The original titled thread postulated a Japanese attack on the Soviet Union without US and other nation's involvement in the Pacific. I think that in the long run this was quite unrealistic as the US was pushing Japan into a corner. But, let's say the Japanese do make something along those lines occur as the original thread supposes. But, here's the new twist: By the begining of 1942 the British goad the Dutch into cutting off Japanese oil. The US also finally places a full embargo on Japan depriving them of steel, oil, aviation fuel, critical chemicals, and a whole range of other products critical to their industries. At the same time the US has continued to prepare for war as they historically were doing. The later means that there are now two full regular US infantry divisions in the Philippines supported by four plus battalions of tanks half of which are M 3 Lees. The Philippine Army has 10 divisions in the field half of which are in some semblence of shape where they are useful with the others rapidly approaching that point. There are now between triple and quadruple the aircraft in the PI and the new aircraft include P 38 and P 47 fighters along with the better B 17E and F. The US Navy has also put some fighters and bombers there along with more patrol aircraft. There is now a regular radar system with a GCI sytem to back it in place. For the British Singapore and Burma now have better forces and more equipment in place. They too have improved their aircraft situation some but not to the extent the US has. The Dutch have now supplemented their air forces with Curtiss CW 21 and P-40E fighters along with some B-18 and A-20 bombers replacing their ancient B-10s. What does Japan do now?
