History of Hawaii
Pearl Harbor was surprisingly attacked on December 7, 1941 by the Imperial Japanese Navy, killing 2,403 people and sinking the main American battleship fleet. Fortuitously, the four Pacific aircraft carriers were not in port and escaped damage. Hawaii was put under martial law until 1945. Unlike the West Coast of the United States in which 100,000 ethnic Japanese citizens were interned, the Japanese American population in Hawaii completely avoided such similar fate, though hundreds of pro-Japan leaders were arrested. Pearl Harbor was the U.S.' main forward base for the Pacific War. The Japanese tried to invade in summer 1942 but were defeated at the Battle of Midway. Hundreds of thousands of American soldiers, sailors, Marines, and airmen passed through on their way to the fighting.
American propaganda during World War II
Earlier, people complained that the government was covering up the extent of the damage at Pearl Harbor, although this was partly to keep it from the Japanese. The Japanese had a good idea of the damage they inflicted, so only Americans were kept ignorant. One reporter reported, "Seven of the two ships sunk at Pearl Harbor have now rejoined the fleet." Although complaints of news suppression continued, both the newspapers and radio took favorable news and embellished it, a process not countered by the government.
