South Korea--China and USA went to prevent the Domino Theory--- if one country becomes communist, all the countries around it will too.
Containment
The government policy of containment of communism. It was felt that if a country became communist that the nearby countries would follow. This was called "domino effect" and ruled American foreign policy for 60 years. To some extent it still does,but the players have changed .
The United States effectively abandoned its containment policy during the Vietnam War. Initially aimed at preventing the spread of communism in Southeast Asia, the war's unpopularity and subsequent U.S. withdrawal in 1973 signaled a shift in foreign policy. This marked a move away from direct military intervention and containment strategies, leading to a period of détente and a reassessment of U.S. involvement in global conflicts.
