It sounds like the taking back and forth of India by the UK is actually a really great strategy to halt the Japanese spamming of tanks, and will hold off their ability to really open an effective new front against the USSR. Because they never get to establish a full turn with the IC.
And if you take the 60-40 spending ratio for the US which @DoManMacgee was mentioning, and buy one bomber a turn to send to UK and SBR Germany every turn…I don’t see how the Axis can win.
…and if Japan then gives up on India realizing how much money is has wasted, US can flip the ratio and spend more on the Atlantic to start landing forces in western europe or add even more bombers and just go after Italy.
So I guess the real question is what can the Axis do against this? Roll for a Radar Tech and hope for the best with the Can Openers into the USSR?
