Final answer:
The 'Somebody Wanted-But-So' chart for the Korean War illustrates the different objectives and outcomes for key players such as North Korea, General MacArthur, President Truman, China, and the United Nations, highlighting their respective desires, the obstacles they faced, and the results of their actions.
Step-by-step explanation:
North Korea wanted to unify Korea under communism but faced opposition from South Korea and international forces led by the United States, so it invaded South Korea, starting the Korean War.
General MacArthur wanted to conduct military operations to repel North Korean forces and later to push into China but was limited by President Truman's policy to avoid a larger war with China, so he was eventually relieved of command.
President Truman wanted to contain the spread of communism without escalating into a larger conflict but faced an aggressive North Korean push and pressure from military leaders, so he maintained a limited war strategy, which included firing General MacArthur.
China wanted to support the spread of communism and prevent a US-dominated Korea but faced the risk of a broader conflict with the United States, so it intervened to support North Korea, preventing the collapse of its communist neighbor.
United Nations wanted to restore international peace and stability but faced complex geopolitical challenges in Korea, so it authorized a coalition force to defend South Korea and reestablish the status quo at the 38th parallel after three years of conflict.
