Hi again,

The temporary division of Korea along the 38th parallel was a success for the policy of containment, as communism did not spread into South Korea. In 1954, SEATO (South East Asian Treaty Organisation) was set up as a copy of NATO. Communism had been prevented in South Korea and the UN was seen as a success.

so your answer is,

Widespread fear of communism.
