I started a thread a few months ago about some World War II stuff I forgot already, but one thing I remember was that if France does not fall, Japan won't declare war on the US because Indochina doesn't fall, etc.
Now the challenge here is that France does not fall [*1] but Japan still initiates Pearl Harbor.
