What should Japan do?

Dear SvO,

My advise would be to stack Washington with everything you have. Bring your fleet back home. Put the light off and ask for mommy. Because the men with iron boots are marching in just one direction. We’re coming to crush you Friday honey!

Great help! This saves a lot of debate…

Thanks Hobbes!

Is it an unprovoked declaration of war if Japan attacks UK forces in Yunnan (China)?

If Japan focus al his powers to India it is hard to defend it. What is the best strategy to keep control?
