Domino theory

Answer 1

The domino theory is a political theory that was widely believed during the Cold War. The theory suggested that if one country in a region were to fall under the influence of communism, then the neighboring countries would also eventually fall, like a row of dominoes. The United States government used this theory to justify its intervention in various countries, as it feared that the spread of communism in one country would lead to a domino effect, ultimately resulting in the collapse of other countries in the region. The domino theory played a significant role in the U.S. involvement in the Vietnam War, as the U.S. aimed to prevent the spread of communism from North Vietnam to South Vietnam and potentially to other parts of Southeast Asia. However, the domino theory was ultimately proven incorrect, as the spread of communism did not have the dramatic and widespread consequences that were initially feared.
