For all the hilarity, the Japanese aims are probably more practical than Marshall's ideas about invading France in 1942....
Actually, the plan is sensible in what it aims to do. The problem is the Japanese don't have the ships and planes to achieve it...
And is it likely to survive the Doolittle Raid? Might we actually see a Midway after all as the Japanese put aside what passes for their version of strategic logic in favour of avenging the humiliation?
