Cow, you seem to be saying that any attempts against Japan is futile and full of baloney. You base this on the premise that Japan starts out with more, and can always outproduce America.
Japan only starts with 17 IPC, and is making about 40-45 IPC to spend on the 2nd turn. America starts with 40 IPC, with 48 IPC to spend 2nd turn. While it is true that thereafter Japan usually starts making more, the Allies can work in conjunction to prevent this.
Believe it or not, an Indian IC is possible, but only with a KJF strategy. All it takes is a 6 IPC sub build in SZ35 to make it happen. 4 Russian infantry coupled with a 3 armour/1 bomber purchase in Caucasus ensures that the factory remains intact. A Bry stack can threaten Manchuria, the Russian bomber and the British sub can kill J1 attempts on the money isles and british homeland planes can land in India B2.
The United States can compliment this with a US1 build of 1 CV, 2 TP, 2 SS. US2 can see another CV+DD+SS. B2 can include 2 CV+1 fig and will land the starting fighters, while the Australian DD can meet up with it. This places 2 substantial fleets at either end of the Pacific that can both go on the offensive against the money islands as early as turn 3. Japan never rises above 50 IPC, usually peaks at about 47 IPC on J3, before declining.
This obviously isn’t flawless. The European frontier is left very vulnerable. Yet by US3 or US4, both Africa and the Pacific are secure. A very conservative Russia can, and will, be defended by the returning Commonwealth air force after the Indian crisis (J3). By US4, Japan is crippled, and focus can return back to the European front.
