It's the Proxy War.
Proxy wars were common in the Cold War, because the two nuclear-armed superpowers (the Soviet Union and the United States, and to some extent, China) did not wish to fight each other directly, since that would have run the risk of escalation to a nuclear war. Proxies were used in conflicts such as Afghanistan, Angola, Korea, Vietnam, the Middle East, and Latin America. The first proxy war in the Cold War was the Greek Civil War, which started almost as soon as World War II ended. The Western-allied Greek government was nearly overthrown by Communist rebels with limited direct aid from Soviet ally or client states in Yugoslavia, Albania, and Bulgaria.
