4. What is a ‘superpower’?
A superpower is the term used to describe the most powerful countries. Before World War II there were a number of ‘superpowers’.
Britain, France and Germany were all European superpowers before 1945.
At the end of World War II, all these countries were in ruins or crippled by the long years of war.
The post-World War II world was to be dominated by two superpowers – the USA and the USSR.

5. Differences between the USA and USSR
The USA was a capitalist country, whereas the USSR was a communist country. These countries had very different beliefs.
Capitalism
Where all factors of production (industry, business and agriculture) are owned by private individuals or firms who run them for their own profit.
Communism
Where all factors of production (industry, business and agriculture) are owned by the state for the good of everyone.

Long-term causes of the Cold War
Mutual distrust between two very different countries was the key long-term cause of the Cold War. Why were both sides so suspicious of each other?
The USSR’s worries about the West
Russia had been invaded during World War I (1914), during its Civil War (1918) and during World War II (1941) – they wanted to stop this ever happening again.
Stalin, the leader of the USSR, felt that the West wanted to see communism destroyed. He thought that the West didn’t appreciate the Soviet sacrifices that helped defeat the Nazis in World War II.

Mutual distrust between two very different countries was the key long-term cause of the Cold War. Why were both sides so suspicious of each other?
The USA’s worries about communism
The USA thought the USSR was determined to encourage communist revolutions in other countries, and was worried about communism spreading across the world. This was seen as a dangerous threat to the governments and economies in the West.
The USA ended its policy of isolationism (which they felt had helped Hitler come to power) and thus was determined to prevent what it saw as ‘dangerous dictatorships’ being created again.
