The domino theory heavily influenced the United States' role in the Vietnam War by convincing the government to become involved in the war. The domino theory, popularized by President Dwight D. Eisenhower, posited that if one country in Southeast Asia fell to communism, neighboring countries would also fall like dominos. This theory fueled the fear of communism spreading throughout the region and the world. The United States believed that if South Vietnam fell to communism, it would trigger a chain reaction, leading to the spread of communism in other areas such as Laos, Cambodia, and eventually, the rest of Southeast Asia. In an effort to prevent this, the United States committed significant military forces and resources to support South Vietnam in its fight against communist North Vietnam. This involvement escalated over time and led to the full-scale deployment of American troops and ultimately the Vietnam War.
