So why its it that the Arizona memorial in pearl harbour still exists??
History sudent speaking, I can see a Pacific War happening in RAverse. On one hand, the Soviets invade China, breaking the Japanese armies there, probably leadiing the elites to desire a revenge, and for this they'll need more ressources, like the ones of the Western Europeans colonies, also playing in the hands of the Japanese deisre of taking over these empires for their own gains. WW2 à la Red Alert diverts the attention of both the Europeans and Soviets, leaving to the Japanese the opportunity of conquering these colonial empires, with of course the US protesting and ready to protect their on interests in Asia, leading to a war against them probably not so different from our Pacific War. And the Japanese probably attacked Pearl Harbor preemptively, just like in reality.
