Why Pearl Harbor was Attacked

Knowing the U.S. is gearing up to engage them in the Pacific Ocean theater of World War II, Japan deploys a massive air attack on U.S. Navy ships parked at Pearl Harbor. The surprise assault by 353 Japanese aircraft leads to the deaths of 2,403 people, including 1,177 sailors aboard the ill-fated USS Arizona, one of 19 vessels that were damaged or destroyed in the attack. Nearly 330 aircraft were also damaged or destroyed. The United States declares war on Japan the next day and three days later against Germany and Italy.
