Where did the Soviet Union set up pro-soviet regimes?

The Soviet Union established pro-Soviet regimes in several Eastern European countries after World War II, including East Germany, Poland, Czechoslovakia, Hungary, Romania, and Bulgaria. These regimes were part of the broader strategy to create a buffer zone against the West and to spread communist ideology. Additionally, the Soviet Union supported similar regimes in Asia, such as in Mongolia and Vietnam, and later in Afghanistan. These actions were integral to the Cold War dynamics as the Soviet Union sought to expand its influence globally.
