Why was General Douglas MacArthur removed from command in 1951 by President Truman?

General Douglas MacArthur was removed from command in 1951 by President Truman primarily due to escalating tensions over military strategy during the Korean War. MacArthur advocated for a more aggressive approach, including attacks on China, which Truman believed could lead to a broader conflict. Additionally, MacArthur's public statements undermined presidential authority and policy, prompting Truman to relieve him to maintain civilian control over the military.
