How does evidence shape Domino Theory?

Narrative sequence: answer How does evidence shape Domino Theory by focusing on Part two: Escalation of conflict in Vietnam. Use the chronology of BD Conflict and tension in Asia, 1950-1975, select named evidence connected to Study US involvement, including the Domino Theory, intervention under Eisenhower and Kennedy and the Strategic Hamlets programme, and order events accurately, show movement from one development to the next, and avoid jumping chronology. End by answering the command word directly.

This exam-style task requires a developed historical argument rather than a list of facts. Begin with the relevant period from Paper 1 Section B: Wider world depth studies, then anchor the answer in Part two: Escalation of conflict in Vietnam. The evidence should connect to Study US involvement, including the Domino Theory, intervention under Eisenhower and Kennedy and the Strategic Hamlets programme and be explained through cause, consequence, change, continuity, significance or interpretation as appropriate. A strong final judgement shows why the selected evidence is more convincing than a vague or unsupported claim.
