JFKs policy that suggests a communist government in one nation would quickly lead to communist takeovers in neighboring states?

Domino theory or domino effect? Which is correct?

The domino effect is the result of the domino theory.

So the Domino Effect is the correct answer. Thank you.

Yes.

Both terms, "domino theory" and "domino effect," are commonly used to describe the idea central to JFK's policy. However, "domino theory" is the more accurate term to refer to the concept.

To better understand the term, "domino theory" suggests that if one country were to adopt communism, it would have a cascading effect on neighboring countries, consequently leading to the spread of communism in those regions as well. This theory was often used during the Cold War era to justify U.S. interventions and involvement in containing communism, particularly in southeast Asia.

You can research the term "domino theory" further by exploring reliable historical sources, such as books, articles, and academic journals, which delve into the topic. Additionally, you can consult reputable online resources, such as encyclopedias or websites specializing in history, international relations, or political science. Keep in mind to use multiple sources to gain a comprehensive understanding of the subject matter.
