Many military professionals regard General of the Army Douglas MacArthur as a very polarizing figure in military history, from his strategic use of maneuver to defeat the Japanese at Leyte to his public defiance of the Commander in Chief, President Truman on his policy towards the Korean War. Seen by many as a tactical genius, while others viewed him as an egomaniac, General MacArthur exhibited both sides of this complex character, but the evidence shows that MacArthur possessed a level of military competence that set him apart from his contemporaries. In 1950, MacArthur demonstrated one of his most embarrassing defeats as well as one of his most brilliant successes within the course of ten weeks. MacArthur exemplifies a level of confidence that earned him the modern reputation as an operational artist from his ability to turn the tide of war and restore South Korea's sovereignty.
