UN forces continue to press on in Korea

MacArthur quickly achieved the original goal of the UN of removing removing North Korean troops from South Korea, but the Americans did not stop. Despite warnings from China that if they continued they would join the war, the UN approved a plan to advance into North Korea. By October, US forces had reached the Yalu River and the border with China. It was clear that MacArthur and Truman wanted to remove communism from Korea fully.
