Douglas MacArthur is best remembered for his ability to adapt, a quality that catalyzed his greatest accomplishments. Adaptability has become an indispensable trait for military leadership in an era of technological leaps that guarantee the nature of war will radically change during the span of an ordinary career. One of the first proponents of a new dimension in warfare - the Air Force - MacArthur was also unmatched historically for his management of peace during the U.S. occupation of Japan. For generations to come, MacArthur's legacy will yield profitable - and entertaining - examples to Americans in and out of uniform.
