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.
Franklin D. Roosevelt
The Japanese were incensed by the embargo and Japanese leaders became determined to attack the United States unless it lifted the embargo. The Roosevelt administration was unwilling to reverse policy, and Secretary of State Hull blocked a potential summit between Roosevelt and Prime Minister Fumimaro Konoe. After diplomatic efforts to end the embargo failed, the Privy Council of Japan authorized a strike against the United States. The Japanese believed that the destruction of the United States Asiatic Fleet (stationed in the Philippines) and the United States Pacific Fleet (stationed at Pearl Harbor in Hawaii) was vital to the conquest of Southeast Asia. On the morning of December 7, 1941, the Japanese struck the U.S. naval base at Pearl Harbor with a surprise attack, knocking out the main American battleship fleet and killing 2,403 American servicemen and civilians. At the same time, separate Japanese task forces attacked Thailand, British Hong Kong, the Philippines, and other targets. Roosevelt called for war in his famous "Infamy Speech" to Congress, in which he said: "Yesterday, December 7, 1941 — a date which will live in infamy — the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan." In a nearly unanimous vote, Congress declared war on Japan. After the Japanese attack at Pearl Harbor, antiwar sentiment in the United States largely evaporated overnight. On December 11, 1941, Hitler and Mussolini declared war on the United States, which responded in kind.
