Although I think you already understand this, it should be said that what I like about these set ups are their versitilty to make attacks on Germany or Japan from these positions depending on the opportunity presented by Axis set ups and where they are needed most.
It’s good to have options.
The part I am struggling with and trying to find an alternative to is when Japan is removing the US options to add to this by attacking Pearl Harbor.
Which may be the correct thing for Japan to do here although I consider the Pearl Harbor attack to not be ideal, because it does disrupt the US part of the chain.
