Japan attacked Pearl Harbor because the U.S. enacted an embargo on all oil supplies to Japan. The reason for the embargo is because Japan was invading China. The U.S. embargo cut-off 90% of Japans resources, which crippled their economy and most importantly military. Japan attacked Pearl Harbor for another important reason. Pearl Harbor was the home of the U.S. Pacific Fleet. Japan did not want the U.S. in the war because the U.S. at this time had the greatest Naval force. They concluded that if the Pacific Fleet was destroyed, Americans would feel de-moralized and not want to fight. Additionally, an attack on the Pacific Fleet would take the U.S. six months to recuperate and rebuild the Navy.
