Actually, I’d say you work your way up to building them. After all, for USA Asia is an after-thought. Your primary goal is to get those islands out of Japanese control. They’re worth 13 IPCs which translates into an actual worth of 26 IPCs (+13 for the allies, -13 for the axis) and they effect the one Axis nation that cannot afford their loss.
Japan’s response? Well, they can either attack the American ships giving America a HUGE advantage and hurting their own forces drastically (FTR @ 3 CV @ 1 instead of FTR @4 and CV @ 3, a total of -4 Combat points, or 8 effective combat points) or they can attempt to reclaim islands which ties up their fighters, transports and infantry giving Russia relief, or, they can ignore the loss of their islands, build a home fleet for defense and hope they can take Moscow before America can sink them (this last is probably their best strategy. However, none of these really saves them from loss.)
Meanwhile America is in the best position to do what htey want. A) It’s very difficult for them to hit Europe in Revised (compared to regular); B) They got a production increase which is MORE then what they loose in Asia Minor (+6 over standard, China/Sink only worth combined 4); C) American carriers and fighters defend just as well as Japanese ones, but don’t have as high of an opportunity cost as Japanese carriers do. (16 IPCs from 30 (53.33% is much higher of an opportunity cost then 16 from 42 is 38.09%).
And the final point of consideration is that American territory, except China/Sinkiang, is all but immune from Axis conquest in Revised. (In standard as well, only I’d add Hawaii as a threatened territory on J1.)
Meanwhile, USSR/UK seem to do the majority of action against Germany anyway in Revised. (Assuming America goes through Africa up through Caucasus we’re talking 6 rounds before their infantry can even start to threaten German home territory.)
