Answer:
East Germany: the Soviet Union
West Germany: the US
Step-by-step explanation:
The Cold War was a period of fierce tension, mainly between the US and the Soviet Union but also in general between democracy and communism. In fact, after WWII, the Soviet Union and the US decided to split up Germany as war spoils, but each country had its own idea of how their share should be governed. East Germany was controlled by the Soviet Union, under a dictating communist power, while West Germany was controlled by the US with a more democratic approach.
