Was Douglas McArthur charged with insubordination?

General Douglas MacArthur was not formally charged with insubordination, but he was relieved of his command by President Harry Truman in April 1951 due to his public disagreement with U.S. policy regarding the Korean War. MacArthur's actions, including his statements advocating for an expansion of the conflict, were seen as undermining civilian authority, which led to his dismissal. This decision sparked significant controversy and debate at the time.
