About Joseph Grew

Joseph Clark Grew was an American career diplomat and Foreign Service officer. He is best known for his long tenure as United States Ambassador to Japan (1932–1941) in the lead-up to Pearl Harbor and for his two stints as the second-in-command at the State Department. He opposed American hardliners and sought to avoid war. When the war ended, he helped draft the U.S. Initial Post-Surrender Policy for Japan, which offered relatively generous terms to the defeated Japanese, which facilitated America's peaceful post-war occupation of Japan.
