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."
Doolittle Raid
Despite the minimal damage inflicted, American morale, still reeling from the attack on Pearl Harbor and Japan's subsequent territorial gains, soared when news of the raid was released. The Japanese press was told to describe the attack as a cruel, indiscriminate bombing against civilians, women, and children. After the war, the casualty count was 87 dead, 151 serious injuries, and more than 311 minor injuries; children were among those killed, and newspapers asked their parents to share their opinion on how the captured raiders should be treated. For years before the attack on Pearl Harbor, there had been mock air raid drills in every Japanese city, although China's air force was almost nonexistent; this may have been part of the process of keeping warlike emotion at a high pitch.
