The attack on Pearl Harbor was a surprise attack by the Japanese Naval Air on 7 December 1941 on the naval base of American Pearl Harbor on the island of Oahu, in the archipelago of the U.S. territory of Hawaii, in the heart of the Pacific Ocean. This attack was to destroy the fleet of the Navy that it sheltered and led entry into the Second World War the United States. The attack was ordered by General Hideki Tojo in response to the oil embargo imposed by the United States and launched a surprise the morning of Sunday, December 7 by the Air Service of the Imperial Japanese Navy fleet against the U.S. of Pacific in the port and other forces stationed nearby. This attack is part of the policy of imperial expansion.
