Naval Station Pearl Harbor
The overall death toll was 2,467 people: 2,403 American citizens—2,335 members of the U.S. military and 68 civilians—and 64 members of the Imperial Japanese Navy. Five U.S. battleships were sunk and the other remaining three were badly damaged. Overall, nine ships of the U.S. fleet were sunk and 21 ships were severely damaged. Three of the 21 would be irreparable. 188 U.S. aircraft were completely destroyed and 159 others were damaged. Japan lost 29 out of the 353 aircraft they attacked with. The attack on Pearl Harbor was the largest destruction of life and property on American soil both in peacetime and in general by foreign nationals prior to the September 11 attacks, and remains the deadliest attack on American soil both in peacetime and in general by a foreign nation.
Presidency of Franklin D. Roosevelt
The attack on Pearl Harbor raised concerns in the public regarding the possibility of sabotage by Japanese Americans. This suspicion was fed by long-standing racism against Japanese immigrants, as well as the findings of the Roberts Commission, which concluded that the attack on Pearl Harbor had been assisted by Japanese spies. The size of the Japanese population in Hawaii precluded mass internment in that territory, but there was strong popular support for the removal of Japanese from the West Coast. In February 1942, President Roosevelt signed Executive Order 9066, which provided for the relocation of hundreds of thousands of Japanese-American citizens and immigrants from the West Coast. They were forced to liquidate their properties and businesses and interned in hastily built camps in interior, harsh locations. Distracted by other issues, Roosevelt had delegated the decision for internment to Secretary of War Stimson, who in turn relied on the judgment of Assistant Secretary of War John J. McCloy. The Supreme Court upheld the constitutionality of the executive order in the 1944 case of "Korematsu v. United States". The internment order was rescinded shortly after the "Korematsu" decision, and Japanese-Americans were allowed to return to the West Coast. Many German and Italian citizens were also arrested or placed into internment camps.
