Within days of Pearl Harbor, FBI director J. Edgar Hoover assured the U.S. Attorney General that “practically all” suspected individuals were already in custody, and there was no need for mass evacuations of Japanese for security reasons. But Lt. Gen. John L. DeWitt, head of the Western Defense Command, pushed for wholesale Japanese evacuation. “The Japanese race is an enemy race,” DeWitt wrote, “and while many second and third generation Japanese born on United States soil, possessed of United States citizenship, have become ‘Americanized,’ the racial strains are undiluted.”
West Coast congressmen also agitated for the removal of the Japanese. Los Angeles representative Leland Ford insisted that “all Japanese, whether citizens or not, be placed in concentration camps.” In the end, political pressure prevailed, and the army was empowered to force all West Coast Americans from their homes.
