What is the domino theory associated with during the Cold War?

1. The spread of democracy

2. Economic trade alliances

3. The spread of communism among neighboring countries

4. The introduction of new technologies

The correct answer is: The spread of communism among neighboring countries

The domino theory is closely associated with the idea that the spread of communism in one country could trigger a chain reaction, leading to the establishment of communist governments in neighboring countries. This notion was particularly prominent during the Cold War, as it underscored the fear of a Communist expansion in Southeast Asia and beyond, especially after the fall of Vietnam to communism. U.S. policymakers believed that if one nation fell under communist influence, others in the region would subsequently fall, like a line of dominoes. The theory played a significant role in justifying U.S. involvement in various conflicts, most notably the Vietnam War, as the American government sought to contain communism and prevent its spread. Emphasizing the interconnectedness of nations in terms of political ideology, the domino theory highlighted the strategic importance of certain countries in the global landscape during the Cold War era.
