Japanese-American Claims Act
The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy on the United States naval base at Pearl Harbor in Honolulu, Hawaii, on the morning of December 7, 1941. The attack sank four U.S. battleships, destroyed 188 U.S. aircraft, and killed 2,403 U.S. citizens within two hours, and led to the United States joining World War II. Once the United States entered the war and anti-Japanese sentiment began to circulate, Americans increasingly reacted with racism and hostility, viewing people of Japanese descent were treated as enemies regardless of whether they were U.S. citizens. The U.S. government expressed concerns about the loyalty of the Japanese people living in America and about Japanese spies sending information to Japan. "The U.S. Department of the Treasury froze the assets of all citizens and resident aliens who were born in Japan, and the Department of Justice arrested some 1,500 religious and community leaders as potentially dangerous enemy aliens. Because many of the largest populations of Japanese Americans were in close proximity to vital war assets along the Pacific coast. The result was President Franklin D. Roosevelt's Executive Order 9066."
George Marshall
After World War II ended, the Congressional Joint Committee on the Investigation of the Pearl Harbor Attack received testimony on the intelligence failure. It amassed 25,000 pages of documents, 40 volumes, and included nine reports and investigations, eight of which had been previously completed. These reports included criticism of Marshall for delay in sending General Walter Short, the Army commander in Hawaii, important information obtained from intercepted Japanese diplomatic messages. The report also criticized Marshall's lack of knowledge of the readiness of the Hawaiian Command during November and December 1941. Ten days after the attack, Lt. General Short and Admiral Husband E. Kimmel, commander of the Navy at Pearl Harbor, were both relieved of their duties. The final report of the Joint Committee did not single out or fault Marshall. While the report was critical of the overall situation, the committee noted that subordinates had failed to pass on important information to their superiors, including Marshall.
