Update: Please do not comment. I have moved the post to the correct sub.

Let us consider a scenario where Hitler did not invade Poland and did not kill the Jews, instead focused on building army, technological advancements, roads, industries and created jobs for everyone. Basically equal opportunity regardless of race/religion. No alliance with Japan either.

In such a scenario USSR, US, UK, Germany and Japan would've always stayed in a state of cold-war, one waiting for the other to make a mistake. Do you think things would've been different ? Or we would've had WW2 no matter what.
