[Red Alert 2] If Albert Einstein prevented WW2 by killing Hitler in 1923, how is there still the wreck of the USS Arizona at Pearl Harbor?

Despite WW2 being prevented by removing Hitler from the timeline, in Red Alert 2, we clearly see the wreck of the *USS Arizona* at Pearl Harbor.

How is this possible?

Without Nazi Germany as an ally, it’s highly unlikely that Japan would have still undertaken a pre-emptive strike against the United States.

And even if they still did, with such a significant disruption in the time line, it is EXTREMELY unlikely that the attack on Pearl Harbor and months/years leading up would have unfolded just like it did in the prime timeline.

Just like in Europe, with the removal of Hitler from the timeline, history in the Pacific theater of the Red Alert timeline would have likely unfolded quite differently than the prime timeline.

WW2 wasn't really prevented just altered to by between the Allies and the Soviet Union. 

So instead of Pearl Harbour being attacked by Japanese Forces it was attacked by the Soviets, sinking the USS Arizona.
