OCR GCSE History A (J410) — International Relations Period Study
Arguments For and Against the Domino Theory
| Argument For Significance (Containment Failed) | Argument Against Significance (Containment Survived) |
|---|---|
| The Domino Theory partially materialized as communism spread to neighbouring Laos and Cambodia in 1975. | The theory was largely discredited because key regional nations like Thailand, Malaysia, and Indonesia remained capitalist. |
| SEATO was disbanded in 1977 as its primary goal of maintaining a non-communist Indochina was entirely shattered. | The US adjusted its strategy via the Nixon Doctrine, maintaining a "nuclear umbrella" but forcing allies to provide their own ground troops. |
Students often state that the Tet Offensive was a military defeat for the USA. In reality, it was a severe military defeat for the Vietcong, but a devastating psychological and political disaster for America.
For 'Analyse' questions on US withdrawal, do not just list reasons independently. Examiners reward answers that show interconnected causes, such as how the $84 billion annual cost directly fuelled the Anti-War Movement's anger over cancelled domestic social programs.
When evaluating international relations, explicitly contrast the regional failure of Containment in Vietnam with the global success of Détente, demonstrating how the war forced the US to negotiate SALT I and ease tensions with the USSR and China.
