This is basically and extension of this. So basically Japan feels like the Entente is encroaching on its territory and decides to align itself with the central powers. Upon the outbreak of WW1 the Japanese invade Russia (and French Korea for those who wish to follow the scenario). Would Russia spiral into revolution much earlier, due having to fight on two fronts? If the US were to still side with the entente how much longer would the war last and what would be the ramifications for Asia and the world?
