Ok, now this gets going.
US
Happy tidings. US is drawn into the war!
Japan turning into a monster has to be feared. Therefore I propose that main focus of purchases should be in the Pac. Something like 70-90 % for quite some turns. The main purchase for the Atlantic can be trannies and troops, counting on UK to carry the main load of fleet defence. Some air would of course be good to support landings, but that’s a later issue.
Fleet should get into position, with z54 being the priority outpost for now.
China
Taking back Yunnan is top priority, but we can’t expect to hold on to it. China will be run over. We accept that. Just try and weaken the Yellow Plague as much as possible along the way and be a thorn in the side.
UK
I don’t worry squat about Sea Lion, so an idea for a purchase is an ab, fig and inf.
We certainly want to kill of all the pesky subs we can. That will be z106 and z110.
We won’t likely be able to hide our fleet in z109. Maybe it’s possible with buying the fig and having a 5 fig scramble option, which depends on other things like Taranto, so perhaps it’s better to pull them a bit offside by Iceland. With air to scramble there, the bs and cr should be untouchable. That means they can enter the action again in z91 by UK3.
Taranto is nice, but stacking in z92 might be better, saving the fleet and keeping lots of pressure on Italy. That would be the ab in Gibraltar is mandatory. A great asset later on as well, controlling both z91 and z92.
We will certainly hit Tobruk, which will seriously hamper Italy in northern Africa. Air may be used there instead of Taranto, minimizing british losses. Would like to avoid using the tr for an amphi there, since it will just be sunk.
We can skip hitting the italians in Ethiopia, but make priority of grabbing Persia instead.
UK-Pac should probably just go with 5 inf, preparing for the japanese take-down in a few turns.
I haven’t analysed in detail yet, but this is an overall sketch for now.
The British are coming!
