If you are asking when the US entered WW2, it was after the Empire of Japan suddenly and deliberately attacked the United States naval base at Pearl Harbor, Hawaii, completely destroying multiple warships, most of which are in the battleship class. Japan aattacked because the United States controlled the Philipines and the rich oil fields there. After some involvement in China, the US boycotted sales of oil to Japan. Japan could not survive without the oil, so they had to attack the US and gain access to the Philipines. They decided to attack the heart of our naval empire: Pearl Harbor.
