23 of 46

Consequences of the Korean War-Implemantation of N

Did the war see continuity or change in America's conduct of the Cold War?

Implementation of NSC 68

  • US falsely assumed USSR was behind south Korean invasion and so thought this could happen elsewhere in the world, US had to be ready to fight communism around the globe
  • Truman now supported militarisation as US needed to achieve parity of conventional forces and remain its nuclear superiority. Spend a lot of money on doing this.
24 of 46

Consequences of the Korean War-Strengthening of NA

  • The organisation was strengthened and enlarged. (1951 Greece and Turkey)

Consequences of the Korean War-Restoration of Sove

  • Korean war had been the source of an economic boom for Japan as during it the US placed $3 billion of war related orders in Japan.

  • Japan and the non-communist countries of south-east Asia must be integrated into a regional economy which would guarantee mutual prosperity.
28 of 46

Consequences of the Korean War-Resumption of Aid t

  • Had new military commitments across the world which were reflected in higher levels of defence spending.
  • Brought about the militarisation of US policy as America was now willing to increase military spending to defend the 'free world'.
  • Important as it shaped the course of the cold war.
30 of 46

The 'New Look' Policy

  • 1953 Truman was replaced by Eisenhower.
  • Borught with him a harder line in US policy.
  • Was an approach to containment which rested on the premise that the US would in future be prepared to use nuclear weapons as a first not last resort when dealing with the USSR.
  • Implied US were prepared to engage in Brinkmanship.
  • Consider Massive retaliation as a serious option.

Reasons for the 'New Look'

  • The US were alarmed by the USSR's ideologically motivated expansionist foreign policy and its nuclear capaicty as it had extinguished US atomic monopoly much quicker than they had expected.
  • McCarthy had managed to convince Americans that communist threat was on their doorstep.
  • The policy was a vote winner. There was an increased fear of communsim due to events such as Berlin Blockade, Korean War, China's fall and expansion in eastern Europe.
  • Financial motivation as the threat of the use of nuclear weapons was much cheaper than conventional weapons

Ironically despite all this there was a great improvement in relations during the first three years of Eisenhower's presidency 'The Thaw'.

Leadership Changes in the USSR

  • Further indication that relations could be improved Feb 1956 was the process of Destalinisation.

Benefits of this approach

  • Stable foreign affairs would allow leadership contenders to focus on leadership struggle.

  • Nuclear weapons made war a risky strategy.
  • According to Krushchev there were only two ways, peaceful coexistence or the most destructive war in history.

  • Demonstrated the effect that individual leaders could have on the Cold War.
  • Was short term and gave way to the most dangerous and hostile phase of the CW.
  • Hungary represented continuity in soviet policy as the essential dynamics remained the same. (security concerns and ideological expansion).

Results of the Crisis for Kennedy

  • Building of the wall was a relief as Krushchev had solved the refugee problem without infringing western rights over West Berlin.
