Germany cannot go “hog wild” with a competent UK/Soviet player without some truly decent dice luck. Germany can push up to Moscow, but they often times can’t take Moscow immediately. That, and they can’t really spend their resources in any way but to facilitate as much power as is possible against Russia, or risk losing a turn (or worse, two), toward the eventual goal in the east.
Right about the time the European Axis are crashing the gates or ducking south for that sweet, sweet Caucasus/Volgo/Middle East money, America should be turning around or have already turned around form the Pacific.
On the other hand, Japan fucking can go hog wild without American intervention: J1 DoW specifically. I favor 100% Pac buys as the US (apart from maybe the first 52 or a sub or two a turn or whatever else, depending on a ton of situations that can’t be covered here) because the sooner you can start crumpling up Japan, the sooner you can go try to play hero in Europe.
It might be worth mentioning that Hawaii and Gibraltar are “only” two turns away from one another. It is not impossible to change your mind. It’s usually not the best idea, mind you, but it is an option, and it is occasionally useful.
