Answer 1

The foreign policy strategy that caused the U.S. to become involved in conflicts such as the Korean War and the Vietnam War is the Domino Theory. This theory suggested that the spread of communism in one country could lead to the spread of communism in neighboring countries, much like a row of dominoes falling over. As a result, the U.S. sought to contain communism through military intervention in these conflicts.
