@blacky:
I never played this simply because the US has enogh to do to fight Japan. Sending 16 ground Units and 8 Transports + Navy to Gibraltar leaves the Japanese ungarded. I think an experienced Axis player will love that Allied strategy.
With a large Atlantic US1 buy, as well as a little maneuvering, the US has plenty of resources to go for Spain while still putting plenty of time and money into the Pacific.
Let’s say the US buys 3 transports, 1 inf, 1 CV and 2 subs. Bring the 2 inf from WUS over to CUS, load the transport in SZ 10 and move it, along with the loaded CV and a DD, to SZ 89, swing the fighter in EUS over to WUS to replace the one you’re taking from that CV.
Place 3 transports, and 2 inf in the Atlantic, and the rest in the Pacific.
The US now has 5 loaded transports, a loaded CV and a bombardment hit ready for Spain on US2 (they could even get the bomber there if they felt it could safely land in Morocco or Gibraltar). US should survive that battle with 7-8 ground units.
The buy for US2 could be either one transport, one inf in the east, with the rest of the money going to the pacific. From there on out, you have 3 transports coming and going between 91 and 101, dropping six units a turn (4 inf and 2 art for 20 IPC) while spending the rest in the Pacific.
So in return for one turn of the US going heavy in the East, they can drop 6 guys in Spain a turn (9 if they buy a factory) while spending most of their money in the Pacific.
A little help from the UK will go a long way to helping with this.
