Which theory held that if one country in Southeast Asia fell to communism, others would follow?

• A. Ho Chi Minh Trail
• B. Geneva Accords
• C. Domino Theory
• D. War Powers Act

Answer: (C)

Domino Theory is the idea that if one country in Southeast Asia falls to communism, neighboring countries will follow in a chain reaction. During the Cold War, American leaders worried that a communist victory in Vietnam could spark similar takeovers in nearby nations, threatening regional stability and U.S. interests. That fear helped drive U.S. involvement in Vietnam and support for anti-communist governments in the region. The other options refer to different things: a supply route used by North Vietnam, a 1954 peace agreement, and a domestic law limiting presidential war powers, none of which express the idea of a cascading spread of communism.
