Thus, Admiral William Halsey, soon to become commander of the South Pacific Force, vowed after Pearl Harbor that by the end of the war the Japanese language would be spoken only in hell, and rallied his men thereafter under such slogans as "Kill Japs, kill Japs, kill more Jap." Or as the U.S. Marines put it in a well-known variation on Halsey's motto: "Remember Pearl Harbor- keep 'em dying."
