Which countries were involved in the conflict known as the Korean War?

• A. North Korea and South Korea
• B. North Korea and Vietnam
• C. South Korea and Japan
• D. North Korea and the United States

Answer: (A)

The conflict known as the Korean War primarily involved North Korea and South Korea. This war began in 1950 when North Korea, supported by the Soviet Union and China, invaded South Korea in an attempt to unify the peninsula under communist rule. In response, South Korea received significant support from the United Nations, particularly from the United States, which led a coalition of forces to defend South Korea. This war lasted until 1953, culminating in an armistice that established the Korean Demilitarized Zone but did not result in a formal peace treaty.

While other nations played crucial roles in the conflict, such as the United States supporting South Korea and China supporting North Korea, the primary adversaries were indeed North and South Korea themselves. Thus, this answer accurately reflects the core participants in the conflict.
