The primary reason that the US decided to enter into the conflict in Vietnam can be explained by the “domino theory.” What is this theory and how does it apply here? Explain in a fully developed paragraph.
The “domino theory” is the idea that if one country in a region comes under communist control, neighboring countries will also fall like a row of dominoes. This theory was used to justify the US involvement in Vietnam, as the US feared that if South Vietnam fell to communism, the rest of Southeast Asia would follow suit. The US saw Vietnam as a crucial battleground in the Cold War struggle against communism and believed that they had to prevent the spread of communism in order to protect the interests of the United States and its allies. This theory played a significant role in shaping US foreign policy in Vietnam and ultimately led to the US becoming more deeply involved in the conflict than originally intended.
