The “domino theory” is the idea that…It applies to the conflict in Vietnam because…

The “domino theory” is the idea that if one country in a region falls to communism, then neighboring countries will also fall like a row of dominos. It applies to the conflict in Vietnam because the US government feared that if South Vietnam fell to communism, then other countries in Southeast Asia would also become communist, leading to a domino effect that would threaten the stability of the entire region. This theory played a significant role in the decision to enter the conflict in Vietnam, as the US saw their involvement as necessary to prevent the spread of communism and maintain their strategic interests in the region. Ultimately, the “domino theory” influenced US foreign policy and military strategy in Vietnam, shaping the course of the conflict.
