Answer:
1: The United States and Soviet Union's goals clashed with one another due to their fundamentally different ideologies. The United States was committed to democracy, capitalism, and the spread of American-style freedom, while the Soviet Union was committed to communism, state control of the economy, and the spread of Soviet-style socialism. These competing ideologies led to tensions between the two nations as they sought to promote their own political and economic systems in the post-war world.
2: Economics played a role in post-war tension as the US and Soviet Union had different economic systems. The US economy was based on capitalism, where private ownership and market forces drive economic activity. The Soviet economy, on the other hand, was based on socialism, where the state controlled the means of production. This led to a competition between the two nations to promote their economic systems as the best way to rebuild war-torn Europe and ensure economic prosperity.
3: The end of WWII lead to tension between the US and the Soviet Union as the two nations had different visions for post-war Europe. The US wanted to rebuild Europe through the Marshall Plan, which provided economic assistance to European nations to rebuild their economies and promote democracy, which was seen as a threat to the Soviet Union's communist ideology. The other example is the formation of NATO(North Atlantic Treaty Organization) which was a military alliance formed by the US, Canada, and several Western European nations. The Soviet Union saw this as a threat to its security and influence in Europe.
