a. the United States had a capitalist system while the Soviet Union had communist system with central planning
Explanation:
The Cold War on European soil was largely because of economic reason. Western Europe was under the influence and to a certain degree under the control of the United States, and they all wanted capitalist systems. Their goal was to make all the economies open, so that there's a free movement of capital through them without any problem, with the private ownership being the one that have the main say in the economy. The Soviet Union and its allies had different politics though. They wanted and practiced communism, so they wanted to spread the central planning, thus the command economy type, and all the countries to be self-sustaining, with the government being the only economic power in the country.
