MacArthur's concept of the role of the soldier as encompassing a broad spectrum of roles that included civil affairs, quelling riots and low-level conflict, was dismissed by the majority of officers who had fought in Europe during World War II, and afterwards saw the Army's role as fighting the Soviet Union. Unlike them, in his victories in New Guinea in 1944, the Philippines in 1945 and Korea in 1950, he fought outnumbered, and relied on maneuver and surprise for success. The American Sinologist John Fairbank called MacArthur "our greatest soldier".
