Answer 1

The answer is the domino theory.

The domino theory, also called the domino effect, is a theory in foreign policy in America. It was first coined by President Harry S. Truman and suggests that if a country fell to communism, then other countries nearby would also likely be affected.

The domino theory comes from the idea of dominoes, that when one topples over, the others follow.
