- 1
What was the Gulf of Tonkin Resolution?
Model answer
Congress voted in August 1964, after reported attacks on American destroyers, to authorise the president to take all necessary measures in south-east Asia, and Johnson treated the resolution as the equivalent of a declaration of war.
- 2
How far did American involvement grow between 1964 and 1968?
Model answer
American strength in Vietnam rose from about 23,000 advisers to more than half a million troops, alongside a sustained bombing campaign against the North.
- 3
What was the credibility gap?
Model answer
The credibility gap was the widening distance between official claims of progress and what Americans saw reported from Vietnam, and it destroyed trust in presidential statements.
- 4
Why was the Tet Offensive a turning point at home?
Model answer
Although the attacks of early 1968 were beaten off, they showed that the enemy could strike everywhere at once, and American opinion concluded that the war could not be won as promised.
- 5
What was Vietnamisation?
Model answer
Vietnamisation was Nixon's policy of withdrawing American troops while building up South Vietnamese forces to carry on the fighting.
- 6
Why did the invasion of Cambodia in 1970 cause such an outcry?
Model answer
Nixon widened the war while claiming to be ending it, campuses across the country erupted, and four students were shot dead by the National Guard at Kent State.
