Folks,
I've been reading "Shattered Sword" and was running a few what-if questions around in my head. Let's say that starting around 1935 you have the power to make any changes to the Japanese navy. Resource limits still apply, policical issues go the same way so still bad relations with the Japanese Army and the United States, etc. The only thing you can change is THREE naval decisions, policies, etc using hindsight on what happened in our TL.
What decisions would you make (again, you cannot avoid war with the US or the war in China) to improve Japan's naval performance in WWII?
For example, would the steel and other resources from the Yamato class = X fleet carriers? Create a policy to deal with protecting your sea lanes (against subs, for example) rather than just on offensive naval battles, loosen the graduation requirements for naval aviation school, etc...
