The attack on Pearl Harbor was the direct event that brought the United States into World War 2. Although the US had been actively supported the Allied cause for years it took the bombing of Pearl Harbor to cause the United States to become a belligerent nation.

Before the attack the USS Ward detects and engages a Japanese submarine, so I proposed that the United States had started the conflict in the Pafic hours before the attack. I proposed this not to dimish the attack on Pearl Harbor and other military bases in Hawaii, but just to get people thinknig that not everything is black and white.
