Attack Hawaii is mandatory on J1.The Net IPC loss for the allies is way higher than the net loss for Japan. You don’t want that fleet in the Atlantic.
Btw transports > IC on round 1… You can start to think about buying IC’s on J3 or further, you just lack the infantry support to make a decent push to Moscow if you invest in IC’s too early.
Don’t take Hawaii… Just take PH heavily. sub/carrier/2 fighters/bomber or something, the USA can’t waste rescources to Japan if they go KGF and it would cost them a lot to first counter and the delay for Russia will be devistating
