If you don't know what Pearl Harbor was, you suck. The Japanese bombed Pearl Harbor, HI on December 7th, 1941. After that, the US entered World War II. (And no, I didn't have to look it up to tell you that, this next part I did, cause I didn't want to screw it up). Out of the 8 battleships in the harbor, the Arizona, was the only one that stayed at the bottom of the ocean. 2,403 American servicemen, and 68 civilians were killed during the attack. So, if you don't know your country's history (don't tell me, but) go visit Wikipedia and find out about it.
