ineffective; US sent 11,000 “advisors” by 1962 to support Diem.
- By 1960, Vietnam was in a de facto civil war, though the US framed it as fighting communism.
What led to the fall and assassination of Diem in 1963?
- Buddhist protests escalated after Hue massacre (May 1963) and self-immolation of Thich Quang Duc (June).
- US media coverage shocked Americans — Diem seen as brutal and unstable.
- Diem’s brother Nhu’s raid on Buddhist pagodas (Aug 1963) alienated even loyalists.
- The US (under JFK) gave a green light to a military coup — Diem and Nhu were executed on Nov 2, 1963.
- Diem’s death led to political instability — 9 governments in 2 years, paving the way for deeper US involvement.
What was the Vietcong and how did it emerge?
- Founded in Dec 1960 as the National Liberation Front (NLF) — mostly southern fighters.
- Aimed to overthrow Diem, reunify Vietnam, and win peasant support.
- Supported by North Vietnam with weapons, leadership, and funding.
- Built strong networks in the countryside — often better organized than the ARVN.
- Appealed to rural poor through promises of land reform and anti-corruption.
Who supported the Vietcong and why?
- Rural peasants, who hated Diem’s rule, saw the Vietcong as the only hope for change.
- Promised fair land distribution, unlike Diem who favoured landlords.
- Used propaganda and community aid to build loyalty — helped with farming and education.
- In some areas, support was coerced — villages punished for refusing.
- Women and children also contributed — e.g., carried supplies, acted as lookouts.-
What tactics did the Vietcong use during the early war years?
- Used guerrilla warfare: surprise attacks, ambushes, sabotage — avoided direct battles.
- Constructed over 250 km of tunnels (e.g., Cu Chi) with living quarters, weapons storage.
- Booby traps like punji sticks, tripwires, and hidden mines caused ~10–15% of US casualties.
- Blended in with civilians — made it hard for US/ARVN to identify enemies.
- Knowledge of terrain gave them a huge advantage — US forces often demoralized.
What were the 1956 elections, and why were they never held?
- The Geneva Agreement (1954) said national elections would be held in July 1956 to reunify Vietnam.
- Ho Chi Minh (North) was expected to win easily — even US intelligence estimated he’d get 80% of the vote.
- Diem (South Vietnam), backed by the USA, refused to hold elections, claiming they wouldn’t be free or fair.
- The US feared a communist victory and supported Diem’s rejection to contain communism (Domino Theory).
- The failure to hold elections made war more likely, as peaceful reunification was blocked.
What was Diem’s “secret mission” in 1956 and what did it reveal?
- Diem sent agents to investigate the strength of communist resistance in rural South Vietnam.
- The mission revealed that Viet Minh networks were still active and gaining local support.
- It warned that US military intervention would not be welcomed by many peasants.
- Highlighted that resistance was political and social, not just military — force alone wouldn’t win.
- Despite this, Diem ignored the findings and increased repression — pushing more people to support the Vietcong.
What were Strategic Hamlets and why were they introduced?
- Introduced in 1962 under Diem’s government with US support.
- Aimed to relocate rural peasants into fortified villages, protected by fences, guards, and watchtowers.
Purpose: - isolate villagers from Vietcong influence, and stop them giving food or shelter to guerrillas.
- Each hamlet was meant to be self-sufficient, with schools and medical care to win “hearts and minds”.
- Over 4,000 hamlets were built by the end of 1963, covering millions of people.
- 2/3 of rural population in hamlets
Why was the Strategic Hamlet Program unsuccessful?
- Forced relocation: Peasants were moved from ancestral homes against their will.
- Promised services (schools, protection) were rarely delivered, causing resentment.
Corruption: - Officials often stole money and supplies, worsening living conditions.
- Vietcong easily infiltrated the hamlets anyway — many peasants still supported them.
- By late 1963, the program collapsed — it increased support for the Vietcong instead of reducing it.
How did the failure of Strategic Hamlets increase pressure on JFK?
- It proved that Diem’s government was unpopular and ineffective, especially in rural areas.
- Despite US financial and military aid, the program backfired — more villagers supported the Vietcong.
- US officials realized that the “hearts and minds” strategy had failed — Diem couldn’t win over his own people.
- By 1963, the US had sent over 16,000 military advisors — but things were getting worse, not better.
- JFK was under growing pressure at home and abroad to either intervene more forcefully or rethink support for Diem, leading to the US-backed coup in November 1963.
