Study notes
From the checked teaching notes for this specification point.
The idea
The US monopoly on nuclear weapons, demonstrated by the atomic bombing of Japan in 1945, dramatically increased US-Soviet tensions. Stalin viewed the bomb as a tool of American intimidation, prompting an accelerated Soviet nuclear programme. Mutual suspicion was formalised in 1946 through secret diplomatic reports. Kennan's Long Telegram advised Washington that the USSR was aggressively expansionist, laying the groundwork for containment. Conversely, the Novikov Telegram warned Moscow that the US was striving for world supremacy. This diplomatic breakdown was physically manifested in Eastern Europe, where Stalin rigged elections and used the Red Army to establish communist satellite states, confirming Western fears of Soviet expansionism and destroying the wartime alliance.
What earns the marks
- Explain how the US atomic bomb increased tensions by making Stalin feel threatened and triggering a nuclear arms race.
- Detail the Long Telegram's role in shaping US policy by characterising the Soviet Union as an expansionist threat that must be contained.
- Detail the Novikov Telegram's role in shaping Soviet policy by characterising the US as an imperialist power seeking global dominance.
- Describe the process and impact of creating Soviet satellite states (e.g., Poland, Hungary) as a violation of the Yalta agreements, which heightened Western fears.
Common mistakes and how to put them right
Confusing the authors and recipients of the telegrams.
Put it right: Kennan wrote the Long Telegram to the US government, while Novikov wrote his telegram to the Soviet government.
Stating the Soviet Union had the atomic bomb in 1945.
Put it right: Clarify that the USA had a nuclear monopoly until the Soviet Union successfully tested its first atomic bomb in 1949.
Describing satellite states as part of the USSR.
Put it right: Explain that satellite states were legally independent countries in Eastern Europe that were politically and economically controlled by the Soviet Union.
Exam tips
- Link the atomic bomb directly to the breakdown of trust, noting that Truman did not inform Stalin about it until the Potsdam Conference.
- Use the Long and Novikov telegrams as evidence of how both superpowers perceived the other as an existential threat by 1946.
- Provide specific examples of satellite states, such as Poland or Czechoslovakia, to strengthen your explanation of Soviet expansion.
