The Japanese bombed our fleet in Pearl Harbor so that the US would have no way to stop them from taking over the rest of the Pacific Rim.
They had already taken Manchuria (renamed Manchukuo) and China. They destroyed had the British military power in the Pacific. The only obstacle left was the US Fleet.
They made two major miscalculations; one, the carriers were not in the harbor and, two, the ability of the US to respond industrially was grossly underestimated.
So, Kendall and Whistlestop, if a country doesn't get it's way and doesn't have many natural resources and no one will sell them what they want, then military adventurism and invasion of other countries is acceptable.
What a NOVEL idea!
