America felt attacked, They tried to remain Neutral through out the war but this was the final straw. Japan had randomly attacked a neutral country out of the blue. "On DEC. 7, 1941, radios buzzed with the news that several hundred Japanese planes attacked a U.S. naval base at Pearl Harbor in Hawaii, killing more than 2,400 Americans as well as damaging or destroying eight Navy battleships and more than 100 planes. Though it would be some time before people learned the full scope of the damage, within days a once-distant war in Europe and the Pacific became a central part of life in the United States, affecting politics, business, media, and entertainment" - Michael Morella.
