The domino theory suggests that if one country falls to communism, neighboring countries will follow, like a row of dominoes 🂏. It's based on the idea that political events in one nation can trigger similar events in surrounding nations. This theory gained prominence during the Cold War as a justification for U.S. intervention in Southeast Asia. Think of it as a chain reaction, where one event sets off a series of others. Critics argue it oversimplifies complex political situations and ignores local factors. The domino theory has been used to explain and justify various foreign policy decisions. It implies that containing communism in one country is essential to prevent its spread elsewhere.
