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."
United States Navy Dental Corps
Two Dental Corps officers were killed and four were wounded in the attack on Pearl Harbor in 1941; they would not be the last dental officers to die in the line of duty. As the US got ready for world conflict, Navy Dentistry's active duty numbers swelled to its highest levels ever – ultimately reaching 7,000 dental officers and 11,000 dental technicians. Active in nearly every engagement during the war, dental personnel who were assigned to operational units in the South Pacific often assisted in emergency medical operations ashore, especially facial trauma requiring surgery. Numerous dental officers were killed in action aboard war ships and in major battles in Guadalcanal, Tarawa, Saipan, and Iwo Jima. For their heroic efforts, 93 dental officers received personal awards, including the Silver Star, the Legion of Merit, the Navy and Marine Corps Medal, and the Bronze Star Medal.
