Why did Truman removed general Douglas MacArthur from command of United Nations forces in Korea?

President Harry S. Truman removed General Douglas MacArthur from command of United Nations forces in Korea primarily due to escalating tensions between MacArthur and the administration regarding military strategy and policy. MacArthur advocated for an aggressive approach, including potential attacks on China, which Truman feared could lead to a broader conflict. Additionally, MacArthur's public statements undermined Truman's authority and contradicted the administration's stance on limited war. Ultimately, Truman prioritized maintaining civilian control over the military and the broader geopolitical implications of the Korean War.
