There is quite a bit of oil off the coast of China, what if Japan discovers it in 1935? How does this effect WWII? Does Japan even get involved as an oil embargo is doomed to failure? If it does how does a reliable source of oil that close by effect its strategy? Japan is still doomed if it fights of course but will it be in range of the B29s to get nuked in Aug 1945 if the war breaks out as in OTL?
