The Breakdown of the US-Soviet Alliance
The Ideological Differences Between the Superpowers
The Ideological Differences Between the Superpowers
Ideological differences (differences in political ideas) between the USA and Soviet Union led to emerging tension and distrust. A ‘Cold War’ refers to a conflict fought in every way except direct fighting between the 2 sides.


Truman and the USA
Truman and the USA
- Truman became president of the USA after Roosevelt’s death.
- He was less sympathetic towards the communist dictatorship in the Soviet Union.
- Roosevelt had held the alliance together and after his death. Truman’s approach was more hard-line.


Stalin and the Soviet Union
Stalin and the Soviet Union
- Stalin was distrustful of Truman, who demanded lots of things at Potsdam.
- He was angry that, before the conference, Truman had successfully tested the atomic bomb without consulting him.
- However, Stalin was already aware of the progress the USA was making.


Churchill and Britain
Churchill and Britain
- Churchill believed that a defeated Germany should be rebuilt.
- But Stalin wanted to weaken Germany as much as possible through reparations.
- Churchill also suspected that Soviet troops would not leave the Eastern European countries that they had liberated.
- Britain’s economy had been severely impacted by the war, and it could not act against the Soviet Union on its own.
- As a result, it allied more closely with the United States.
- This process led to the divisions which would become known as the Cold War.


Capitalism vs communism
Capitalism vs communism
- The Soviet Union supported communism, whilst the USA and Britain were capitalist countries.
- Communism advocated confiscating all private property, with the government owning all assets and controlling all enterprise. Communism stood against capitalism and liberal democracy.
- Capitalism advocated that entrepreneurs and businesses compete via innovation to create the best goods & services for consumers, with a large portion of the benefit of their work going to the business.


Capitalism vs communism illustrated
Capitalism vs communism illustrated
- In communism, Boris Johnson or Theresa May's central team would have to design Twitch, Snapchat, TikTok, Tesla, McDonalds, YouTube and Spotify, whilst the workers that they hire would not have an incentive to work hard and make good products.
- In capitalism, individuals create businesses and pay workers depending on how easily they can be replaced. If the business succeeds, the entrepreneur can become very wealthy like Mark Zuckerberg or Jeff Bezos. Evan Spiegel starts Snapchat to make a better service to fit how he wants to message people. Spiegel has the information and the incentive, but can make a huge amount of money building Snapchat. This increases inequality and everyone does not earn the same amount of money.
