Why was Douglas MacArthur fired from his position by President Truman?

Douglas MacArthur was fired by President Truman primarily due to disagreements over military strategy during the Korean War. MacArthur advocated for a more aggressive approach, including the potential use of atomic weapons against China, which conflicted with Truman's goal of containing the conflict and avoiding a broader war. Additionally, MacArthur's public statements undermined Truman's authority and civilian control of the military, leading to a breakdown in trust between the two leaders. Ultimately, Truman prioritized maintaining a unified command structure and preventing escalation.
