effort was made to locate and to review the records of government action and to analyze other sources of information including contemporary writings, personal accounts and historical analyses…. . .Executive Order 9066 was not justified by military necessity, and the decisions which followed from it—detention, ending detention and ending exclusion—were not driven by analysis of military conditions. The broad historical causes which shaped these decisions were race prejudice, war hysteria and a failure of political leadership. Widespread ignorance of Japanese Americans contributed to a policy conceived in haste and executed in an atmosphere of fear and anger at Japan. A grave injustice was done to American citizens and resident aliens of Japanese ancestry who, without individual review or any…evidence against them, were excluded, removed and detained by the United States during World War II. Source: In 1980, Congress established the Commission on Wartime Relocation and Internment of Civilians to investigate the detention program and the constitutionality of Executive Order 9066. The Commission released its report “Personal Justice Denied: The Report of the Commission on Wartime Relocation and Internment of Civilians” on February 24, 1983. The passage above is an excerpt from this report.
