Some causes of the Attack on Pearl Harbor are....
The Holocaust and Nazi Germany. Nazi Germany was one of the bigger causes since they started the war, and the Holocaust was a even bigger cause because the Holocaust made the rest of the world fight back. Another cause of the Attack on Pearl Harbor was that Japan was desperate. Japan was isolated and had no allies, so they hoped that attacking America would side them with the Germans. Also, they thought that America's involvement in the war was inevitable, and that if they didn't attack America, America would end up attacking them.
