Why was macarther removed from his post?

General Douglas MacArthur was removed from his post as commander of U.S. forces in Korea by President Harry S. Truman in April 1951 due to escalating tensions between MacArthur and the administration. MacArthur publicly advocated for a more aggressive military strategy against China, including the use of nuclear weapons, which contradicted Truman's policy of limited engagement. His insubordination and disregard for civilian control over the military ultimately led Truman to relieve him of duty to maintain authority and coherence in U.S. foreign policy.
