Douglas MacArthur was a five-star general born in 1880 in Little Rock, Arkansas. He had a long military career, serving as the commander of allied forces in the Southwest Pacific during World War II. There, he oversaw key campaigns like the seizure of Iwo Jima and Okinawa and helped reconstruct Japan after the war. During the Korean War, MacArthur's statements against President Truman's policies led to Truman relieving MacArthur of duty in 1951.
