Indeed, I to like to have an open debate without ‘tone’ or disrespect. I want to learn from others, and of course I think I am right sometimes, I have also learnt from this discussion. Next time I play the allies, I will certainly have a different approach. I will try to involve the Russians more and perhaps coordinate in what turn the allies should put pressure on Japan collectively.
But still think Japan is to strong! ;)
Fleet
The allies can buy, but not enough. You can only have a maximum of 19 units at Queensland in US4 (if you buy 3 carriers in US1). Japan has around 35 at that time (and can buy more, the US can’t). And you’re welcome to try to take the islands (which indeed always happens), but Japan not only has the advantage of a large unified force, it is also better situated to take the islands back. So in fact the allies lose more units then Japan in this manner. But the reward is more IPC’s, so we agree that they should try.
Russia/China
Japan has 19 air units. 4 are used in attack on Yunnan in J1 and 3 in Hunan. That leaves 12 planes, plus the bombers which can reach amur from Kwangsi… . 6 planes are used at sea, so Japan has 8 left on Jehol. Japan has 11 landunits on Manchuria plus Korea, and 5 transports in J2. Must be enough.
If you don’t attack in R2, Japan has to re-arrange of course. But from Ahnwe it can reach the whole of China and Manchuria (and Burma). So contrary to what you say the Japanese airforce can threaten northern China and Manchuria at the same time.
Germany would love Russia to invest 4 extra units in China by the way (Szechwan). And again from Ahnwe the Japanese airforce can indeed be a threat to those units. In fact if you don’t put the 18 Russian units forward in Manchuria the forces in Szechwan will all be destroyed in J3…
Still I don’t see how you are going to safe China???
IPC
My assumption is that if Japan takes the treasure islands one time, they have around 70 IPC. If they do they can buy as many ships as the Americans, and the US has to divert power to Europe. Japan also has the advantage of airpower (I like to drop this argument as often as I can :p), of inner lines and they are closer to the islands then the US homebase is.
