I agree with QT; “defend the beaches” invites a negative TUV trade, as the USA and UK can bring in air power and bombardments to ensure they wipe out your stacks. Paris is all you need to stock with artillery and slow movers, even mechs newly built from WG can protect that key zone and fight any of the 3 beachheads. If you do it that way, Germany brings air on the counterattack, rather than the Allies getting to use theirs.
Your american player is splitting, which is why he’s declined to strongarm SZ 6. They can still attack Japan, but they cant screen SZ 19 so your fleet could reply.
The small allies may counterattack, but Japan’s next turn can be spent consolidating fleets. Based on all these details, USA has missed its chance to really mess with you. Your purchases should be armor, or more factories. More sea units really aren’t needed if the USA is going to back down like that. The ships that bombard (and 1-2 CV) can chill down south while the rest of your ships form back up and prepare to ward the US even further away.
With your armor and fleet, india should fall pretty easily. Then, the transition to ANZAC or Africa–anzac has minimal reserves and could be easily taken. If you gather back up, threaten hawaii, and or blow up that US fleet, that’s your sixth VC and you win.
