What did president Truman do to general MacArthur?

President Harry Truman relieved General Douglas MacArthur of his command during the Korean War in April 1951. The decision was primarily due to MacArthur's insubordination and public disagreements with Truman's military strategy and policies, particularly regarding the expansion of the war into China. Truman's action underscored the principle of civilian control over the military and aimed to maintain a unified approach to U.S. foreign policy. MacArthur's dismissal was met with mixed reactions, including significant public support for the general.
