Motivation for Involvement

  • US convinced China and USSR planning to spread communism in Asia
  • Believed that if Vietnam fell under control of China and USSR other countries would also fall under communism row of dominoes

Foreign Policy: Adopted Policy of Containment:

  • prevent spread of communism worldwide
  • even supported anti communist regimes like Diems despite authoritarianism
  • same approach used by US to resist communism many states Central and South America

John F. Kennedy’s Approach (1961-1963)

  • became US Pres in 1961 replacing Eisenhower
  • possibility of communist victory in Vietnam remained

  • if that happened could result in SEA being lost to communists suggested by domino theory

  • Kennedy cautious but did not want to warn US to in his own words “blunder into war, unclear about aims or how to get out again”

  • military advisors sent out train SV army

  • military equipment continued to be supplied

  • efforts of US organised under military assistance command Vietnam (MACV)

Escalation under Lyndon B. Johnson (1963-1964

  • 1963 Kennedy assassinated succeeded by Lyndon B. Johnson
  • he faced same challenge: avoid full US military committment to Vietnam while pursuing containment policy to prevent communists from coming to power
  • However Johnson more convinced + prepared than Kennedy to commit to US to full scale conflict in Vietnam to contain communism.

Johnsons actions influenced by following:

  • heightened political instability in SV following Diem’s assassination by SV military commanders in 1963 + lack of a strong leader as replacement seemed to favour communist takeover

  • increased tensions between US and communist bloc due to various international developments such as:

    • China exploding its 1st atomic bomb in oct 1964
    • USSR showing little interest in peaceful co-existence with West

committed to preserving independence of SV as anti communist state.

  • US increased number of military advisors and economic assistance
