Question: 1 / 400

What does the domino theory suggest?

If one nation became communist, neighboring nations would too

The domino theory suggests that if one nation falls to communism, it sets off a chain reaction where neighboring nations are likely to follow suit and also become communist. This theory emerged during the Cold War era and was used to justify U.S. involvement in various conflicts, particularly in Southeast Asia. The idea was rooted in the belief that the spread of communism posed a significant threat to other countries in the region, leading to fears of a wider expansion of communist influence. Therefore, the notion that the fall of a single nation could cause a series of similar events in neighboring countries underscored the urgency for U.S. intervention to contain communism globally.
