What was the central goal of the united states in the korean war? block chinese expansion into north korea prevent south korea from invading japan contain the spread of communism eliminate soviet influence in east asia

The correct option is " contain the spread of communism "

The Korean War took place between 1950 and 1953. Its components were the Republic of Korea (or South Korea), supported by the armed forces of several countries commanded by the United States; and the Democratic People's Republic of Korea (or North Korea), supported by the People's Republic of China and the Soviet Union. The war was one of the earliest episodes of the Cold War. Excluding more than 3 million civilians and almost 15% of the population of the dead North, it constitutes one of the most bloodthirsty wars in history.
