Question

the domino theory stated that

Answer 1

The domino theory is a theory which was promoted by American foreign policy analysts during the 1950s and 1960s. According to the theory, nations on the borders of communist nations could be considered under threat, potentially falling like dominoes to communist influence and setting up a situation in which communism would rapidly spread across a region or perhaps even an entire continent. As late as the 1980s, this theory was revived to justify American intervention overseas.
