Reasons for Breakdown of USA-USSR Relations

  • Fought between USA and USSR for 40 years
  • Divided Europe into two blocs (countries grouped by an alliance or ideology) at end of 1949
    • First bloc included those who were under Soviet control
    • Second bloc included those that benefited from relations with the US (mostly members of NATO)
    • Germany was initially split into four, but eventually became 3 western zones (officially known as West Germany altogether) and 1 eastern one (officially known as East Germany)
  • The US blamed USSR for spreading communism
  • The USSR defended itself by claiming that it was a protective measure and blamed the US for building a central economic empire with itself at its center. The USSR viewed this as a threat and used this fact to justify its extreme methods of protection


The relations between USA and USSR became more hostile because of a number of reasons

  • Conflict in Ideologies
    • US was a capitalist democracy, allowing freedom in culture and the market with rights being a key attribute of life in the US
    • USSR was a communist state, with little freedom of belief and no political opposition granted and a state-controlled economy
    • There were also previous instances which increased tensions
      • US and British intervention against the Communists in the Russian Civil War
      • USSR’s Nazi-Soviet Pact
    • Western powers were wary of USSR
      • Feared that Communists shared similar intentions with the previous Tsarist government to gain territory in Central Europe and the East Mediterranean
      • High-ranking Communists had mentioned revolution and the spread of communism outside of the USSR on a worldwide scale
    • This caused a unstable relationship in WW2
  • Wartime Alliance and Relationships
    • After Germany invaded USSR in 1941, the image of the alliance of the US, Britain and USSR seemed very cooperative and it seemed like they were on good terms
    • This was shown by
      • The inconvenient journey of British ships across the Baltic to provide resources to the USSR
      • The Lend Lease Programme (the selling, lending, and renting of weaponry) granted by US to USSR
    • However, in reality, the relations between these three countries were tense
      • Stalin kept secrets and did not share information about his plans in the war
      • Churchill refused to share knowledge of Enigma codes (coded messages used for the communication of German forces) after the British broke the code
      • British and American pilots protested about how Russians seemed to have a lack of trust for them
      • Foreign sailors carrying supplies were often given a small budget. The fact that they had to move across Russian ports under strict control made this worse
      • A lot of unreliability and questioning of methods within this relationship
