your answer

Explanation:

The Domino Theory is a geopolitical theory, prominent during the Cold War, suggesting that if one country in a region falls to communism (or a certain ideology), adjacent countries will follow like a row of falling dominoes. It was used to justify U.S. intervention in places like Vietnam, as policymakers feared the spread of communism across Southeast Asia.

Answer:

The Domino Theory is a geopolitical concept (prominent in the Cold War era) stating that the spread of an ideology (e.g., communism) in one country will trigger similar spread in neighboring countries, likened to a row of dominoes falling. It was used to rationalize interventions (e.g., U.S. in Vietnam) to prevent regional ideological takeovers.
