I voted other, for Navy + Air. I wasn’t sure if that was included in the all navy option.
I also think you need you immediately go 100% Pac once it is clear the US is all in. A few inf for Asia is fine, but given what you start with you really shouldn’t have trouble getting the 3-4 northern Russian territories the 4 US and probably Burma. Beyond that you have to make sure the US can’t creep up on your islands, so I’d be going all in on Navy/Air. Ftrs are a good all purpose buy. If you can get a massive fleet out to Phil Is or Car that helps immensely. Anything based too close to the coast or too far north/south allows the US to dance around and pick off islands one at a time while using DDs as blockers.
I’d stay away from too many transports, cause they can’t defend and you’ll never be able to fill them all once US starts to venture out. I’d stay away from ICs (you can get away with one in Man), b/c again they can’t defend, you won’t need the slots b/c of the cost of buying navy and air, and finally it is something you are going to have to defend. I’d also limit bomber buys. They are great at offense and project a large threat area, but they cannot defend a sz, whereas with a ftr you can just drop an AC. That’s not to say don’t buy bombers, just that you need to be aware of the defensive limitations when you make the purchase.
