Final answer:
A satellite state refers to a country controlled by another nation, which was evident during the Cold War when the Soviet Union had control over the Eastern European countries. The Soviets wanted these satellite states as a buffer zone against Western Europe and to expand their influence and control.
Step-by-step explanation:
A satellite state is a country controlled by another nation. In the context of the Cold War, the term satellite state referred to the Eastern European countries that were under Soviet control. These countries were not fully independent, and their governments were typically pro-Soviet and aligned with the policies and interests of the Soviet Union. The Soviets wanted satellite states for several reasons. One of the main reasons was to create a buffer zone between the Soviet Union and Western Europe to protect themselves from potential invasions. Additionally, having satellite states allowed the Soviets to spread their influence and extend their control over a larger territory.
