Explanation:

The domino theory was the basis for the United States strategy of containment, and the reason for the U. S. to enter the Vietnam War. The Vietnam War was a result of the national strategy of containment. The national strategy of containment demanded the U. S. stop communist aggression into the countries of Southeast Asia. This strategy was developed from a belief in the domino theory. The domino theory basically stated if one new country went communist in Asia then it would begin a chain reaction that would cause several more Southeast Asian countries becoming communist.
